U-joints should last forever ' or at least the life of the vehicle. 'Should' is the operative word here. U-joints aren't supposed to wear out, but it happens. Also, u-joints can break.
With competitive price and timely delivery, RUNCHI sincerely hope to be your supplier and partner.
It's easy to predict the lifespan of some car parts, such as shocks. But not u-joints. U-joints can last decades, or they can break when the vehicle is still new. That's why it's a good idea to check the u-joints at every oil change. A typical rear wheel drive vehicle has 2 or 3 u-joints. Some vehicles with a long wheel base, such as buses, have 3 or more u-joints. The more u-joints a vehicle has, the higher the chance a u-joint will fail.
What Could Cause A U-Joint To Fail?

Most of the time, you can attribute u-joint failure to one of the following reasons:
- Improper lubrication: Some u-joints need regular maintenance. In most cases, you have to grease your u-joints every 5,000 miles or so. When you fail to service your u-joints on a regular basis, they will fail. You don't have to worry about this problem with maintenance free u-joints.
- Misalignment: This happens when you change the vehicle's ride height. The u-joint operating angles change if you lift the vehicle. The greater the operating angle, the more the u-joint moves with each rotation of the driveshaft. This wears the u-joint out faster.
- Loose connections: The bolts holding the u-joints in place can get loose or fall out over time. This happens usually because of corrosion, excessive vibration, or improper torquing.
- Wear and tear: Even though u-joints should last the lifetime of the vehicle, they can wear out early. This is common on off-road vehicles or vehicles that tow frequently.

What Happens When You Don't Replace Your U-Joints?
A u-joint may seem like a small and insignificant part, but its failure will eventually render the vehicle unusable. The driveshaft will no longer be able to spin anymore. That means you won't have anything to turn the wheels anymore. It won't happen out of the blue, though. You'll notice some symptoms leading up to the event. Some symptoms include:
- Vibration when accelerating or decelerating
- Clunking noises from the underside of the vehicle when changing direction from foward to reverse or reverse to forward
- Leaking from the rear pinion seal and/or transmission seal
If you replace the u-joint(s) when you notice these symptoms, you'll avoid the major hassle of complete failure.

Quality Matters
If one of your u-joints has failed, the right replacement parts will make all the difference. It's important to replace your u-joints in pairs, even if one of them seem like it is still good. If one has failed, the other doesn't have long to live.
