Wheel alignment help

[h2tbilisi]

I've got a problem with the alignment on the front of the truck.

It was bought nearly new with a 4" lift already installed and it looks like the wheel alignment wasn't checked after installation.

The truck doesn't pull either way when driving, but I can see that the camber front wheels is way out. The tires are wearing excessively on the outside and I can actually notice by looking how bad it is (the wheels have a + camber so bad that you can see by just looking at it).

Unfortunately, Hummer or GM dealers aren't all that common in the mountains of the Caucasus (the nearest one is in Turkey, approx 500 miles away).

Does anyone know how I can do it myself? (I've got a reasonable technical background, so just need to know where to adjust).

Any photos would be great.
