Subframe Bushings help.

Im pretty sure the bushings need to be replaced because i hear the clunk noise when shifting at low speeds. I know usually with this the subframe causes cracks, but i dont hear any of the noises associated with a crack. could it be i only need the bushings and not welding, or does bad bushings always mean there is a crack?
Thanks
Vas

You are positive that clinking is from the subframe? Sounds like the famous M clunk from what you said.

I hope it's the famous m clunk but it is happening very often. There is also the famous M subframe crack which can cost 2k to fix. (God I hope not lol)

Bushings are pretty robust and would not causing a clunking sound. A severe crack or tear in the bodywork that the sub-frame attaches to will make noise. All things considered, sub-frame issue are very rare unless that car has a bunch of weight in the trunk (stereo equipment) or it was abused (burn outs, crappy roads, etc.)

Yeah you'll want to get in there and physically check everything to see what the issues are. If it does end up being the bushings though, you'll know where to get them!


PowerFlex Urethane Suspension Bushings E46 Non-M/M3

I hope that helps! Let me know if there's anything else I can do for you.

You cannot diagnose bushings by sound.

Put it up on a lift and inspect them.
