How do I know if my driveshaft U-joints are bad?
Signs of a Loose U-Joint
- Clunking/clanking noise when you shift gears.

If a u-joint is excessively worn, there’s an easy test you can perform. With your foot on the brake, shift the car into reverse. Then, shift into drive. If the vehicle makes a clunking sound, or you can feel it knock one time after engagement, a u-joint is likely the culprit.

How long do u-joints usually last?
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.
What does a bad driveshaft sound like?
Another symptom of driveshaft issues is loud clunking noises. These noises are usually produced by worn-out u-joints. The ability of your driveshaft to rotate correctly is altered if your vehicle has a faulty u-joint. Lack of u-joint lubrication can cause squeaking noises when you drive at low speeds.
Are u-joints hard to replace?
Replacing these joints is a fairly straightforward job, though it takes some prior experience. To begin, you’ll need a universal joint pressing tool. You can also take advantage of the loaner tools program at your local Advance Auto Parts store. Then follow these step-by-step instructions on how to change U joints.
Can bad u-joints cause death wobble?
The biggest issue with death wobble is that it can have so many more causes than say, a driveline vibration, which can typically be narrowed down to a bent driveline, improper angle, or worn u-joint. Death wobble doesn’t always occur under the same circumstances either making it difficult to diagnose.
Can a bad U joint cause loss of power?
Universal joints, being a heavy-duty component in off-road and rear wheel drive vehicles, can undergo many issues that lead to its failure. These can severely affect the movement of the vehicle and can cause great losses in the rotational power and torque transmitted from the engine to the wheels.

Common signs include intense car vibrations and abnormal noises, like clunking, rattling, and scraping, coming from under the vehicle.

What is a drive shaft u-joint?
Most driveshafts have one or more u-joints. The u-joints allow the driveshaft to move up and down in response to changes in the vehicle’s suspension geometry. A typical u-joint consists of a cross-shaped center portion (called a trunion) and four cups filled with needle bearings. The cups also contain grease to keep the needle bearings lubricated.
Why does my car vibrate when the U-joint is bad?
Your vehicle may experience vibration and imbalance when your U-joint is in a bad state or is broken. In the case of vibration, the U-joint bearing is worn enough to allow the rotation of the drive shaft outside its normal path. And since the drive shaft rotates at higher speeds, the vibrations are of high frequency.
