Wow, and I was mad about ny stuff.
Brett,
Needs some details about what you need help with. Also, you might try listing a single question to a subject. Some people may have an answer to part of the question, but hold back if they are overwhelmed.
Springs, did they collapse? See my post about that in this section.
Alignment, A lot of this is tied to the springs. Also may have to do with other parts having problems. Details though, does it pull, is the camber way out, Not enough caster?
Spring Perches. This has me concerned. Sounds like the stud was loose that holds the spring perch to the I-beam. Hopefully your weld solved that. But seperating the drive shaft? Your getting some travel in your front end. Not a bad thing if somewhat controlled. You may need a custome driveshaft now. My 5.5" lift kit has not giving me any problems with the drive shafts. I'm still leaving the swaybars hooked up though. And the shocks limit my travel to a safe distance. You need to check that stuff. RTI ramp time to see what is binding and what is traveling to far.
Brake Lines. I got new extended ones when I did my lift.
This sounds like the classic case of everything sucks till you get it right. Once you fix all these things you'll love your set-up.
Good Luck
