Symptoms
Part of dusty-road and towing maintenance. Owners count five zerks on a 4WD truck.
The fix, step by step
- Grease both spider joints on each shaft and the front slip yoke (a couple of short pumps only; over-packing a slip yoke is bad).
- The rear slip yoke is booted with no zerk, so servicing it means dropping the shaft.
- Wipe off excess grease.
Tools & part numbers
- Grease gun
- lithium-base chassis grease
