Just lowered my truck 1/2 drop.
now i think pinion angle is off kinda clunks in drive at start and whole rear like moves.
how do you correct it will i need to tear rearend apart?

 

My lightning was lowered 2/4 if I remember correctly and I don't remember having to adjust the pinion angle but it can be accomplished with a pinion shim kit, just Google it and you will come up with a variety of companies that sell them.
