- Reassemble everything in the manner in which it was taken apart.
- On the opposite side, repeat.
Is it possible to drive with a broken rear axle seal?
The component of the car that joins the axle to the transmission or the rear differential is called an axle seal. The axle seal’s job is to prevent transmission fluid leaks. You might be able to drive with a leaking axle seal for a short while, but only depending on the size of the leak.
Here are 2 warning signs of an axle seal leak, in case you’re worried:
under-car oil puddle Oil beneath your car after it has been parked is one of the more typical indications that the axle seal is leaking. One of the places you’ll notice the oil leak is in your driveway. If oil begins to drip on your driveway, it can indicate a leaking axle seal.
At motorway speeds, the transmission slips. Despite being a common indicator, an oil patch on the driveway does not always appear since the axle seal leaks more when traveling on the highway. Instead, at highway speeds, you can feel your transmission slipping. Since the transmission fluid level declines, there isn’t enough fluid to lubricate the gears, the torque converter, the brake band, or the valves. Transmission damage may be irreversible if the leaky axle seal is not replaced right away and the transmission is slipping.
The level of the leak determines how risky it is to drive while the axle seal is leaking. The car shouldn’t be driven if there is a large fluid leak that compromises the transmission. Driving your car is safe as long as you maintain the transmission fluid full if the leak is little and you won’t be able to make it to an appointment for a few days. However, avoid going too far because repairing a damaged transmission would cost a lot of money.
Incorrect axle installation or removal is the most frequent cause of a leaky axle seal. The axle seal may also start to leak as a result of wear and tear over time. You should examine your car’s brochure to see if the Powertrain Warranty covers an axle seal that is leaking.
If your automobile has a little axle seal leak, you might be able to keep driving for the time being, but you should get the axle shaft checked out and possibly replaced right away. Keep your transmission fluid filled to ensure smooth operation of your transmission. Drive with a leaky axle seal if your transmission is slipping and you have a significant leak.
How dangerous is an axle seal leak?
You might be able to drive for a little length of time depending on the severity of the leak, but it is not recommended to do so for too long. By doing this, you run the risk of severe harm to your car or perhaps its total breakdown.
If left unattended, a leaking axle seal can harm your car significantly. If you see any fluid dripping from the vicinity of your axle, you should have a mechanic examine your car as soon as possible.
Why do rear axle seals deteriorate?
The axle seal prevents transmission fluid leakage by joining the axle and transmission. You might be able to drive with a leaking axle seal for a short while, but only depending on the size of the leak.
Common Causes
Although faulty axle installation or removal is the most frequent cause of a leaky axle seal, the axle seal can also wear out over time. Here are a few signs that your axle seal may be leaking if you’re worried about it:
- Transmission begins to slip when you’re on the freeway. Due to the axle seal’s tendency to leak more at fast speeds, you might not see any marks on your driveway. You risk causing the transmission irreparable harm if the seal is not quickly restored.
- After you park your car, oil drips from beneath. If oil begins to drip on your driveway, it can indicate a leaking axle seal.
Is it safe to drive?
How risky it is to drive will depend on how severe the leak is. If there is a substantial fluid loss, the car shouldn’t be driven; if the leak is modest, you might be able to keep driving it as long as you keep the right levels of transmission fluid.
How much will it cost to fix?
Depending on the type and model of your car, fixing an axle seal might run you anywhere from $150 to several hundred dollars. It’s best to correct leaks as soon as you notice them because repairing a damaged transmission can be pricey. Check your car’s brochure to discover if an axle seal leak is covered by the Powertrain Warranty of your vehicle.
Is it safe to drive with a leaky rear differential?
Oil trails on the underside of the car are among the earliest signs of a differential gasket issue. The differential gasket may start to leak oil as it gets older. The differential housing’s undersides may noticeably show signs of oil on them, depending on how much oil seeps through the gasket. For a while, a leaky differential is normally safe to drive, but over time, it will inevitably turn into a full-on leak.
Are an axle seal and a wheel seal interchangeable terms?
Wheel seals and axle shaft seals may be familiar to you. If you’re here, you might be curious as to what the distinction between the two portions is.
These words are sometimes used interchangeably. Actually, these are various components. It is true that both components are comparable. They nevertheless belong in various places. Choosing the correct component is important if you need to buy a new seal for your axle.
Which seal(s) is your axle equipped with? The kind of axle you have makes a difference. Let’s first go through each seal in more detail.
What should you do if your rear differential leaks?
On the underside of the differential is the differential cover. There will be a seal if the differential cover is a distinct component from the differential. Differential fluid will leak from the side of the cover and drain along the bottom if the seal is failing. There could be discolored patches on the differential cover.
How to Fix the Differential Cover
- the drain pan.
- Remove the differential cover’s bolts.
- Remove the differential cover by pried.
- Drain the differential oil.
- Gasket from differential pan should be removed.
- Both the differential pan and the differential should be cleaned.
- affix a fresh gasket to the cover.
- changing out the differential cover
- Torque the bolts according to the manufacturer’s recommendations.
- New differential fluid should be added to the differential.
- Take the car for a test drive.
What causes wheel seal leaks most frequently?
incorrect installation and upkeep The most frequent reason for wheel seal failure is incorrect wheel seal installation.
What effects does a faulty axle seal have?
The axle coming out all the time is another sign that there might be an issue with the CV axle shaft seal. In some automobiles, the axle shaft seal supports the CV axle in addition to sealing the gearbox and axle mating surfaces. The seal may start to leak if it sustains any kind of damage, but it may also lose its ability to correctly hold the axle and pop out or become loose as a result. To get the car back on the road after a loose shaft, the shaft must be fitted properly.
Since the CV axle shaft seals are responsible for maintaining the fluid levels in the gearbox and differential, when they malfunction, fluid may start to leak, putting the transmission or differential at danger of overheating and sustaining damage. For this reason, you should see a qualified mechanic, like one from YourMechanic, to identify the best course of action if you find that your CV axle seal is leaking or think it might need to be changed. If necessary, they will be able to replace your CV axle shaft seal and do any additional repairs you require.
What does having a leaky back end mean?
Gear oil, which lubricates the gears and bearings and cools them to prevent overheating, surrounds the gears inside the rear differential. Metal shavings from the gears and bearings accumulate in the fluid as it degrades over time. Rear differential fluid replacement is occasionally necessary. To avoid harming the ring gear and pinion gear, two internal gears, the gear oil must be changed.
The steps in a rear differential service include removing the rear differential cover, cleaning the differential case of any old fluid, resealing the cover, and adding fresh fluid. The average car will go between 20,000 and 40,000 miles after a rear differential fluid change before another one is necessary.

How long may a leaky axle boot be tolerated while driving?
Up until it starts to make a clicking noise when turning, you are safe; beyond that, you must replace the entire CV joint. If you choose a remanufactured unit, the company may not accept your core if you drive it for too long. You “should” be fine after 50 miles.
How bad is the leak in the rear differential?
It’s critical to have a rear differential leak rectified as soon as possible. Depending on the leak’s intensity, your car can get damaged or perhaps become undriveable. Repairing a rear differential leak often costs between $150 and $2,000 in total. This is a sizable bracket, but the cost of repair would depend on which portion or parts have failed. Let’s examine that specifically:
If your differential gasket is damaged:
A replacement differential gasket typically costs between $350 and $450. While parts are priced between $183 and $239, labor costs are predicted to range between $167 and $211. This price range implies that the front and rear differential gaskets will need to be replaced at the same time and excludes taxes and fees.
If your axle, side, or rear differential pinion seals are damaged:
A Differential Pinion Seal Replacement typically costs between $184 and $217. Between $109 and $189 is the projected range for labor costs, while $20 to $40 is the estimated range for parts. Nevertheless, the precise price may vary according on the brand and type of your car. If the rear main seals are damaged, the cost of replacing them or fixing an axle seal leak will be included. As a result, the replacements must be completed right away.
If the differential cover has been harmed:
Although they are not the most expensive component of your car, differential covers are also not inexpensive. A new differential cover will cost you between $100 and $300, depending on the make and model of your car. Nevertheless, the price of repair will vary based on the extent of the damage and whether you also need to replace any other parts.
In the event that the entire differential fails:
Depending on the type and model of your car, the cost to replace a differential will change. The majority of diffs must be professionally installed, which means that labor expenses will rise significantly. For the majority of rear-wheel drive automobiles, budget between $1,000 and $2,000 because the parts themselves are not cheap.
