REAR BUSHING

  1. Install the rear bushing to transverse link and align aligning marks scribed on the two.
  2. Tighten a new self-locking nut. NOTE: While holding the rear bushing so as not to change position of aligning marks, tighten the self-locking nut. Tightening torque: 190 N.m (19.4 kgf-m, 140 ft-lb)

STRUT MOUNT

Check the rubber part for creep, cracks and deterioration, and replace it with a new one if defective.

DUST COVER

If any cracks or damage are found, replace it with a new one.

COIL SPRING

Coil spring having permanent strain should be replaced with a new one. When the vehicle posture is uneven, although there is no considerable reasons like tire puncture, uneven loading, etc., check the wheel arch height referring to specifications and replace the coil spring with a new one if the measured value is out of specification.

HELPER

Replace it with a new one if cracked or damaged.

DISPOSAL

CAUTIONBefore handling gas filled struts, be sure to wear goggles to protect eyes from gas, oil or filings. Do not disassemble the strut damper or place into a fire. Drill holes before disposing of gas filled struts.

Scheme 51
