Oil will shorten the life of rubber bushes. Be sure to wipe
off any spilled oil.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
I
Use flare nut wrench when removing or installing brake
tubes.
I
After installing removed suspension parts, check wheel
alignment.
I
Do not jack up at the trailing arm and lateral link.
I
Always torque brake lines when installing.

Lock nuts are unreusable parts; always use new ones.
When replacing, do not wipe the oil off of the new lock nut
before tightening.
