17 rcsb 2/4 drop vibration

They went in like instructions said to. If i turn them around it would make my pinion angle worse. The pinion was level on the app but the truck was on an incline so it should be pointing down if i were to park on a flat surface.

Yeah i understand that but what im saying is if i put in a thicker shim there is going to be a point where the pinion points up and thats what i wanted to avoid. Called and verified shim orientation and they are in correct.

there is a lot of information about driveshaft angles, just need to measure and do simple math, it really isnt hard http://spicerparts.com/anglemaster/measuring-angles

Was the rear lowering kit a flip kit? If so I think the shims are backwards. However my kit is the belltech 5.5 its a rear flip and the shims went thin side towards the cab and it got rid of 90% of the vibration.
