Looking to get some info on the process of properly adjusting the eccentric cam bolts, located on the lower control arms (at the axle end).

When driving my truck, after the 4.5" Fabtech lift kit was installed, it feels like the front driveshaft is 'grinding' (possibly too little or too much angle???).

Does anyone have a FSM that they can scan or list out the process of adjustment the cam bolts, to properly set the pinion angle?

Any and all info concerning the eccentric cam bolts and front pinion angle is appreciated!

Get a angle degree thing i forgot what their called lol put it on the drive shaft and i would use the upper control arm to so it pushes the axle forward alittle more which might help but you prob have control arms right? If you do the bottom bolt its gonna pull back more towards the fender which you don't want.

I am pretty sure sthe upper control arm does not have any adjustment features, just the lower control arm at the axle end..........

upper control arms control pinion angle, they stop the axle from rotating under load
