1351-31 UDS Universal Joint Combo Conversion U Joint 131…

The 1351-31 is a 1310X1510 series -- light-duty trucks (F-150, Silverado 1500, Jeep Wrangler, Ram 1500) combination (OSR + ISR) snap ring retention universal joint measuring 1.142"/1.063" dual cap | 2.047"/3.219" dual width. This is a combination u-joint -- it bridges two different series in one cross. The 1351-31 is greaseable with zerk fitting. Every 1351-31 is verified for cap diameter, bearing width, and snap ring groove dimensions before it ships from Universal Driveshafts.

1351-31 -- 1310X1510 Series Cap & Width Specifications

The 1351-31 specs: 1.142"/1.063" dual cap | 2.047"/3.219" dual width. Cap diameter determines which yoke bore it fits -- the cap must seat fully into the yoke without play. Dual cap diameters (1.142" and 1.063") bridge two different series yokes in a single cross. Bearing width (2.047" and 3.219" 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. TOYOTA.

Confirm both ends of the driveshaft before installing the 1351-31. Combination u-joints require matching the correct series at each end -- the 1.142" caps go into one yoke, the 1.063" caps go into the other. Getting the orientation wrong means the driveshaft won't balance and the 1351-31 will fail early. Measure both yoke bores with calipers before ordering -- don't rely on the vehicle spec alone.

Installation Notes for 1351-31

Before installing the 1351-31, 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 1351-31 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 1351-31 should articulate freely through the full operating angle of your driveshaft before the vehicle is lowered off the lift.
