Hello and Thank you for reading. I have an '03 330xi with 102k miles.
I recently did an entire Suspension Refresh: Struts (Koni Sport), Springs (Eibach), Inner Ball Joints, Upper Strut Tower Bearings, Tie Rods, Control Arms, Spring Pads, Front Sway Bar Bushings (PowerFlex), Strut Tower Reinforcement Plates, Sway Bar Links.
While completing this job, we had one HECK of a time getting one of the Springs to seat correctly on the Strut. We finally got it as good as we could and hoped that it would seat itself while driving...it did not...so, off to the Stealership I went. They attempted to get the Spring to seat and could not. They determined that it was defective so I ordered a new one and this was installed. When I got the car back, it felt better but not as good as I hoped. I then took it to be Aligned and have the wheels rotated and balanced. However, the problem persisted. So, to date I have had the car Aligned three times and had the tires RoadForce tested (Continentals). Two failed this test and are now on the rear.
So, here is the description of the issue. The Front Drivers wheel feels like it is "bouncing/Vibrating". This is the side that had the bad Strut and the primary side that the Stealership worked on. I have an appointment to take it back in on the 16th but the problem is getting progressively worse daily. If I didn't know that the Struts and Springs were brand new, I would say I needed new Struts! It is a very strange feeling as it's not a true vibration like an unbalanced tire or worn bushings, it's more of a "loose" up/down movement that I feel in the floor and the steering wheel but it is definitely coming from the Drivers front wheel. Yes, I have put the car on jacks and made sure every bolt and nut are tight. Could it be a wheel bearing?? Just thinking through this more as I type. :dunno: This issue is not speed specific, while it does increase and is more noticeable at highway speeds, I feel it at 20 mph as well.
I have spent some money on this car since I bought it last year and I plan on keeping it for at least another two years. At this point I don't care what the problem is, I just want someone to figure it out for me as I have exhausted my limited knowledge.
Any suggestions would be greatly appreciated.
Are there any E46 Forum people in the Columbus Ohio area?
