I can't speak for psfred, but I'm sure about it. In extreme camber cases, tire wear issues can be the result, but usually because of the effect that the incorrect camber has on the toe setting.

Wouldn't excessive toe-in cause tire wear on the outside edge?

Yes you are correct, Good catch. Toe in wears outside, toe out wears inside. The point is that the TOE can be effected by camber, but it is the TOE being set incorrectly that will be responsible for the vast majority of such tire wear.

Camber was good.

Caster was good

Left toe was .02, right toe was .08, spec is .13 to .29.

My idler arm was "just slightly" loose they said. So I'll get the kit and put that in there some weekend morning.

Forget the left toe, right toe bit. The toe should be set to zero as measured between front and rear of the front wheels. I don't know where the .13/.29 business came from. If you set your toe to .29 either in or out, your front tires will be ready for the scrap heap in 10,000 miles.

From experience, cupping is normally caused by worn shock absorbers. They have probably been bad for some time as cupping does not happen overnight.

The wear may be caused by the bad shocks, too, but sounds like an alignment is inorder .

However, I probably would not get an alignment until I replace the shocks - if they are bad. A good alignment mechanic will tell you which parts of your suspension is bad and will not align your car until those are fixed .

When checking for bad shocks, I push down hard on the fender area above each tire and watch the car bounce back. If it bounce up and down, I have found the shocks to be bad. If it comes back up slowly and not bounce up and down, I have found the shocks are good.

I'm just reading from the printout. Every vehicle I've ever done looks similar to me.

The bounce test does not seem applicable to these cars. My old shock had spewed all it's oil, yet the car still passed the bounce test.
