  4. Inspect the front shock absorber for oil leakage and if there is any malfunction, replace the front shock absorber. (See FRONT SHOCK ABSORBER AND COIL SPRING REMOVAL/INSTALLATION .) (See FRONT SHOCK ABSORBER AND COIL SPRING DISASSEMBLY/ASSEMBLY (US) .)
    CAUTION:
    • Even if there is no oil leakage, there may be gas leakage or internal part damage. Gas leakage and internal part damage cause a lowered vehicle height, unstable vehicle movement, or abnormal noise. Perform the stroke inspection and verify that there is no malfunction.

      NOTE:
      • The oil stain is not progressive because the area dampens and dries repeatedly.
