U-joints ought to endure for the duration of the vehicle or indefinitely. U-joints aren’t meant to wear out, but it does happen, and they can also shatter. Should is the crucial word here.
A typical rear wheel drive vehicle has 2 or 3 u-joints, while some vehicles with a long wheel base, such as buses, have 3 or more. The more u-joints a vehicle has, the higher the chance a u-joint will fail. While the lifespan of some car parts, such as shocks, is predictable, u-joints are not. U-joints can last decades, or they can break when the vehicle is still new.

How many U-joints are necessary?
On either end of the drive shaft, there are normally two u-joints that need to be replaced. Some driveshafts have a front double-cardan joint with two u-joints on them. So, three U-joints need to be replaced. Replace them all at once if possible.
What is the price of replacing three U-joints?
Between $225 to $300 is the expected cost of a new u-joint. While labor costs between $100 and $125, parts should run between $125 and $200.
Nevertheless, these costs change depending on the brand and type of the car you drive. If you have the necessary tools and are mechanically inclined, you can replace your own U-joints.
What number of U joints are there in a Toyota Tacoma?
How many U-joints are there in a Tacoma? To replace the carrier bearing, you must completely remove the drive shaft. When that happens, you can also use all three universal joints.
What is the turnaround time for replacing U joints?
Some individuals will claim that a hydraulic press is required to replace U-joints; however, those individuals are mistaken. The goal of Wrenchin’ Wednesday is to simplify shop methods and equipment so that the home gamer can use them, and this week we’re going to lift the curtain on driveshaft maintenance. U-joints are a wear item that can sneak up on you and fail at the worst possible time, putting your project out of commission and putting you at risk of significant damage from a newly liberated driveshaft once the joints catastrophically fail, whether you’re chasing a mysterious vibration at higher speeds or listening to those poor needle bearings chirp in the morning. A U-joint repair typically takes one to two labor hours, so if you hire someone else to install it and they charge you about $100/hour, your $25 part could end up costing much more.
The truth is that you can easily remove damaged U-joints and finish the repair as an afternoon project with a few sockets you probably already have in your toolbox, a hammer, and a simple bench vise.
Starting with step one, remove your car’s driveshaft. Put the vehicle’s rear on ramps or jack stands to help the fluid surge away from the tail shaft seal we’re going to uncork since most driveshafts seal against the gearbox or transfer case. Additionally, since you’ll be moving the driveshaft about a lot on the bench while working on it, shielding the polished surface of the slip yoke with an old sock or even painter’s tape will prevent damage that could later cause a leak.
2. Next, locate three sockets that can be used as pressing tools, two of which should be slightly smaller than the U-joint caps and one of which should be somewhat larger so that they can slip into it when removing the shaft. Although the U-joints on this 3/4-ton 1996 Suburban K2500 are larger than what most people will be working with, I discovered that a CV axle socket worked best for my large socket.
3. You have two choices for this phase. One option is to utilize the vise as a huge screw press, but you’ll need a sturdy one for this because the wide-spaced jaws will put a lot of strain on the vice (you can see where the slide on mine is fractured from previous abuseit finally chipped off during this shoot). If everything is extremely rusted, save this option until last. The majority of the remaining work will consist of hammering the caps out. Choose your weapon and begin pressing the first cap out in either case.
4. Flip the joint over and repeat the technique to start popping the opposite cap out. Hammer until the joint slides up against the inner ear of the driveshaft.
5. The U-joint should be able to move out once both caps have been pushed as far as they can go.
6. From a distance, it is clear why this attempt failed. The rust on these 259,000-mile factory joints indicates that they are “lifetime U-joints without any means of lubrication, which is what caused these to dry up and start taking in water.” The U-joint developed those ridges like a washboard road as the needle bearing moved because there wasn’t enough lubrication to prevent the needles from wearing into it. When I grabbed and twisted the driveshaft beneath my Suburban, it was still snug but made a high-pitched chirping noise at low speeds. They don’t always get careless before failing; this guy was destined to seize up and break at some point.
7. Use a screwdriver or punch and hammer to remove the remaining caps from the back side, and then clean up the bores of any rust or gouges left behind by removing the U-joint. In order for the joint caps to go in smoothly and uniformly, you want these to be as clean and free of nicks and scratches as possible.
8. Now comes the most challenging step of the procedure: mounting the new U-joint before pressing it in. Put some tape over the two caps that you won’t be working with while installing them first, and make sure the grease zerk is inserted so that it faces the driveshaft when you put the caps on. Anyone who has dropped one knows the nightmare of attempting to get them to stick back inside in an ordered fashion without any driveway grit getting caught in the oil. These caps are full of tiny needle bearings that must be maintained together and clean. The driveshaft should then be loaded into the vise with the U-joint floating in one of the ears after manually pressing the caps into place. Press the caps in firmly but gently, paying attention to the alignment of the U-joint where it meets the other cap.
9. If necessary, offset the vise jaws to press on a cap edge if it is initially not going in straight. Work carefully as you insert the U-joint into the other cap and then apply pressure until the jaws of the vise are just contacting the drive shaft’s ears. Here, very tiny modifications of the vise result in significant changes. The U-joint should now be supported by both bearing caps, albeit with additional lateral play while the caps are still being seated.
10. After the cap has been pressed in a few millimeters to clear the C-clip groove, insert the C-clip using one of your small sockets.
11. Once the first C-clip is in place, secure it with the second tiny socket and firmly press the opposing cap into position until the second C-clip can be attached.
12. At this point, rotate the joint by hand with a little bit of effort. If the caps are a little too tightly packed in, however, a few light taps on the driveshaft ear with the horizontal caps held by the vise will loosen it up. Work lightly at this point.
13. Don’t forget to oil it after installation! It should only take three to five pumps, but stop as soon as you notice that the seals on the bearing caps are starting to swell with grease. It’s inexpensive insurance to replace your worn-out and rusted retaining hardware right away. Drive a short distance, check them again after a few kilometers, and mark them if you want to keep an eye on them later. Tighten the driveshaft to specification. On this specific project, just the axle-side required a U-joint, but the method is the same for slip-yoke ends; the only difference is that you must press all four caps free twice.
How durable are driveshafts?
The driveshaft has a lot of significance when it comes to crucial parts of your car. This component is in charge of sending the torque, or power, produced by your engine to the desired location. Your automobile will send power there if it has rear-wheel drive, there if it has front-wheel drive, and it will send power wherever it is needed if it has four-wheel drive. Two driveshafts may occasionally be present in four-wheel drive cars to ensure adequate power.
Unfortunately, when this component gets closer to the end of its useful life, it won’t be able to deliver that power without problems. As a result, other parts of your car will have to pick up the slack and carry more of the load, which means you’ll be wearing them out much more quickly. The driveshaft will eventually fail to the point where the wheels won’t receive any power if you let it.
A driveshaft’s lifespan is variable, however it normally lasts for roughly 75,000 miles. Remember that the amount you receive could vary greatly based on the car and wear and tear. Your driveshaft is more likely to sustain damage if you have adjusted its height, which means you will need to repair it sooner. Make sure all of the u-joints are thoroughly lubricated as one suggestion to lengthen the life of your driveshaft.
Here is a complete list of symptoms if you’re wondering how to tell whether a driveshaft is beyond its prime.
You can start to hear a squeaky sound while driving. It could begin as sporadic and gradually intensify.
You might feel a vibration while driving and notice it. Again, if the driveshaft wears out more and more, this can become more powerful over time.
A clunking noise can start to occur as you speed and switch between reverse and drive.
It’s crucial to have the driveshaft inspected if you believe yours has reached the end of its useful life because you don’t want to risk injuring other components of your car. It’s critical to schedule a driveshaft replacement service with a qualified mechanic as soon as you notice any of the aforementioned symptoms and suspect that your driveshaft needs to be replaced.
I have what U joints?
Having the proper set of universal joints, also known as U joints, is essential for the proper operation of your drive shaft. U-joints come in a wide variety of series. We offer a large variety of U-joints for numerous series. If there is an u joint that you need but we don’t have it in store, we can simply order it for you along with other parts.
The first thing to determine when identifying U-joints is whether the U-joint has inside or outside snap rings.
Finding the dimensions of your U-joint comes next after determining the arrangement of the snap rings. The diameter of one of your u-joints’ caps must be determined. For u-joints with inside or outside snap rings, this needs to be done. The second dimension, which you must identify, differs for the two kinds of u-joint configurations.
All of the u-joint caps have a groove if the u-joint has inside snap rings. You must take a measurement straight across from the edge of one snap ring groove to the edge of the other. Measure from the edge of one u-joint cap straight across to the edge of the other u-joint cap for U-joints that have outside snap rings.
It will be simple to determine what sequence of U-joints you have using these dimensions. Taking accurate measurements of the pinion yoke is another method of identifying a u-joint.
You can determine your u joint by taking the measurements shown in each of the diagrams below.
Can a broken Ujoint be used to drive?
How Long Can a Bad U-Joint Be Driven With? If you suspect that your u-joint may be damaged, you should take immediate action. If a u-joint totally fails, the driveshaft could escape the underside and cause serious damage to the automobile, possibly even an accident.
Is it difficult to replace u-joints?
These joints can be replaced pretty easily, but it helps to have some prior knowledge. You’ll need a universal joint pressing tool to get started. Additionally, you can benefit from the loaner tool program at your neighborhood Advance Auto Parts. then adhere to these detailed directions for replacing U joints.
What noise does a failed U-joint make?
Squeaking noises, clunking noises during shifts, vibrations within the car, and transmission fluid leakage are typical symptoms of a bad u-joint.
How can I tell if my u-joints need replacement?
U-joints are a little, straightforward part that have seen significant development since the earliest autos. However, the existence of the u-joint is absolutely necessary for any vehicle with a driveshaft to be able to move. It’s common to hear “maybe it’s the u-joints” suggested as a fix for car problems, but what exactly are they, what do they do, and how can you tell if yours are bad? The solutions are at Hale’s Automotive in Marion, Illinois.
A u-joint, also known as a universal joint, is a part that joins the driveshaft to the differential and, on occasion, the transmission or two driveshafts. The driveshaft can move laterally and side to side thanks to a cross-shaped section with bearings at each end.
With the use of a u-joint, the driveshaft, transmission, and differential can all be slightly moved. In other words, even if the driveshaft joins the transmission and differential, it cannot be a rigid, static connection. The transmission and differential are not always completely aligned with one another since the differential travels through terrain independently of the rest of the car. The driveshaft is attached and can spin freely thanks to the u-motion-compensating joint’s capabilities.
It’s crucial to keep in mind that damaged u-joints primarily affect rear-wheel drive cars, trucks, and SUVs. A damaged u-joint is visible to a professional who understands what they’re searching for because it exhibits particular symptoms. When releasing the brake and applying the accelerator, in particular, a damaged u-joint can make the car jolt or make a loud noise. At certain speeds, a damaged u-joint can also cause vibration to come from the center or back of the car. There is a quick test you may use to determine if a u-joint is too worn. Put the car in backward while keeping your foot on the brake. then put the car in drive. A u-joint is probably to blame if the car makes a clunking noise or you feel it knock once after engagement. As it degrades, it no longer forms a tight connection to the driveshaft and differential, allowing for excessive play at the joint.
Fortunately, replacing a u-joint is simple and affordable, and one of our specialists can get you back on the road quickly. Our professionals will conduct a diagnosis before performing any necessary repairs if you want a second opinion on whether or not your u-joint is failing. Get it mended as soon as possible because if it totally breaks, the driveshaft will separate from the car and cause damage to the transmission, the underbelly of the car, and anything else around. In addition, the car won’t move until it is fixed. We want to offer skilled repairs and servicing in advance because we don’t want it to happen to our drivers.
