CAUTION:

• Do not depress the brake pedal when measuring.

• Do not perform this inspection with the tires on the ground.

• Be careful not to damage ball joint boot. Do not damage the components by applying excessive force.

Oil Leakage Inspection

• If oil (A) does not extend beyond the spring seat (B) or upper half (C) of strut/shock absorber (1), this is slight oil seepage and the strut/shock absorber should not be replaced.

  

• If oil (A) does extend beyond the spring seat (B) or upper half (C) of strut/shock absorber (1) as shown, perform the following.

  

  • Use a finger to touch the oil that has extended beyond the spring seat or upper half of strut/ shock absorber.

    • If the oil layer is thick and contains large pieces of dust and debris, replace the strut/shock absorber.

    • If the oil layer is thin and does not contain large pieces of dust and debris, do not replace the strut/shock absorber.

Note:

If strut/shock absorber leakage is diagnosed in one strut/shock absorber, do not automatically replace both sides. Replace only the leaking strut/shock absorber.
