Smile Hi, Sure its been asked before :)

Hi

Im sure this ones been asked before, but....

I have a 1.9 early Z3 cab, and its getting through rear tyres especially on one side at an alarming rate (i dont drive like a girl racer... much) its also developed a bit of a humming when driving, one of the rear wheels (on the opposite side to the badley worn tyre) feels a bit like a bearing may be a bit worn?
Im guessing the tyre wear is something to do with the camber/toe in, but not having had this type of car before im not sure where to start looking, im quite used to working on my own motors, but was just after a few pointers of what to check out first.

Thanks

Claire

Just to follow up, reading through other posts, sounds like there is no adjustment in the back, so i guess that leads me to thing something is bent/broken to push it so far out?

There is no adjustment that comes stock from the factory. There are after market toe and camber kits available. Any car that has been lowered with shorter springs or coil overs will have an increase in negative camber. The only way to fix it is to add the aftermarket toe kit. Most leave it be as the increase in tire wear is usually not to bad. A car with a bent rear suspension will have the toe out of spec. Either replace the rear suspension or if it is not bad, the toe kit might get you back within spec. Either way, the first thing to do is pay $80 and get a 4 wheel alignment so you know what direction to go and what to look for unless you can see bent parts.

Only on one side? Check springs. Humming could be a bearing - yes. If a spring is not broken I would take it to someone to look on the rear suspension as a whole as Wertles above recommends.

How are the tires looking, I had a simaler thing and the tire was actually cupped a bit, you couldnt see it without a pretty careful look, if one is wearing the other may have some issues as well.

I have the same issue right before i put the car in storage this winter. I talked with my mechanic and thniks the springs are borken, some I have to take care of before I put a new set tires on.
