Shop U-joints for your 1999-2003 Ford 7.3L Powerstroke and keep your driveline operating properly. If the U-joint fails, it could leave you stranded or cause serious damage if the driveshaft dislodges while you are driving. 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. Symptoms of a bad U-joint can include clunking sounds, squeaking or clicking noises, and vibrations most noticeable at highway speeds. Shop all the top brands including Nitro Gear & Axle, Yukon Gear & Axle, and more!
