• When installing rubber bushings, final tightening must be carried out under unladen conditions with tires on
level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
 Unladen conditions means that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
 After servicing suspension parts, be sure to check wheel alignment.
 Caulking nuts are not reusable. Always use new ones w hen installing. Since new caulking nuts are pre-oiled,
tighten as they are.
