Wobbly E30

[SIKE30 0]

Hi guys i have a 1986 318i and when i used to drive it on ruff roads it almost felt like the wheels would fall if it just felt real loose. So i changed the the lower inner and outer balljoints the caster bushings and i checked the swaybar links and bushes they arnt to bad. And now when I drive it on the motorway it has a wobble almost as if the wheels were loose. its been wheel balanced n and aligned new tyres n tha mags arnt bent. Can anyone help me plzz.

warped brake rotors? sounds like you've covered all the usual suspects. Is it at any speed or over a certain speed range?

If the mags are not hubcentric, that can cause this problem. Measure the hub and compare it with the mag. You might need hubcentric spacers.

Steering Rack itself?

When i got the mags i went and bought a set of hub adpaters for them so it shudnt be that. The wobble starts to happen on the motoway at about 110kmph and then it continues after that at lower speeds aswell. And i also changed the steering rack ends a month ago forgot to mention.

any vibration? doubt it but could be a wheel bearing.

the brake rotors were machined all around about a year ago when I did the pads. I got told that the loose feeling could be caused by the front strut mounts. has anyone had that problem?

Define "hub adaptors" hubcentric spacers or adaptors ???

yeah there is a viabration when it starts to wobble But it doesnt make any noise or anything. And passed its warrent afew months ago. hmmm but ill chek the wheel bearings

hubcentric spacers i think. They are plastic rings that slide into the centre of the mag and fit snug on the hub of the vehicle.

[*Glenn* 854]

Have you got spacers on the hubs ??? or just hubcentric rings to locate the wheel on the hub ???

I have spacers on the front.

[*Glenn* 854]

I have spacers on the front.

Thats what your problem will be then. They wont be matched to to the hub & mag. The inside of the spacer must fit the hub correctly and the outside must align the mag correctly. You'll probably find the sizes are different. Your tyre guy should know this.

could be a number of things. wheel bearings, steering column. I think Glenns got it spot on with your rims not being hubcentric.

Doesnt help much with a completely knackered L/H rear tyre. Fairly new too. At least hes on the right track now, new tyre should sort it.

Thanks again Glenn I changed back to the factory rims and tyres and the viabration is completely gone. Its amazing how bad that tyre was considering it was only 8mths old. Thanks again.
