What precisely is rear differential fluid, then? Why does it need to be replaced and what does it do for your Tacoma?
To retain traction when off-roading, making tight canyon turns, or when towing a load, your Tacoma’s rear wheels must revolve at various rates. In order to retain traction when you need it most, your Tacoma’s rear axle is lubricated with rear differential fluid, which helps to give varying torque to the rear wheels.

How often to change the Toyota Tacomas rear differential fluid
It’s simple to overlook your truck’s rear differential fluid because it doesn’t work as hard as the supercritical oil that lubricates your Tacoma’s engines. In fact, the owners handbook may not even specify how frequently the rear differential fluid needs to be changed.
The following are indicators that your fluid needs to be replaced because it is low or contaminated:
You can increase the lifespan of your Tacoma and avert future catastrophes in addition to keeping an eye out for these symptoms by changing the fluid every 30,000 to 50,000 miles. Toyota advises changing the rear differential fluid on Tacomas closer to 50,000 miles.
However, there are a few explanations as to why you might need to replace the oil more frequently:
It is preferable to change your differential fluid about 30,000 miles if you routinely haul cargo or trailers or engage in extensive off-road driving with your Tacoma.
It is better to change the oil right away rather than waiting until you have driven 50,000 miles if you experience any of the aforementioned symptoms before then.
Let’s go over the steps now that you know what the fluid is and when to replace it.
How frequently should Toyota update the differential fluid?
oil change for the car’s differential
It’s one of the most frequently neglected maintenance procedures for non-FWD light vehicles, SUVs, and cars. The differential doesn’t receive the same attention as the engine up front because it is at the back and under the automobile.
But if the car differential’s lubrication breaks down, you won’t be traveling very far for very long. Thankfully, this oil only needs to be changed every 30,000 to 50,000 miles.
As always, find out how frequently you should maintain your differential by consulting your owner’s manual. Every automobile is unique.
Every car has a differential, which is a part that accounts for the distances that the inner and outer wheels travel when the vehicle is turning a corner. The differential in a rear-wheel-drive car has its own housing and lubrication, which is often a thick, dark oil that weighs more than 80 weight.
Can I replace my own differential fluid?
A differential fluid change is almost as simple as an engine oil change. The procedure can vary from car to vehicle, though, as some differentials just have two plugsone for filling the fluid and another for emptying itwhile others need the housing cover removed. Here is how the procedure is structured simply:
- Place the car on jack stands after using a jack to lift it.
- Locate the fill and drain plugs for the front or rear differential.
- To check that the fill plug is not seized in place, remove it first.
- Remove the drain stopper with caution, then pour the liquid into a pan.
- Put a new drain stopper in.
- Using a hose or pump, pour fluid into the differential housing until it overflows the fill hole.
- Changing the fill plug
The procedure is the same for vehicles and trucks where you have to take off the entire differential housing cover, but you’ll have to undo more bolts to get the fluid out. Use the correct fluid, as specified in your car’s owner’s manual.
Does changing the differential fluid affect the situation?
Metal-on-metal contact generates heat through friction, so it’s crucial to keep track of the changing differential fluid. Additionally, it wears down surfaces and degrades gears. That might result in differential failure, which is an expensive issue.
How much should changing differential fluid cost?
The cost of replacing differential fluid is not excessive. Between $30 to $80 can be spent on the fluid itself, and $40 to $70 can be spent on labor. Depending on your car, where you take it, and how much differential fluid it requires, you may expect to pay anywhere from $70 to $150 to change your differential fluid.
You’ll typically need between 1 and 4 quarts of oil to fill up each differential.
Keep in mind that the price listed above is only valid for one differential housing. Depending on how frequently you have maintenance performed, the cost may need to be doubled if you have all-wheel drive.
What occurs if differential fluid is never changed?
The differential is one of several components on a car that requires regular servicing and maintenance, yet it is much too frequently disregarded. But what does it actually do, and what is it exactly?
Imagine a vehicle with rear-wheel drive turning to the right. The left rear wheel will really have to go further and rotate at a different pace than the right wheel as the vehicle rotates to the right. The left rear wheel would be binding and skidding as it made the turn if the back axle was applying the same torque to both wheels. This issue is resolved by the differential, which enables the wheels to rotate at various speeds around curves.
The oil used in the differential is thicker than engine oil and weighs between between an oil and a grease. But just like any other assembly, the differential’s oil will eventually become polluted and begin to degrade from heat. A fluid change for differentials is often required after 50,000 miles. The differential will start to become noisy and may finally stop working if left on for too long or if the fluid level drops. As a result, the gears may seize, locking the back wheels and perhaps resulting in significant damage or even an accident.
In order to make it simple to check the oil level, differentials contain a fill hole that is occasionally covered by a rubber plug. But because they lack a drain plug, the only method to change the oil in them is to take off the differential’s back cover. Unavoidably messy, this task is better left to experts. Additionally, keep in mind that 4WD cars include a second differential for the front wheels. It’s typically a good idea to service the transfer case and differentials at the same time on 4WD vehicles.

How frequently should a Toyota Tacoma have its gearbox fluid changed?
With regards to Transmission Fluid Change The majority of brand-new cars come with automatic transmissions. There is therefore not much maintenance must be done. However, the majority of owner’s manuals advise changing the gearbox fluid every 90,000 to 120,000 miles.
What signs indicate low differential fluid?
You must maintain optimal performance regardless of whether your vehicle has rear-wheel drive, front-wheel drive, all-wheel drive, or four-wheel drive. Maintaining a proper fluid level in the differential at all times is one approach to guarantee this.
Strange noise
Strange humming, roaring, wailing, and whining noises coming from the front or rear differential are typical signs of a low fluid level in the differential. When accelerating, decelerating, or turning, you’ll hear a progressive change in these noises.
Low fluid levels or worn-out bearings in the differential or axle are the primary culprits of a grinding or buzzing sounds coming from underneath a car.
Overheating differential
A differential might get too hot for a variety of reasons. These include employing the incorrect fluid type, having insufficient differential oil, having ring-and-pinion backlash, overloading equipment, having too much bearing preload, and having old bearings.
In addition to the main causes of diff overheating, poor differential fluid can also cause it.
Burnt oil smell
Burnt oil odors coming from the transmission or diff area may indicate low or faulty tranny or differential oil. Because there appears to be little fluid, not all of the components’ nooks and crannies are properly lubricated.
Additionally, the stench is a warning that the tranny or diff is overheating as a result of insufficient lubrication. It’s possible that the fluid is the incorrect oil kind, has expired, or is too old to effectively lubricate the parts. As a result, there will be metal-to-metal rubbing, which will increase friction and produce metal shavings in the gearbox.
Do not wait to drain and replace differential fluid with new oil if you observe a low level or a poor batch.
Vibrations
A sign of bad differential fluid is vibrations coming from the front wheels while driving in the early morning or while cruising on a sunny afternoon. It can indicate that the difference is aging on its own.
Let’s be clear about this, please. This vibration may be brought on by a number of other broken parts. Therefore, it is best to get in touch with a licensed auto repair to identify and address the problem.
Q: What does low differential fluid sound like?
Low differential fluid levels or worn gears will cause the differential to generate a buzzing or grinding noise. When accelerating, decelerating, and turning in a corner, these noises will also gradually shift. Before it becomes a significant repair job, any unexpected noise should be examined by a qualified mechanic and corrected as soon as feasible.
Q: Can I drive with no differential fluid?
To determine whether one can drive without differential fluid, let’s first examine what it does.
The clutch packs, bearings, and gears are lubricated by the diff oil. Additionally, the entire differential and the ring and pinion gears are oiled. Finally, it cools the diff and keeps it from being too hot.
So, if you’re wondering, “How far can you travel without differential fluid,” the answer is: Never even consider it. Metal-to-metal rubbing from driving without differential fluid will result in too much friction. This implies that the fluid will overheat, self-burn, and present a safety risk. The differential will suffer severe effects, to name a few.
Q: How long can you go without changing the differential fluid?
An essential part of automobiles is the differential. When turning, it makes up for the discrepancy between the inner and outer wheels. It doesn’t need to be changed as often as engine oil, though.
However, if the diff is not well lubricated, you won’t be able to go very far for a while. Fortunately, a car can go between 30,000 and 50,000 miles without needing to change the differential fluid.
Q: What does diff fluid smell like?
The aroma of differential fluid is similar to that of transmission oil or a mechanic’s shop. The diff oil is thick, from dark yellow to black, and it has a synthetic fluid-like odor.
The differential will smell like burning rubber if it overheats and eventually burns the fluid. As soon as you notice a burning smell coming from the diff, have it checked.
Q: What does differential whine sound like?
When slowing down, the differential may whine because to worn-out or loose pinion gears or bearings. From underneath the car, there may be a regular or loud whining sound.
Every time your car makes an odd noise, have it checked out. If neglected for a long time, it will get worse and cost you a lot of money to fix.
Q: What happens when you run out of differential fluid?
Given that the primary purposes of differential fluid are to lubricate and cool the interior components, driving without diff oil is never advised. The pinion gears, side gears, spider gears, crown wheels, and other inner parts will rub against one another when the differential oil runs out. Consider examining the signs of damaged pinion bearings.
The differential will first make a screaming, wailing, and grinding sound. The differential unit will suffer severe damages if you keep on driving with it.
Q: Is differential oil the same as transmission fluid?
The majority of drivers interchange the terms “differential oil” with “transmission fluid.” Do they differ in any way from one another? Viscosity ratings, heat resistance, and pressure tolerance are only a few of the distinctions amongst them.
The function for which differential oil and transmission fluids are used, however, is their primary distinction. Differential oils are designed to function in manual transmissions. Transmission fluids, on the other hand, are created to function in automatic transmissions.
Q: How much does it cost to change the differential fluid?
A simple maintenance task is changing the differential fluid. It entails taking off the diff cover to drain the oil, putting it back on, and then topping off the fluid. This treatment is also known as “transaxle drain and refill.”
It’s easy to alter, and it doesn’t cost much to do so. Changing the diff fluid typically costs between $80 and $90. The mechanic might advise performing additional system maintenance after refilling the fluid.
Is it required to flush the rear differential?
Nowadays, it can be very challenging to distinguish between services that are advised because they are important and those that are merely done so the business can profit.
A frequent service that clients inquire about is fluid flushing. This makes sense, too.
No alerts or reminders exist to flush your brake fluid. No little sticker will be placed on your windshield to serve as a reminder to change your transmission fluid.
To ensure that your car endures the test of time, appropriate fluid maintenance is crucial. In this post, we’ll look at the benefits of fluid flushes for your car and when you might need to conduct them.
What is a Fluid Flush?
An oil change is technically a fluid flush. To enable its parts to function, your car need a variety of fluids.
These vital fluids accumulate dirt and other pollutants over time. This may lessen their efficiency or maybe render them damaging to your car.
A fluid flush entails completely draining one kind of fluid from your car and replacing it with fresh, clean fluid.
Although different manufacturers recommend different service intervals for different cars, all manufacturers advise changing your fluids on a regular basis. The type of fluid determines these intervals.
Transmission Flush
A particular kind of oil must be used in your car’s transmission for it to operate properly. This oil, which is also known as transmission fluid, accumulates dirt and grime over time.
Your transmission system may become clogged by the coagulation of this debris. One of the most expensive parts of your car, the transmission, can suffer significant harm from these jams.
Many manufacturers advise waiting until 75,000100,000 miles to change your gearbox fluid. However, many professionals advise doing this service every 30,000-50,000 miles for customers who wish to prolong the life of their transmission.
Every 15,000 miles, you should change your transmission fluid if you often travel short distances and stop and start, such as when making deliveries or doing other demanding driving tasks.
Not just automatic transmissions require fluid upkeep. Even though manual gearboxes utilize a more common oil, regular maintenance is still necessary.
For most cars, a brand-new automatic transmission starts at roughly $3,500. The greatest approach to increase the lifespan of your transmission is to do routine fluid maintenance, which makes them expensive but well worth it.
Engine Coolant (Anti-Freeze) Flush
Vehicles have started using 5-year or 10-year coolant as of 2011. As a result, it is no longer necessary to change these fluids as frequently.
However, coolant plays a crucial role in safeguarding your enginethe vital component of your car. Because of this, it appears prudent to at least check your fluid levels more frequently than that.
Request that your mechanic check your coolant while they’re under the hood because you’ll be approaching additional service intervals every 30,000 to 35,000 miles. If there are issues, it’s preferable to find out now rather than later.
Make sure to do this service on older models of cars every 50,000 to 75,000 miles.
Power Steering Flush
A lot of manufacturers claim that their power steering fluid is lifetime. Of course, it isn’t always the case.
A lot of strain is placed on your power steering fluid. Every time the car is operating, it is exposed to the heat of the engine. In the winter, it is also vulnerable to extremely cold temperatures. The fluid may begin to break down early as a result of this back and forth.
Pumps, hoses, and steering gear seals can all suffer serious harm from faulty power steering fluid. This will eventually cause your power steering system to malfunction. This condition may be quite hazardous.
Because of this, mechanics advise replacing a power steering fluid flush every 50,00075,000. Given its significance, it is also important to examine during other significant service intervals.
Brake Fluid Flush
The most frequent fluid service, excluding an oil change, is probably a brake fluid flush. And with good cause.
Not only is brake fluid crucial, it is also one of the parts of the car that is most likely to collect dirt and filth. Brakes that are ineffective are ineffective brakes. Ineffective brakes are really, extremely dangerous.
Additionally to dirt and other impurities, water can enter your braking fluid quite easily. This is a result of condensation gradually accumulating over time. Your ability to stop when you need to can be significantly hampered by water in your brake lines.
Your brake fluid should be transparent or clear. Your brake fluid is polluted if it has a distinct hue, particularly a brown one. Visit your repair right away if you smell burning or your brake fluid is dark. This indicates that your brakes are failing.
Change your brake fluid every two to three years, or every 24,000 to 36,000 miles, depending on the age of your car, to avoid such a risky situation.
Fuel Injection Flush
The fuel system of your car has a major impact on how well it performs. Poor gas mileage has many causes, but the main one is clogged fuel systems.
Your car’s fuel injection system plays a significant role in how it operates. It makes sense, therefore, to have your fuel system cleaned every 30,00035,000. This service will almost definitely pay for itself only from the gasoline savings.
However, compared to some of the other flushes listed, cleaning a fuel system is a little more difficult. Many shops lack the necessary equipment and abilities for it. This is why it’s crucial to use an ASE Certified technician for the servicing.
Rear Differential Flush
One of the services that you probably haven’t heard of or considered before is this one. Although it is one of the most frequently disregarded services, rear-wheel drive drivers cannot do without it.
The rear differential in a RWD system has its own lubrication. This prevents slippage, locking, or a general breakdown of the differential by keeping all of its tiny pieces working smoothly.
A rear differential is an extremely expensive item to replace or repair. For this reason, it is advisable to check and replace these fluids at least every 30,000 miles.
Fluid Flushes Conclusion
Your car is probably one of your most expensive possessions. While you may be able to avoid conducting some of these fluid flushes, you run the risk of drastically shortening the operational life of your car.
Some of these services, like a brake fluid flush, are crucial to the functionality and safety of your car. Other services, such as a rear differential fluid flush, can frequently offer useful details regarding the condition of your car.
Nevertheless, regular intervals are merely estimates. Everyone has to deal with various road conditions. Severe weather may entirely alter the math of how long such intervals should be depending on where you reside.
Thorough testing is the only real way to determine whether or not it’s time for a fluid flush. Comprehensive, in-depth diagnostic testing is available as a service from StrutDaddy’s. You can determine with certainty using these tests whether or not your car will benefit from a fluid change.
