Before you go buying parts though, I'd get under the car and check for myself to ensure that I was replacing the right arm (there are three at the back)

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi All I had this item on my last MOT on the Boxster and wondered if anyone knew exactly what the issue is and what part I need to have replaced? "Offside Rear Suspension arm pin or bush worn but not resulting in excessive movement lower arm, inner bush (5.3.4 (a) (i))" Many Thanks Simon

POST 2Original post

At a guess it is the rear coffin arm (lower arm) with either a knackered ball joint or possibly a deteriorated rubber bush. Either way, you replace the whole arm so both of those issues would be fixed in the same way. Before you go buying parts though, I'd get under the car and check for myself to ensure that I was replacing the right arm (there are three at the back)

POST 3 / ORIGINAL POSTEROriginal post

Thanks Lenny, appreciate the advice. Was intending to get under there and see what I can find, or failing that it finally dawned on me to take it back to the MOT centre and get them to point to what the issue is! :-)
