trying to correct pinion angle in the frt will screw your alignment and your truck will handle like shit the proper way to correct pinion angle in the front is to cut and turn the pumpkin or the knuckles on the diff.

you can keep steering geometry by putting in a couple superflex u joints,they give an extra 10 degrees,my dads chev had the same problem,thats cleared it up just make sureyou buy a spare cause they dont sell them in canada yet. shims suck cut and roll is the other way is the other way,not as simple as changing a couple u joints yo
