Repair your driveline with the wide selection of U-joints for your 2011-2016 Ford 6.7L Powerstroke. A bad U-joint can cause a clunking sound or jerkiness while driving, particularly when pressing on or letting off the accelerator pedal. A bad U-joint can also cause vibrations at certain speeds, originating from the center or rear of the vehicle. Over time due to wear and tear from the lack of lubrication, heavy-duty tasks, modifications to the vehicle, and even your driving habits can ultimately lead to universal joint failure. U-joint failure can leave you stranded or cause significant damage to your vehicle if it fails while you are driving.
