Default Help Tracking Down a Front End Vibration

I don't usually post on the forums anymore because everything has been so smooth with since owning my M3, but for the last 1,000 miles I've had a front end vibration that starts at 80 mph and continues as speed goes up - and in the last 250 miles shaking (or almost like a shimmy) has started as low as 45 mph.

What I've checked/replaced: Stoptech rotors and pistons rebuilt last week, GC sway bar (installed, greased, correct preset), shaking does not change if pressing on brakes, new steering rubber guibo (had about 1" play in steering and this fixed it), switched out BBS's for someone else's good wheels to see if it was a tire/wheel isssue, and brand new FCAB's 500 miles ago when bearings were done.

On Tuesday I'm taking it to an alignment shop to see if it's even possible an alignment could cause shaking even though it's almost impossible. So I'm almost out of ideas at this point. I'm not sure if it's possibly something in the steering column that could be lose. When I apply downward pressure on the steering wheel with shaking, the shimmy can almost be controlled - and the same vibration that I get through the pedals also calms down.

The only other two things I have noticed is a slight pull to the drivers side under breaking and when I air out, I notice a slight difference in camber as the passenger wheel is more tucked than the driver's. Other than that nothing else. If anyone has any ideas I'd much appreciate it as I'm pretty stumped.

You said that you replaced front wheel bearings?

Only thing in front to check would be inner and outer ball joints and tie rod ends. Have you checked anything in rear? Lots of possibilities there. From axle U joints, bearings and ball joints.
Seeing as you are in Las Vegas, do you know where I can get an AC recharge here? We drove down and it was cold when we left and today found the AC needs recharge. Drove from Salt Lake City with no air.

A vibration making itself known at speed could be attributed to an unbalanced wheel/bent wheel. Find a shop that as a Hunter wheel balance machine that can detect this bent wheel matter.

Yes go to Southwest Bimmers if you are here Monday. Ask for Shane if you go. He will take care of you. Tell him Tony sent you. I'll get ball joints and tie rods checked Tuesday but nothing should be worn. I had everything inspected when the rods were done.

I switched out wheels. Not a wheel/balance issue.

Default Re: Help Tracking Down a Front End Vibration

Thanks for the shop info. I will call Shane on Monday. I'm here all week.

I thought you had talked about replacing bearings as wheel bearings. Since you haven't that would be my number one suggestion. As someone else asked. Not really that expensive and they probably have lots of miles on them anyway.
Rough bearing could certainly give you the symptoms you have. Does anyone ever repack front wheel bearings? Used to be something a person did on a regular maint program! I guess those days are gone now everything is sealed.

Tony
Big thanks for the tip to SW Bimmers. I went over today. I did mention your name and they had good things to say about you.
I felt like family there even though I had never been there before. Even some customer's little dog jumped up on the couch and laid down beside me like he knew me.
Very happy but hope I don't have to visit again! No one likes to have to have work done while on holidays!
Once more I do have to say that this forum really does help each other. I had recently posted a thread about how well this forum works.

Default Re: Help Tracking Down a Front End Vibration

I appreciate all the help, however I believe the issue is the rack itself. I have definitly beaten on the rack since owning the car sliding it thru turns, so it's a fair guess at this point. There is no play and bearings are actually in great shape - they spin freely and smoothly. There is no vibrating anywhere on the car except thru the rack. The car has literally every wear component that could be replaced, replaced in the last year - front and rear.

I ordered a rebuilt Z3 rack for $200 and am going to switch it in by next week hopefully if the part arrives on schedule. I will keep this thread updated to help with anyone else who might be experiencing the same issues as me.

I couldn't feel any play in bearings and they spun easily but when I removed it was clear one was bad. Once they wee replaced all my issues were gone.
