Heres my list of thigns to check.
Hub Bearing
Ball Joints
Water or fluid in the tyre
Un balance rim
Bent rim
Damages tyre
Steering rack is fooked
Torsion rubber is foorked or missing
Get a wheel alignment and get em to brake the tyres off the rims and see if anything is inside and ask em to balance the tyre to the rim

Thanks Tweak,

but

has been done

Umm do the centre bore's of the wheel fit snuggly over the hub?
Is the wheel relying on the studs for correct location?
If you take the wheel nuts off but leave the wheel fitted over the studs can you lift the wheel up/down or left/right on the studs?
If so then that's where your problem lies.

That has already been covered a couple of times.

None of my wheels are hubcentric, though i have tapered nuts and always make sure i take the greatest of care when removing and replacing my wheels to make sure there is no balance issues.

Well, if i took the wheel nuts off the wheel comes off, but if your asking , do the studs move in behind the rotor, no they dont, there is no play (but i think tihs is an issue the fact they dont move )

No

Ok this is the last time I will suggest it. Check your steering rack bushes they may look ok from the outside and be stuffed inside.

No. Jack up the car. Loosen the nuts and let the wheel hang from the studs.Then put your hands under the wheel and lift it upwards towards the guard.Feel that clunk? That's you issue. Dont rely on the fact that just because none of your wheels are hubcentric that its not the cause. I've fitted well over 500 sets of aftermarket rims to cars.Some have no issues not being hubcentric. Others are a complete nightmare with being centralised. From your description and what you have already checked & investigated there is little else it could be.
Some wheels have the PCD holes drilled to suit up to 14mm studs. So when you have 12mm stud you get at least 2 mm of possible runout.

Bent studs?

Except that the nuts are conical, and thus reduce that runout to almost nothing, and even less when the nuts are done up correctly.

Just coz a wheel has a conical seat and a nut is conical means the wheel doesn'y have to centralised hey? Thats the most dumbfuck thing i've heard.
Good luck fixing your problem.

**CrUZida** · 31-03-2009, 05:55 PM

How can things that are (supposed to be) the same angle not centralise when done properly?

**LeeRoy** · 31-03-2009, 08:29 PM

Unless the hub locators are a 100% fit - which would require a press to get them on/off, then they are only ever going to be centered by the wheel nuts. The hub locator is only ever as close as the nuts anyways so your in the same boat regardless of what path you travel down.

Cruzida, even if theyre not the same angle, as long as the nuts are conical it will center the wheel - even if the wheel requires shouldered nuts.

**auto351** · 31-03-2009, 11:12 PM

you could jack up the car so the wheel is just off the ground, then rotate the wheel by hand and see if its the gap between the tyre & the ground increases or decreases.
