Have a sedici about 100k on the clock and it has a suspension rattle. Garage cannot find it and it passed its MOT, but on pot holey roads there is a definite knock on the LHS
Any thoughts

I had a similar symptom on my 75k car when I bought it. Turned out to be a front strut that was failing. It only threw the bag of bolts rattle in a specific set of circumstances but credit the supplying dealer who took me at my word and chased the fault down.

A possibility if it's on its originals?
