How do you adjust camber on a 1988 Chevy truck?

Answer 1

EIther there is no adjustment. It is built into the drive axial. Use shims, or body pull.

OR,

Some have an eccentric round nut adjustment up on top (of the steering knukle) where the top ball joint would go as in the 1986 model 4 wheel drive. Needs a special tool and usually is rusted on good. Best to take to a shop that can deal with those odd balls. Very expensive.

I had one of those trucks. No way visible to see how to adjust Camber and it wears out your front tires real fast.

Or,

Third option cheap do it yourself. Google for Camber Kit (Silverado) buy from Einbrach something name like that special offset ball joint to - +2 degree camber to replace old ones if not able to shim /bend front "axial" or adjustment eccentric cam is frozen on too hard to knuckle (do not heat those since it will take out the temper and ruin them) press out old top ball joint and replace with special offset aftermarket kit to get the wheel in alignment. Cheap way to go for do it yourself.

Silverado is great for that year 350 CID with 700R4 tranny runs great; only the front ball joint camber adjustment on the 4 wheel drive is a joke.
