My 2003 Montero Sport has a positive camber alignment problem. The outer treads on my tires are wearing out and just today had all 4 tires changed. Purchasing the 4 tires came with a free oil change and 50% discount on wheel alignment. As soon as the work was done on my Montero Sport, I noticed that the alignment was still the same and asked the mechanic why is that? He replied saying that my car didn't have a camber adjustment and the only way to fix the positive camber alignment was to have the "shocks" changed. Is that TRUE?
