Repairing and Replacing your U-Joint

The U-joint, or universal joint, is a rigid rod that allows it to bend in any direction and it is usually used in driveshafts. Their main purpose is to transfer engine power and torque from the transmission to the differential and wheels as the suspension continues to travel.

The universal joint allows the driveshaft to spin the engine power and handle the torque no matter what condition the road is in. Over time all of the constant spinning will cause the joint to wear out and grease to run thin.

Note: It is sometimes hard to determine what exactly is wrong just by noise but a damaged U-joint will emit a clicking or clunking sound coming from the driveshaft.

Try to pay attention to when you hear the noise happen as well. When you put the vehicle in gear you may feel a vibration that increases with speed and you could hear a clunking sound at this time too.

To confirm your suspicions of a worn out U-joint you’re going to need to remove the driveshaft. Each make and model may have their driveshaft and U-joints set up differently so you may need to check your owner’s manual before you approach the situation.

Once you’re able to have the driveshaft removed you can then rotate the U-joints by hand to see if you notice any inconsistent moving or noises. Most of the time it would be better to completely replace the entire U-joint but if you think a repair will suffice then use your best judgment.

However if you don’t feel comfortable as your vehicle’s mechanic then it would be wise to bring it in to 2J’s Automotive and let the professionals service and repair your vehicle for you. They will give your car a free diagnostic test (valued at $80) to help determine what the problem is and where it is coming from.
