Hey guys,
I'm having an issue with clunking in the rear after the install of solid aluminum Turner rear subframe bushings. I had a local indy shop to do the install as I don't have a press and I knew I wouldn't be able to do it myself. It was good for a bit but after the first few weeks I noticed a clunking sound which I'm pretty sure is due to the solid subframe bushings. Everything else in the rear end has been upgraded over the last couple of years.
Has anyone else experienced this? I did a fair amount of research before deciding to go solid as this car is my daily driver and I didn't want a drastic increase in NVH, but didn't see anything about clunking. My indy told me he's seen it in E9X M3's previously. Pretty much all the other mounts and bushing in the car have have been upgraded, but none of those were solid because it seemed like they would all cause NVH issues wehere people with solid subframe bushings said that wasn't the case, and that's also the place where they make the biggest difference in performance. It tightened up the rear end considerably and if it did increase NVH, it didn't do so by much, but I don't want to live with the clunking from the subframe. Does anyone have any suggestions that might help? I'd like to fix it if possible, but if I can't I will have them pulled and replace them with something different.
