Hi all, our 2011 Lexus IS250 has recently developed a wobbly wheel, particularly noticeable (visually) at 40mph+. Only on the offside rear, NS is fine.

It does have 20mm hubcentric spacers on the rears but I have removed them and re-tightened them along with the wheel lugs and they seem fine. I have also tried to shake the wheel while on stands to see if it was a faulty wheel bearing but seems tight with no vertical or lateral movement.

I have taken the car two indy garages now and they have no clue. One garage noticed the entire rear hub was fairly new (1-2 yrs) after a possible minor crash by previous owner(no paperwork unfortunately). I've been under the car and the subframe looks straight though.

Amy ideas anyone? I'm stumped. I suspected it might be suspension related rather than brakes or wheel now? My next step was to take it to a wheel alignment place and see whether it could be worn bushings or similar.

Yes, swapping the wheel still has same problem on OS rear. Other side is fine, so ruling out wheel and tyre. confused

Have you tried swapping wheels around to see if the wobble moves?

Wobble can be seen from behind following in another car and also driving side-by-side.

Not a huge amount of wobble to be honest and driving the car, I can't feel anything different.

The tyre is only a few months old. I couldn't feel any noticeable bumps on the tyre itself.

I did torque the spacer bolts and wheel lugs the other day and they were looser than they should have been, can they work themselves loose?

The missus proclaims innocence regarding kerbing...

I have a spare set of wheel nuts waiting to go on as soon as the wheels are repainted. I'll try putting this new set on and see if it makes any difference. Thanks

Torque everything up and double check, maybe jack the rear of the car up (remember safety first etc) and spin the rear wheels up, look from the underneath to see if there's anything obvious causing it.

Last time I had rear wheel wobble on one side was a very slightly bent hub, caused by ttting a kerb, however it did muller the wheel in the process. If you car has wheel studs then not sure, but would a slightly bent stud cause this kind of issue perhaps?.

Hmmm having some further online research, it could be wheel spacer related. I've run spacers on nearly all my cars and never had any issues so ruled it out.

I'll try swapping the spacers round and see if it helps.

Update here: https://www.pistonheads.com/gassing/topic.asp?h=0&...

TLDR: The cheap spacers I bought sheared their lugs off!

Thanks Samoht, I'll certainly remember it for next time! And to think I questioned Lexus' unquestionable reliability!
