Part No. 5-188XU Universal Joint 1480 Series, Greaseable 34.9×106 MM, 1.375 X 4.188 Inch UDS

Designed for Lube fitting in cross, the 5-188XU universal joint delivers dependable driveline performance in the 1480 series. With a 1.375" bearing cap and 4.188" cross width, it provides a direct-fit replacement or upgrade path for worn or damaged OEM joints.

Product Overview

Universal joints wear over time -- the telltale clunk on acceleration and vibration at highway speeds are classic signs that replacement is due. The 5-188XU restores original driveline smoothness with precise bearing cup dimensions that match factory specifications. Grease fittings are included so you can service the joint at each oil change interval.

Technical Data

Dimensional Compatibility

The 1.375" cap diameter is the key fitment dimension for 1480 series driveshafts. Cross width of 4.188" determines yoke span -- always measure existing joint width or consult your driveshaft data plate before ordering. Mixing series or non-matching cap sizes results in improper snap ring groove alignment and premature bearing failure.

Replacement Procedure

• Support the vehicle safely on jack stands with transmission in neutral
• Mark driveshaft-to-differential flange orientation before removal
• Press out old bearing cups using a bench vise or dedicated U-joint tool
• Clean yoke ear bores and inspect for scoring or out-of-round wear
• Install new 5-188XU cross, seat all four bearing cups evenly
• Install snap rings and confirm positive engagement
• Reinstall driveshaft in original orientation and torque hardware
