Shop U-joints for your 2007.5-2010 Chevy/GMC 6.6L LMM Duramax and keep your driveline operating properly. Heavy loads, vibrations due to misalignment, and material wear can lead to loose play within the bearings which can ultimately lead to universal joint failure. 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. U-joint failure can leave you stranded or cause significant damage to your vehicle if it fails while you are driving. Shop all the top brands including Nitro Gear & Axle, Yukon Gear & Axle, and more!
