So I have been having a problem with my car pulling, oddly in both directions. I have had the car aligned THREE times now. Originally right before I left for FL, I had the dealer do it. They also told me to replace a rear control arm and both front control bushings on the front before I had it aligned. Previously I had also replaced the driver's side ball joint. (The ball joint replacement was what threw it off.)
1) the dealer did a horrible job
2) I replaced my passenger side ball joint as it was horrible and I had it aligned at the shop I work at, however we are not set up for BMW's and didn't use weights. Would have thought the dealer would have mentioned that ball joint... this was 6,000 miles after initial alignment
3) The alignment tech and myself used me sitting in the back seat in the middle leaned forward to align the car. (Figured I've got nothing to lose except another $140 at the dealer so I'll try it!)
The car actually drives MUCH MUCH better since this last alignment. However, if I let go of the steering wheel, in not too long of a time it will pull the right.... then maybe to the left.... then maybe to the right.... it will eventually pick a side and head for the ditch tho.
Bad tie rods?? Everything under there seems tight. I don't think the weights could have this significant of a difference...? Rear struts sound like they need replacing... idk if these would have an effect on it... Thanks
