PRECAUTIONS
Revision: 2005 July 2005 FX
PRECAUTIONSPFP:00001
CautionAES000MZ

When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on ground. Oil will 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.

Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.

Avoid burden to front cross bar.
