SUSPENSION 4-1
Take out the coil spring, using care not to cause the spring to
contact the strut rod.
INSPECTION
Check the disassembled parts for cracks, damage and wear, and
replace with new parts if defective.
Damper strut
1) Check for oil leakage.
2) Move the piston rod up and down to check its smooth
operation without any binding.
3) Deflection of piston rod
Measure the deflection as follows:
Fix the outer shell and fully extend the rod. Set a dial gauge
at the end of the rod, and apply a weight of ±20 N (±2 kg,
±4 Ib) to the threaded portion. Read the dial gauge indication.
The amplitude of the gauge needle pointer is the deflection of
the rod.
Limit of deflection:
Less than 0.8 mm (0.031 in)
If the deflection is greater, replace the strut.

Strut mount
1) Check rubber part for creep, cracks and deterioration, and
replace it with new one if defective.
2) If distortion is found on its connecting surface to body,
replace it with a new one.
Dust cover
If any cracks or damage are found, replace it with a new one.

Coil spring
One having permanent strain should be replaced with a new
one. When vehicle posture is uneven, although there are no
considerable reasons like tire puncture, uneven loading, etc.,
check coil spring for its free length, cracks, etc., referring to
specifications, and replace it with a new one if defective.
Helper
Replace it with new one if cracked or damaged.
ASSEMBLY
1) Compress the coil spring with COIL SPRING COMPRES·
SOR (926110000).
Make sure that the vertical installing direction of coil spring is
as shown below.
