340 MAINTAINING YOUR VEHICLE Front Suspension Ball Joints The ball joints originally supplied with the vehicle are permanently lubricated at the factory and do not require service. The ball joints and seals should be inspected whenever the vehicle is serviced for other reasons. Steering Linkage - Inspection Whenever the vehicle is hoisted, all steering linkage joints should be inspected for evidence of damage. If seals are damaged, parts should be replaced to prevent leakage or contamination of the grease. Front Axle Universal Drive Joints And Pivot Bearings The front axle universal joint and pivot bearings are permanently lubricated and do not require servicing. Body Lubrication Locks and all body pivot points, including such items as seat tracks, doors,liftgate and hood hinges, should be lubricated periodically to assure quiet, easy operation and to protect against rust and wear. Prior to the application of any lubricant, the parts concerned should be wiped clean to remove dust and grit; after lubricating excess oil and grease should be removed. Particular attention should also be given to hood latching components to insure proper function. When performing other underhood services, the hood latch, release mechanism and safety catch should be cleaned and lubricated. The external lock cylinders should be lubricated twice a year, preferably in the fall and spring. Apply a small amount of a high quality lubricant such as Mopar௡ Lock Cylinder Lubricant directly into the lock cylinder.
