Nimraynn Posted August 7, 2015 Report Share Posted August 7, 2015 Hi guys, Bit of a hard one to describe, but having what I think might be an issue with my 323Ci. If I'm driving with a heavy right foot, I get a vibration from the rear... but only when I hit 4k RPM in 2nd gear. If I take my foot off the pedal and let it coast, the vibration goes away, but if I put my foot back in it, it starts vibrating again. It feels like it's coming from the rear passenger side. Same RPM in 1st or 3rd gear causes no issues, purely in 2nd gear. Any ideas what this could be? Cheers, Mike Quote Link to comment Share on other sites More sharing options...
Rob- Posted August 7, 2015 Report Share Posted August 7, 2015 Prop shaft centre bearing or the rubber coupling/guibo would be the first thing to check. On the earlier cars the subframe mounts can tear away from the boot floor but thats more of a clunk than a vibration. Quote Link to comment Share on other sites More sharing options...
Nimraynn Posted August 7, 2015 Author Report Share Posted August 7, 2015 Are these easy things I could check on the driveway? Or better getting a pro to check them? They sound like something I'd get a pro to change, but if I could at least check it myself, that'd be good. Quote Link to comment Share on other sites More sharing options...
Rob- Posted August 7, 2015 Report Share Posted August 7, 2015 Probably best to check with the car off the ground. Quote Link to comment Share on other sites More sharing options...
Jay. Posted August 7, 2015 Report Share Posted August 7, 2015 as above it'll be the guibbo / possibly diff rear bush Quote Link to comment Share on other sites More sharing options...
mjn Posted August 7, 2015 Report Share Posted August 7, 2015 Perished bushes i'd say. With these cars being over 10 years old, all the rubber bits are coming to end of their life really. Quote Link to comment Share on other sites More sharing options...
Nimraynn Posted September 7, 2015 Author Report Share Posted September 7, 2015 So it kinda got progressively better to the point it almost went away.. then today it went bang and now it's vibrating and banging its way through second gear, even doing it in 1st and 3rd as well now How driveable is it going to be if I baby it? Cause a lot of damage or be OK? And how much should I be looking at for it to be fixed? Quote Link to comment Share on other sites More sharing options...
bungers Posted September 7, 2015 Report Share Posted September 7, 2015 Should be ok coasting it about, couple of hundred for parts & labour I'd say. Quote Link to comment Share on other sites More sharing options...
Nimraynn Posted September 8, 2015 Author Report Share Posted September 8, 2015 Ok cheers. I found out my Dad was having his mechanic mate do some work on his car today so I asked nicely if he could have a quick look at the same time. Left the car at home for him to look at so will find out when I get home what needs to be done, but it does sound like the diagnosis here is spot on. I was expecting that sort of money, but I don't have a couple hundred quid spare at the moment Will have to see what he quotes and see what I can do. May be a case of borrow the dreaded Mini every day I can and baby it every day I can't until pay day Quote Link to comment Share on other sites More sharing options...
