U-Joint SpiderThis aftermarket U-joint spider is the four-legged cross at the heart of a universal joint, with needle bearings on each trunnion that allow articulation between input and output yokes. It is the wear component in a U-joint and is typically replaced as a complete assembly with new bearing caps. Forklift driveline rebuilders and fleet maintenance shops buy them for driveshaft service on Class IV and V trucks. Sold as a crossover aftermarket replacement, not OEM. Confirm cap diameter, span across trunnions, and bearing retention style against your existing U-joint before installing.Aftermarket replacement part, cross-references original part number AC0180132.Need help confirming fit?
