stumped on 50-60mph shimmy

[MO525]

It's more of a mild 'clink' than a 'clunk' really. It might be the collar nut, I haven't checked that one yet... could it also be a ball joint, or the steering box moutning bolts?

Cheap/easy fix.
You really ought to see how all that spindle/strut/Thrust Arm/lower control arm pivots when you turn it!
Talk about bizarre!
I installed tie rods yesterday and observed it with the tie rod off.

That Sway Bar end link takes a HUGE twist when the wheel is turned.....
Clink? You bet!
I replaced my end links weeks ago.
EASY....as long as the nuts come loose without a fuss.

Ok thanks! Will be bringing into the shop that did the front end a month ago...it's still under warranty, and if any of the parts they changed are broken, or they installed it wrong... they should replace it all for free.

In any case, I'm gonna bring it to another indy shop that specializes in European suspensions... just for a 2nd opinion... I won't tell 'em what I had done, or what the problem is first... I wanna see what they have to say.

It's just a mild shimmy..no where near as bad as it was before. It doesn't shimmy anymore under any kind of braking. Only from 50-60mph. Will see. I'm also sourcing some hubcentric rings just in case.

I just got back from my BMW stealer today after a botched alignment. It was a few degrees out of align - it still didn't correct my shimmy. Like most others, it comes on a 50 and disappears at 60. I've been hunting my shimmy for over a year now. Here's what I've replaced:

Thrust arms
Lower control arms - Replaced my aluminum ones w/ steel - No difference!
Sway bar end links
Tie rods
Shocks - Front/Rear
Rotors/pads
Brand new tires
Hunter GSP9700 balance
I'm using hubcentric rings on 17" M5 replicas (not bent!)

After replacing all of this.... I still have my damn shimmy!!!

Well after talking w/ BMW techs today, they recommended I change out my center support bearing and driveshaft. They'll do it for $1323!! I'll probably get a guibo and center bearing ordered today from Patrick... BTW my car has 125,000 miles so I figure it's ready for it anyway. Hopefully this will correct it!!

Thanks for all the help guys!!
