PRECAUTIONS
Revision: 2006 January2006 M35/M45
PRECAUTIONSPFP:00001
PrecautionsNES000J2
When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
–Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
After servicing suspension parts, be sure to check wheel alignment.
Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-
oiled, tighten as they are.

SHOCK ABSORBER
Revision: 2006 January2006 M35/M45
SHOCK ABSORBERPFP:56210
Removal and InstallationNES000JA
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Set a jack under rear lower link to relieve the coil spring tension.
3. Remove shock absorber lower end bolt with a power tool.
4. Gradually lower the jack to remove it from rear lower link.
5. Remove shock absorber assembly upper end nuts with a power
tool, and then remove shock absorber assembly from vehicle.
INSPECTION AFTER REMOVAL
Check shock absorber assembly for deformation, cracks, damage, and replace if there are.
Check welded and sealed areas for oil leakage, and replace if there are.
INSTALLATION
Installation is the reverse order of removal. For tightening torque. Refer to RSU-7, "Components" .
CAUTION:
Do not reuse non-reusable parts.
Perform final tightening of shock absorber assembly lower side (rubber bushing) under unladen condition
with tires on level ground. Check wheel alignment. Refer to RSU-5, "
Wheel Alignment Inspection" .
Adjust neutral position of steering angle sensor after checking the wheel alignment. Refer to BRC-6,
"Adjustment of Steering Angle Sensor Neutral Position" .
Disassembly and AssemblyNES000JB
DISASSEMBLY
CAUTION:
Make sure piston rod on shock absorber is not damaged when removing components from shock
absorber.
1. Remove mounting seal from mounting bracket.
2. Wrap a shop cloth around lower side of shock absorber and secure it in a vise.
CAUTION:
Do not set the cylindrical part of shock absorber in a vise.
3. Secure the piston rod tip so that piston rod does not turn, and
remove piston rod lock nut.
4. Remove washer, distance tube, bushing, bound bumper cover
and bound bumper from shock absorber.
INSPECTION AFTER DISASSEMBLY
Bound Bumper and Bushing
Check bound bumper cover and bushing for cracks and damage. Replace if there are.
