From the off l'll tell you l aren't very knowledgeable about cars full stop so those that are will probably talk in a language l'll find hard to follow, but l'll try. I have a 2001 Bugeye Impreza turbo and recently had all of the bushes changed. Up to this point the car had been running great but since then a very loud rattle/vibration occurs which sounds like its coming from underneath somewhere but this only happens when the car is moving and you lift your foot off the gas. You can rev it when idle and not a sound. Any ideas what it could be? Also getting a squeaking noise from the rear when going over bumps. New coilovers fitted a couple of months ago(BC Coilovers). Any help/ideas would be greatly appreciated. Thanks in advance.

 

Hi there, chances are it may be the heat shields and the BC's are common as Mars bars to make noises, they are only cheaply made.

 

I'll have the shields checked and l was afraid you'd say that about the BC's. Had considered going with meister. Going back to garage today so hopefully it will be sorted. Cheers for the help BBB3.

 

This happened to me the other day, only at faster speeds and it was the under tray, just needed clipping back in

 

Sorry for being thick, BC'S?

 

having the same issue, i don't have an undertray anymore so it's not that. also had my wheel bolt nuts replaced because i saw lots of posts on different forums that it fixed the problem (for having noise when lifting of the gas pedal).
car is still as stable as ever in the corners and i see no oil on the shocks so i think they're still OK. took of the wheel and tried to find if anything was lose but nothing budged.

mine is a my00 gc8.

 

Check this I had the same problem.

BC's are the coilover make Steve 001. daddyd like you l have no undertray but did have one until the bushes were changed and then the noise started.Up until changing all the bushes my car was quiet apart from the dashboard/windscreen vibrating. I have had a lot of work done on it lately and up to this point no problems but have been just replacing old for new in some cases, refurbs in others with the odd upgrade, but nothing in the engine department. Bit frustrated that l can't pin point the problem myself, but that's what happens when you try to play mechanics with no knowledge, lol
