Before I start, I want to say that I was/am a total noob to the lift scene. I got my hands on a little extra money, got impatient to get my truck lifted ASAP and didn't do nearly enough research. Don't be like me.
I just had a decent kit installed. Toytec/Eibach coils, 5100's all around, a 2" AAL and a diff drop. The goal was a level 3" lift. When it came time to drop my truck off at the shop, the owner asked me what height I wanted the front 5100's set at. I said that I had no idea, but that I was looking for a level 3" lift. He said "well then I'd go with setting them at 2.5". Being a trusting and ignorant asshole that I am, I said go for it. I got a 4.1" lift, 0 caster and vibrations like you wouldn't believe.
I installed a carrier bearing drop kit to see if that would help with the vibrations (it didnt). I backordered a set of TC UCA's to get some positive caster. I then went back and spent a week reading everything on these forums and spoke with the guys at ToyTec. Apparently I should have had the shocks set at 0 or 0.85 at the most - anything above that and a blown axle or shock is a sure thing. My truck is hanging out in the driveway until it goes back to the shop on Friday.
Help me out:
To get rid of the vibrations, should I set the shocks at 0 in front, giving me 1.6" lift with the springs and leave the 2" AAL in the rear? How bad will that rake angle look?
If I stick with the 1.6" lift, should I pull the AAL?
Should I set the front shocks at 0.85" for 2.45" front, 2" rear and try to deal with vibrations by way of the carrier bearing drop/shims?
Should I cancel the UCA order while I still can?
