INSPECTION

1 Check suspension arm for deformation or damage.

2 Check suspension shaft for deformation or damage.

3 Check dust cover for damage.

4 Check shock absorbers for malfunction, oil leakage or noise.

5 Check coil springs for deterioration, cracks or damage.

6 Check spring seats and bump stoppers for damage.

7 Check stabilizer bar for damage.

DISASSEMBLY

1 Before the fixtures are removed, make alignment marks of the

fixtures and suspension arms for reference at reassembly.

2 Loosen the nuts at both ends of the suspension arm to remove

the fixtures and rubber bushings.

3 Before rear suspension on cars with rear stabilizer bar is disas-sembed, put aligning marks on each end of stabilizer bar in alignment with the punch mark on the stabilizer bar bracket Then, while the rear suspension is separated into the right and left arms, remove the stabilizer from the bracket.

4 Remove the dust cover clamp.

5 Separate the suspension arm into the right and left arms leave the dust cover attached to the right suspension arm to protect the lip from damage.

6 Remove the rubber stopper from the right arm.

8 Using a hammer and drift, drive the bushing B out of left sus-pension arm.

REASSEMBLY

1 Apply the specified grease to the inside of the left suspension

2 Using Special Tools, Installer Attachment (09555-21100) and Bar (09555-21000), drive bushings B and A in that order into the suspension arm.

CAUTION

(a) Apply grease to all outside surfaces of bushings B and A (b) Drive the bushing B in until the notch on the Special Tool (09555-21000) reaches the end of the suspension arm.
