Burnt RR tires in 600mi (rear camber / wheel issue)

[cwatt]

Hi all,

I've just cooked the insides of my tired in two weeks. I drive about 100km (60mi) a day, which means about 1000kms (600mi). What I do know is that there is excessive travel in the rear left shock mount. I fiddled with it (was making a knocking noise), but today the noise the noise came back.

I've taken a photo of my tires, and the camber is absolutely ridiculous. It was bad enough already, but if I make it through the week without blowing the tire, I'll be surprised.


IE Camber Kit? Anything else that might cause this? It honestly looks as though the left side is about an inch further outboard... ????

*NOTE*

I had my tires recently switched sides... about two weeks ago. So be forewarned when trying to look at tire wear as any indication.

Camber doesn't eat tires, Toe does.

How old are your trailing arm bushings? Subframe bushings?

You can measure camber with a 2 foot level and a ruler. Just get it vertical and measure the distance to the top and then google for a triangle calculator to do the math.

That said, your extremely crooked shots don't look like you have that much camber. I'd bet on a shit ton of toe. You can pull a quick measurement with two flat boards and two tape measures, or you could buy a pair of toe plates.

My first suspicion would be bad trailing arm bushings. If replacing those doesn't fix the asymmetrical camber, the trailing arm or subframe is bent.

Hey all,

Thanks for all the great input. I work and go to school, so my apologies for the slow response.

I think my subframe bushings might be on the out. There is a knocking sound when slowing down from reversing. I first thought it was my battery moving around, but from reading around on the forum it sounds as though it might be the bushings.

I'll see if I can measure the toe when I get home. Is toe adjustable? Possible to do it from home, or best to have a shop do it?

I think the trailing arm bushings are good. Then again, I cannot confirm nor deny. Any 'tell tale symptoms' other than worn tires?

In the stock configuration there are no adjustments for the rear wheel alignment. Worn or bent parts will be responsible for any rear alignment issues.
