5-3012X UDS Universal Joint – 3CRL Series -3CRL Series, …

The 5-3012x is a 3CRL series combination (OSR + ISR) snap ring retention universal joint measuring 1.124"/1.437" dual cap | 2.370"/3.560" dual width. This is a combination u-joint -- it bridges two different series in one cross. The 5-3012x is greaseable with zerk fitting. Every 5-3012x is verified for cap diameter, bearing width, and snap ring groove dimensions before it ships from Universal Driveshafts.

5-3012X -- 3CRL Series Cap & Width Specifications

The 5-3012x specs: 1.124"/1.437" dual cap | 2.370"/3.560" dual width. Cap diameter determines which yoke bore it fits -- the cap must seat fully into the yoke without play. Dual cap diameters (1.124" and 1.437") bridge two different series yokes in a single cross. Bearing width (2.370" and 3.560" across the body) controls the span between yoke ears. A cross that is too wide won't fit; too narrow and the snap rings don't seat in the groove. CP3012 heavy duty.

Confirm both ends of the driveshaft before installing the 5-3012x. Combination u-joints require matching the correct series at each end -- the 1.124" caps go into one yoke, the 1.437" caps go into the other. Getting the orientation wrong means the driveshaft won't balance and the 5-3012x will fail early. Measure both yoke bores with calipers before ordering -- don't rely on the vehicle spec alone.

Installation Notes for 5-3012x

Before installing the 5-3012x, clean the yoke bores of any rust, burrs, or old bearing material. The bearing cups must drop in by hand -- never drive them in with a hammer directly on the cup. Use a proper cross-and-bearing installation tool or a press. Driving a cup in at an angle cocks the needle bearings and destroys the 5-3012x before it ever sees load.

After installation, verify full rotation without binding. A binding cross indicates a cup is cocked or seated too deep. The 5-3012x should articulate freely through the full operating angle of your driveshaft before the vehicle is lowered off the lift.
