S10/T10 Blazer 4WD V6-4.3L VIN W (1997)
Inspect
1. The retaining ring grooves for plastic.
2. The bearing cup bores for burrs or imperfections.
Clean
-
The remains of the sheared plastic bearing retainers from the grooves in the yoke.
-
The sheared plastic may prevent the bearing cups from being pressed into place and thus prevent the bearing retainers from being properly
seated.
ASSEMBLE
-
Remove the bearing cups from the universal joint and use your finger to coat the needle bearings in the bearing cup with a thin layer of grease.
1. One bearing cup part way into one side of the yoke.
-
Turn the yoke ear towards the bottom.
2. Cross into the yoke so that the trunnion seats freely into the bearing cup.
-
With the trunnion seated in the bearing cup press the bearing cup into the yoke until it is flush with the yoke ear.
3. The opposite bearing cup part way into the yoke ear.
-
Make sure that the trunnions are started straight and true into both bearing cups.
-
Press the opposite bearing cup into the yoke ear while working the cross all the time to check for free unbinding movement of the trunnions in
the bearing cups.
-
Press the bearing cup into the yoke until the bearing retainer groove clears the inside of the yoke.
Important: If there seems to be a hang-up or binding, stop pressing, and check the needle bearings for misalignment in the bearing cup.
