hushmana 0 Report post Posted April 10, 2006 After getting an Air duct under the manifold, siliconed back into place, costing me $180 (ripped off) my Bimmer has decided it wants to be sick again. Driving home from work last week I noticed a banging sound coming from the left hand side rear wheel area. The sound only occurs when I go over the slightest of bumps. It sounds similar to something hitting the bottom of the car. Last July I had new shocks and super low king springs installed so I’m thinking that it can’t be related to those two things. I have read some passed postings and suggestions have been the • Sway Bar • Strut Top • Possibly the Control Arm Joint • The lower ball joints. I’m not at all mechanically savvy, so I wouldn’t even know if any of these are causative. If any one has any ideas before I put her into the shop, would really appreciate it. Thanks Mana.

topless 13 Report post Posted April 10, 2006 check upper and lower shock mounts, bolt/nut may be loose or rubber bush may be damaged. Not the exhaust banging against anything? Quote Share this post Link to post Share on other sites
hushmana 0 Report post Posted April 10, 2006 Hey, how can I tell if the lower and upper shock mounts are loose as well as whether or not the rubber bush is damaged? The exhaust is tight and so are the wheel bolts. Cheers Quote Share this post Link to post Share on other sites
