on my 1993 ram 250 with the cummins turbo diesel and 1 ton front axle, i am having a odd problem with the camber angle..in the drive way looking at the truck the camber angle is way off (negative camber) and then i put it in the garage and back it out again and all of a sudden the tires are straight again....and it does this on and off one day it can be out real bad then the next it is completely straight....to fix this do i take the 4 bolts off the top of the axle end where the pivot bolt is and tighten that while it's in the straight postion or what do i do?

Sounds like you need some ball joints and or tie rod ends.

Is it a 2wd or 4wd? Either way it sounds serious. I would check it out soon.

king pins are worn out.

Its your King Pins for sure. I had the same problem. Find a good 4x4 shop, or suspension shop.
