On-vehicle Inspection
1. Check the front shock absorber assembly.
a. Park vehicle on level ground, and bounce the vehicle up and down, then check if vehicle shakes up and
down when body bounds. If vehicle shakes up and down consecutively, shock absorber assembly may
be damaged and should be replaced.
2. Check the front shock absorber assembly for leakage.
a. As shock absorber assembly operates frequently while driving vehicle, shock absorber fluid
temperature rises and oil gas is formed and adheres to dust boot. This is a normal phenomenon, and it
is not necessary to replace the shock absorber assembly.
b. Shock absorber is designed with a thin layer of oil film on surface of piston rod. While the shock
absorber is being compressed, the oil film will be scraped off by dust plate on shock absorber oil seal
and a small amount of oil will remain on the upper part of oil seal. Due to high oil permeability, oil
deposited on the upper part of oil seal spreads slowly from the upper part of shock absorber to lower
part of shock absorber, thus forming a thin coat of oil film. When any of following conditions occurs:
- Oil film is between dust boot and spring seat;
- Oil traces in circumferential direction are even.
- For above conditions, oil traces are formed through volatilization, so we can judge it as minor leaks.
This is a normal phenomenon, and it is not necessary to replace the shock absorber assembly.
c. If following conditions occur:
- Oil traces in circumferential direction are uneven;
- Oil traces reach lower connecting positions.
- Above conditions indicate that there may be leakage in shock absorber assembly, and it is
necessary to replace the shock absorber assembly.
d. If it is difficult to accurately judge shock absorber assembly for leakage from appearance. Perform road
test after wiping off oil on the surface of malfunctioning shock absorber. Under normal road conditions,
drive vehicle for 5 to 10 minutes and perform inspection. If there are oil traces at the shock absorber
assembly surface, it indicates oil leakage, and it is necessary to replace the shock absorber assembly.
Removal
WARNING
 Be sure to wear necessary safety equipment to prevent accidents.
 Make sure that safety lock of lifter has been locked when removing and installing chassis parts.
 It is not permitted to weld or modify suspension bearing parts and guide parts.
 When removing and installing chassis parts, replace self-locking nuts and rusted nuts for safety.
 Operate carefully when removing and installing coil spring, preventing spring from jumping out and
causing personal injury.
HINT:
 Use the same procedures for the right side and left side.
 Procedures listed below are for the left side.
1. Remove the front left wheel
2. Remove the front left shock absorber assembly.
