All trucks have lubrication grease fittings at various locations within the steering and front suspension. These fittings should be lubricated with every oil change and after any off-pavement driving in water or sand. You'll need a grease gun filled with Multipurpose grease SAE J310 (NLGI No. 2) and a large rag. Inexpensive grease guns are available almost everywhere and the newer styles use grease cartridges which eliminate the mess of loading the grease into the gun.
- Raise and safely support the vehicle on jackstands. Ramps can be used, but access is easier when the suspension hangs down.
- Locate each grease nipple and wipe it clean of dust and grime. Fit the grease gun end onto each nipple. Apply just enough grease into the fitting to fill the dust seal - but not until it comes out of the dust seal covering the joint.
- Remove the gun from the fitting and use the rag to wipe away excess grease at the fitting.
- Continue with each fitting. Depending on the year and model, grease fittings may be found on the lower ball joint and steering joint (left and right), the upper ball joint (left and right), the tie rod ends (left and right) and the pivot for the pitman (steering) arm. Additionally, some trucks have fittings at both ends of the driveshaft running to the rear wheels.
- Lower the vehicle to the ground.
Vehiles which are driven through water should be subjected to inspection of the following components. If you are planning on taking your 4WD vehicle into a stream make sure that you seal up the speedometer cable with water-resistant grease or tape. Inspect all the dust boots and the breather hose for cracks or damages, replace if necessary.
