PRECAUTIONS
PRECAUTIONS PFP:00001 Precautions AES0000C
● When installing rubber parts, fin al tightening must be carrie d out under unladen condition * with tires on
ground. 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.
● After installing removed suspension parts, check wheel alignm ent and adjust if necessary.
● Lock nuts are unreusable parts; always use new ones. When replacing, do not wipe oil off new lock nut
before tightening.
● Use flare nut wrench when removing or installing brake lines.
● Always torque brake lines when installing.

WARNING:
● Always perform following procedure on a flat surface.
● Make sure that no person is in front of v eh icl e before push-
ing it.
1. Bounce rear of vehicle up and down to stabilize the posture.
2. Push vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires at
the same height of hub center. This mark is a measuring point.
4. Measure distance “A” (rear side).

5. Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn).
If wheels have rotated more than 180 degrees (1/2 turn), try the
above procedure again from the beginning. Never push vehicle
backward.
6. Measure distan ce “B” (front side).
Total toe-in : Refer to RSU-16, "SERVICE DATA" .
7. Adjust toe-in b y turning adjusting bolts.
Toe changes about 1.5 mm (0.059 in) [One side] with each graduation of adjusting bolt.
CAUTION:
Be sure to adjust equally on RH and LH side with a djusting
bolt.
8. Tighten to the specified torque.
