See Figure 1
The lubrication chart indicates where the grease fittings are located. The vehicle should be greased according to the intervals in the Preventive Maintenance Schedule at the end of this section.
Water resistant EP chassis lubricant (grease) should be used for all chassis grease points.
Every year or 7,500 miles (12,000 km), the front suspension ball joints, both upper and lower on each side of the vehicle, must be greased. Many vehicles covered in this guide are equipped with grease nipples on the ball joints, although some may have plugs which must be removed and nipples fitted. Some late model vehicles have lifetime lubricated chassis components which cannot be serviced.
Jack up the front end of the vehicle and safely support it with jackstands. Block the rear wheels and firmly apply the parking brake. If the vehicle has been parked in temperatures below 20°F (-7°C) for any length of time, park it in a heated garage for an hour or so until the ball joints loosen up enough to accept the grease.
Depending on which front wheel you work on first, turn the wheel and tire outward, either full-lock right or full-lock left. You will then have the ends of the upper and lower suspension control arms in front of you, with the grease nipples visible. The upper ball joint nipples point up (top ball joint) and the lower ball joint nipples point down, through the end of each control arm. If the nipples are not accessible enough, remove the wheel and tire. Wipe all debris from the nipples or from around the plugs (if installed). If plugs are on the vehicle, remove them and install grease nipples in the holes (nipples are available in various thread sizes at most auto parts stores). Using a hand operated, low pressure grease gun loaded with a quality chassis grease, grease the ball joint only until the rubber joint boot begins to swell out.
See Figures 2 and 3
The steering linkage should be greased at the same interval as the ball joints. Grease nipples are installed on the steering tie rod ends on most models. Wipe all dirt from around the fittings at each tie rod end. Using a hand operated, low pressure grease gun loaded with a suitable chassis grease, grease the linkage until the old grease begins to squeeze out around the tie rod ends. Wipe off the nipples and any excess grease. Also grease the nipples on the steering idler arms.
DRIVESHAFTS & UNIVERSAL JOINTS
See Figures 4 and 5
Use chassis grease on the front (4x4 only) and rear driveshafts and all drivehshaft universal joints.
PARKING BRAKE LINKAGE
Use chassis grease on the parking brake cable where it contacts the cable guides, levers and linkage.
AUTOMATIC TRANSMISSION LINKAGE
Apply a small amount of clean engine oil to the kickdown and shift linkage points at 7,500 mile (12,077 km) intervals.
