SmackJackTheCrackerMan 54 Report post Posted October 29, 2020 Since I picked up the car last week I’ve had a good ol’ steering wheel wobble. I assumed it was that the new tires had not been balanced properly, but I’ve had all 4 wheel & tires balanced again today (only slightly off) This has helped some what but anything over 80kh it’s still there. what would be then next port of call? wheel bearings? What is the best way to check? Quote Share this post Link to post Share on other sites
aja540i 1906 Report post Posted October 29, 2020 Are the rims nice and round? They can be balanced and out of round if they have smacked a pothole etc, some tyre places will look for it but some don't... Quote Share this post Link to post Share on other sites

qube 3570 Report post Posted October 29, 2020 my money is on thrust arm bushes, if its doing it at 80kmh while cruising and not related to braking (in which case it would be warped rotors or similar) Quote Share this post Link to post Share on other sites
NZ00Z3 187 Report post Posted October 29, 2020 Fit front wheels to back and back wheels to front and see if it changes. If it does then its something to do with the wheels. Quote Share this post Link to post Share on other sites

If it does then its something to do with the wheels. Might be an issue as the rear wheel are so much wider than the fronts. Quote Share this post Link to post Share on other sites

See if anything is loose that shouldn't be. Quote Share this post Link to post Share on other sites

Alot of force transfers through them, you wont feel it by hand, I didnt notice using a mid size pry bar but changed them anyway. Quote Share this post Link to post Share on other sites

Think I’ll give this a go. is this what I should be replacing? https://www.fcpeuro.com/products/bmw-suspension-control-arm-bushing-33326775552 I’ve also ordered some hub centric rings as apparently the wheels are designed for a 5 series so has a slightly larger centre bore.

Eagle 1662 Report post Posted October 31, 2020 (edited) Front bushings. You may be off replacing the whole arm long term though. If the ball joint fails on your new bushings then you are going to be buying a whole new arm. https://www.fcpeuro.com/products/bmw-control-arm-bushing-kit-e81-e90-e65-e66-meyle-31120304308my https://www.fcpeuro.com/products/bmw-control-arm-assembly-front-left-front-31126769797my https://www.fcpeuro.com/products/bmw-control-arm-front-right-front-e88-e89-e90-e91-31126769798my If you running without required hub rings then thats likely your issue Edited October 31, 2020 by Eagle wrong car Quote Share this post Link to post Share on other sites

I got the hub rings today 74x72.6 and it’s like a different car. No more wobble at all. Thanks. Quote Share this post Link to post Share on other sites
