Condition



Some customers may comment on a clunk or thump noise coming from the front suspension while driving over rough road surfaces. This noise will



typically occur when the front suspension is returning to the upward position after a hard downward stroke, such as after driving through a large rut



or pothole.



Cause



This condition may be caused by the jounce bumper slamming into the upper spring seat because it is not retained in the correct up position. The



jounce bumper loses position due to oil being deposited onto its retention fingers. The oil is from the strut leaking.



Correction



Inspect the front strut(s) for evidence of oil. The leak may be slight but will still cause the concern. If oil is present, replace the affected strut, jounce



bumper and dust boot (shield). Before reassembling the strut assembly, glue the new jounce bumper and new dust boot (shield) to the upper spring



seat using the steps listed below. To further confirm this concern, the shield/bumper will easily slide up and down the strut shaft.
