the steering shaft is another concern, but should telescope out enuff, but sometimes can be hard to move. i had a buddy put a body lift on and the shop where he bought it told him it would pull out enuff to work, but it didn't and it messed his rag joint up...come to find out it has some sort of plastic holding the shaft together that usually shears and lets the shaft pull out a little, and his didn't shear, i think you can see 1 or 2 little plastic "tits" on the shaft and iirc he had to drill them out the thickness of the female part of the shaft to get it to telescope.....and replace his rag joint.
i've heard people use a torch and melt these also, so shaft will telescope, in my experience they have always telescoped fine, i guess it sheared the plastic, i didn't have to drill or heat, i've only installed 3 body lifts tho, so there is a possibility it maynot want to slide out, so keep an eye on your rag joint and the shaft where they slide together b4 something breaks....if any1 knows more about this please shed some light
