Precautions for Suspension

INFOID:0000000003130373

CAUTION:

• When installing rubber bushings, the final tightening must be carried out under unladen conditions

with tires on ground. Oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.

- Unladen conditions mean 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.
• Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are

pre-oiled, tighten as they are.
