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.
There are typically two u-joints to replace on either end of the drive shaft. Some driveshafts have a double-cardan joint at the front, which contains two u-joints. So there are three U-joints to replace. It’s best to replace them all at once.
How much does it cost to replace 3 U joints?
Are u-joints expensive? The estimated U joint replacement cost is between $225 and $300. Labour and parts make an additional $100 to $125 and $125 to $200 respectively to the overall cost of your u joint replacement. However, these costs are dependent on the car make and model.
A bad u-joint can cause a clunking sound or jerkiness while driving, particularly when letting off of and pressing the accelerator. A bad u-joint can also cause vibration at certain speeds, emanating from the center or rear of the vehicle.
