Description
UJ68745UL universal joint, 68745 series, 2.047″ cap diameter x 5.795″ cross width, greaseable design.
Full Description
Selecting the correct universal joint requires matching three critical dimensions: series, cap diameter, and cross width. The UJ68745UL checks all three for 68745 series driveshafts: 2.047" caps and 5.795" overall width. This guide walks through the specifications and installation considerations for this joint.
Series and Cap Diameter Explained
The 68745 series designation defines the torque capacity tier for this joint. At 2.047", the bearing cap diameter governs the contact area between cross trunnion and needle bearings -- a direct indicator of load capacity. Larger cap diameters handle greater torsional loads and are typically found on heavier trucks and industrial equipment. The UJ68745UL is sized for 68745 series yokes and should not be substituted with a different cap diameter even if the overall cross width appears similar.

Material and Heat Treatment
Universal joint crosses for driveshaft use are manufactured from case-hardened alloy steel. The hardened surface resists abrasion from needle bearings while the tough core absorbs shock loads. The UJ68745UL cross meets this standard, with a surface hardness that supports the full torque rating of the 68745 series.
Step-by-Step Replacement
- Remove driveshaft: unplug from transmission slip yoke and companion flange
- Use a 2-jaw puller or press to extract old bearing cups from yoke ears
- Deburr and clean all four yoke bores
- Install UJ68745UL cross: start two opposing cups, then complete the remaining pair
- Press each cup to snap ring depth without damaging needle bearings
- Verify smooth articulation through at least 30 degrees in all planes
