torque is proper (350-400 lbf-ft (475-545
Nm)). Ensure that the stud is clean and not
stripped (upper side).
2. Install new rubber (mounting) bushing on
shock absorber (upper side).
3. Place the inner washer on shock absorber
pin (Fig. 33).

and the shock absorber eyes over the
mounting pins. Install the outer washer.
6. Place a rubber joint and washer on the
shock absorber mounting stud. Place the
lower shock absorber mounting stud nut and
torque to 40-50 lbf-ft (55–70 Nm).
7. Place the upper mounting pin stud nut and
torque to 70-85 lbf-ft (95–115 Nm).
3.19 SWAY BAR

NOTE
Sway bar bushings are slit to ease their
removal.
3.19.2 Installation
1. Loosely install the sway bar.
2. Torque bushing collar nuts to 60 lbf-ft (82
Nm).
3. Torque sway bar link upper nuts to 120-140
lbf-ft (163-190 Nm) on front suspension and
to 100-120 lbf-ft (136-163 Nm) on rear
suspension.
4. Torque sway bar link lower nuts to 120-140
lbf-ft (163-190 Nm) on front suspension and
