Front install:
My front setup includes OME 881 heavy duty coil springs, Cornfed 2" aluminum spacers, and Bilstein heavy duty shocks.
First thing you should do is spray all the bolts with some PB blaster. This stuff works wonders on stuck and rusted bolts. Just spray it and let it sit for a few minutes. Makes life easier.
Then raise the vehicle up and support it on jack stands. Make sure to lift it high enough that you can droop the lower a-arm assembly down far enough that it doesn't hit the ground. Then remove the wheels.
