FRONT SUSPENSION

WHEEL ALIGNMENT

7. THRUST ANGLE

• Inspection

1) Position vehicle on a level surface.
2) Move vehicle 3 to 4 meters (10 to 13 ft) directly
forward.
3) Determine locus of both front and rear axles.
4) Measure distance “L” between center line of loci
of the axles.

Thrust angle:

Less than 30

′′′′

when “L” is equal to or less

than 23 mm (0.91 in).

• Adjustment

1) Make thrust angle adjustments by turning toe-in
adjusting bolts of rear suspension equally in the
same direction.
2) When one rear wheel is adjusted in a toe-in di-
rection, adjust the other rear wheel equally in toe-
out direction, in order to make thrust angle adjust-
ment.
3) When left and right adjusting bolts are turned in-
crementally by one graduation in the same direc-
tion, the thrust angle will change approximately 10

′

[“L” is almost equal to 7.5 mm (0.295 in)].

NOTE:
Thrust angle refers to a mean value of left and right
rear wheel toe angles in relation to vehicle body
center line. Vehicle is driven straight in the thrust
angle direction while swinging in the oblique direc-
tion depending on the degree of the mean thrust
angle.

FRONT TRANSVERSE LINK

3. Front Transverse Link

A: REMOVAL

1) Set vehicle on a lift.
2) Disconnect ground cable from battery.
3) Lift-up the vehicle and remove the wheel.
4) Disconnect stabilizer link from transverse link.
5) Remove bolt securing ball joint of transverse link
to housing.

6) Remove nut (do not remove bolt.) securing
transverse link to crossmember.
7) Remove two bolts securing bushing bracket of
transverse link to vehicle body at rear bushing loca-
tion.

8) Extract ball joint from housing.
9) Remove bolt securing transverse link to cross-
member and extract transverse link from cross-
member.

B: INSTALLATION

1) Temporarily tighten the two bolts used to secure
rear bushing of the transverse link to body.

NOTE:
These bolts should be tightened to such an extent
that they can still move back and forth in the oblong
shaped hole in the bracket (which holds the bush-
ing).
2) Install bolts used to connect transverse link to
crossmember and temporarily tighten with nut.

CAUTION:
Discard loosened self-locking nut and replace
with a new one.
3) Insert ball joint into housing.
4) Connect stabilizer link to transverse link, and
temporarily tighten bolts.

CAUTION:
Discard loosened self-locking nut and replace
with a new one.

5) Tighten the following points in the order shown
below when wheels are in full contact with the
ground and vehicle is at curb weight.

(1) Transverse link and stabilizer

Tightening torque:

30 N·m (3.1 kgf-m, 22 ft-lb)

(2) Transverse link and crossmember

Tightening torque:

100 N·m (10.2 kgf-m, 74 ft-lb)

(3) Transverse link rear bushing and body

Tightening torque:

245 N·m (25 kgf-m, 181 ft-lb)

FRONT TRANSVERSE LINK

NOTE:
• Move rear bushing back and forth until trans-
verse link-to-rear bushing clearance is established
(as indicated in figure.) before tightening.
• Check wheel alignment and adjust if necessary.

C: DISASSEMBLY

1. FRONT BUSHING

Using ST, press front bushing out of place.

SET

2. REAR BUSHING

1) Scribe an aligning mark on transverse link and
rear bushing.
2) Loosen nut and remove rear bushing.

D: ASSEMBLY

1. FRONT BUSHING

To reassemble, reverse disassembly procedures.

CAUTION:
Install front bushing in correct direction, as
shown in figure.

2. REAR BUSHING

1) Install rear bushing to transverse link and align
aligning marks scribed on the two.
2) Tighten self-locking nut.

CAUTION:
• Discard loosened self-locking nut and re-
place with a new one.
• While holding rear bushing so as not to
change position of aligning marks, tighten self-
locking nut.

Tightening torque:

186 N·m (19.0 kgf-m, 137 ft-lb)

E: INSPECTION

1) Check transverse link for wear, damage and
cracks, and correct or replace if defective.
2) Check bushings for cracks, fatigue or damage.
3) Check rear bushing for oil leaks.
