Control Arms both sides
Lower control arms both sides
Tie rod ends both sides
Wheels balanced by a proper machine
Brand new tyres on front
Wheels checked for buckles or cracks

Any help much appreciated

Steering shaft U-joints? Is there a rubber bushing in the steering shaft somewhere? I also have a wobble at 60-80mph while cold. Goes away almost completely once I've been driving for a bit. You've done pretty much everything.

What X5 are we talking about here? You done the upper strut mounts?

I’ve got a bmw e53 3.0d not sure but Ive had the steering rack done
Upper strut mounts?? Thanks for a reply

Do the 3.0d's have 4 corner air? If not, the upper strut mount is part #1 in the diagram at the link. But there are other dampers in the assembly as well. No idea if any of them might be responsible for a shimmy though.

Are your wheels standard? You mentioned putting later model X5 wheels on. Did you use (do you use) hub-centric rings? If not, then you can get shimmy at high speed, as the wheels are not centred no the hub correctly without hub-centric rings.

These...

Not put different wheels on it they are original ones from new

What front control arms did you use and did you preload them properly when you installed them?

Hi overboost
No the control arms some one else did about 5 months ago they were quite cheap ones also! But would hat cause this wobble? I thought when they went wrong they pulled left and right?
Thanks for helping

I would guess these are your problem. I would recommend Genuine BMW but there are Lemforder and Meyle for less. Make sure you have the X5 sitting at ride height when you tighten the mounting bolts. Tightening them in the air will cause the bushings to twist when lowered, causing premature wear.

Or you can go Poly on the bushings. Lifetime warranty from Powerflex. :thumbup:
