Okay well this is something driving me completely nuts. I have a 2008 VE Commodore. Just recently had back shocks replaced and bump stops. All is good for the rear. The front also got replaced strut top mounts, though since then my cars front suspension doesn't sound right. Since I got the strut top mounts replaced, I have a very light knocking noise on left hand side when coming on & off a gutter (Bump/Driveway) now and then. Now I'm hearing on drivers side front, when going over continuous bumpy roads, I hear a continious knocking sound like someone tapping the outside of my car with something metal (not the best explanation) none of these noises where there before strut top mounts replaced. (THE NOISES ARENT ABSOLUTELY, JUST ENOUGH TO HEAR) Took back to mechanic and told him my concern, he said it's because I don't have too much to work with since my car is fully lowered all the way round. And it's true my car is very low, often scratch on the smallest of speed bumps when I'm not careful!!!! I'm thinking of changing back to regular springs if this helps the car take more. The car was bought fully lowered. I didn't realise when I bought the car just how low it sits. Whats everyone's thoughts? (Replacements done 4 weeks ago/wheel alignment done) - could it be anything like top strut nut loose?
