Chrysler Full-Size Trucks 1967-1988 Repair Guide

Chassis Greasing

Print

See Figures 1, 2 and 3

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) conforming to Mopar specification NLGI Grade 2 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 truck, must be greased. Most trucks covered in this guide should be equipped with grease nipples on the ball joints, although some may have plugs which must be removed and nipples fitted. These nipples can be obtained through your local parts distributor.


WARNING
Do not pump so much grease into the ball joint that excess grease squeezes out of the rubber boot. This destroys the watertight seal.

Jack up the front end of the truck and safely support it with jackstands. Block the rear wheels and firmly apply the parking brake. If the truck has been parked in temperatures below 20°F 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 now have the ends of the upper and lower suspension control arms in front of you; the grease nipples are visible pointing up (top ball joint) and down (lower ball joint) through the end of each control arm. If the nipples are not accessible, remove the wheel and tire. Wipe all dirt and crud from the nipples or from around the plugs (if installed). If plugs are on the truck, 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, lubricate the ball joint only until the rubber joint boot begins to swell out. DO NOT OVER GREASE!

STEERING LINKAGE



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 and crud from around the nipples at each tie rod end. Using a hand operated, low pressure grease gun loaded with a suitable chassis grease, lubricate the linkage until the old grease begins to squeeze out around the tie rod ends. Wipe off the nipples and any excess grease. Also lubricate the nipples on the steering idler arms.

PARKING BRAKE LINKAGE



See Figures 4, 5 and 6

Use chassis grease on the parking brake cable where it contacts the cable guides, levers and linkage.
