Universal joints maintain a smooth rotational transition through an allowable angle variation during normal vehicle operation. The acceleration and deceleration of the driveshaft is controlled by needle bearings found in the universal joint cup.
Universal joints have:
- a lubed-for-life design.
- nylon thrust washers, located at each base of the bearing cup, which control end play, position the needle bearings and improve grease movement.
- 1350 series universal joints (standard) with a 92.07 mm (3-5/8 in) span (span measurements are with bearing cups fully seated on the spider) and 30.18 mm (1-3/16 in) bearing cups.
- snap rings that fit into grooves in the universal joint housing for accurate alignment of the spider and the center of the driveshaft tube.
