Question about alignment issues
So I went to get an alignment and the guy said that he adjusted it as much as he could. He said something about an "eccentric" or some rubber bushing/mount that may be worn and preventing him from adjusting the camber/toe/caster anymore. Can anyone shed some light on this? I'm posting a picture which I would think includes the part he's talking about. Can anyone point to the number in the diagram below? Thanks!

Since you posted drawing of the rear Im guessing he at least told you the problem is with the rear setup.
Ask if the rear trailing arm bushings (#4 in your pic) are worn out (RTABs). This is the most likely culprit. If so they have to be replaced. If you have some mech ability and the proper tools (Search DIY RTAB here or on the E46 Fanatic forum) this is not impossible to do yourself - but if not... its gotta get done. http://www.zpost.com/forums/showthread.php?t=673800 Unless you track or just want the car much tighter (and rougher) I'd go with a rubber bushing Parts: ECS : http://www.ecstuning.com/BMW-Z4-3.0i...g_Arm/ES57714/ or http://www.vorshlag.com/product_info...products_id=59 Good Luck Last edited by BruceJ; 07-07-2012 at 12:11 AM.. |

Sure. I just had a regular 4 wheel alignment because I just went from a 17" square setup to an 18" staggered setup with a different offset and tire size in the rear. Passenger side rear tire had one tread barely off the ground. Driver's side had all treads evenly on the ground. 72k miles on the chassis. It's a 10 year old car (Sept 2002 production). I figure the rubber bushings are starting to go. I've already had to change the FCA's, FCAB's, and FSM's because the rubber in those parts had deteriorated pretty badly. |
