Steering wheel wobble

Recommended Posts

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?

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...

After market wheels that are missing hubcentric rings?

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)

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.

Might be an issue as the rear wheel are so much wider than the fronts.

I suppose it's a case of jacking the car up and giving everything a good shake! See if anything is loose that shouldn't be.

This, ive had 4 euros with 80-100kmh steering wheel shake and its been thrust bushes / lower control arm every time usually around 100-120,000km on the bushes.

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.

Thanks Andrew! Think I’ll give this a go. 
is this what I should be replacing?

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.

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.

Correct. I got the hub rings today 74x72.6 and it’s like a different car. No more wobble at all. Thanks.
