Front driveshaft lubrication (2500/3500 4WD)
(every 6,000 miles or 6 months)
1. Raise the vehicle and support it securely on jackstands. Clean the grease fitting on the front driveshaft with a rag.
2. Use a conventional grease gun to apply sufficient lubricant to the fitting. Don’t apply so much that an excessive amount comes out.
3. Wipe any extra grease and dirt from the area with a rag.
