Ok I'm putting in a 4.5 lift. I did post on the lift thread and got one response but need more info. I have the coil and lower attached (not tight yet ) on driver side but I am having trouble with the upper. I put my full size bronco bumper to bumper with jeep and used a 1 3/4 ton comalong to try and get bolt in place it's close but no cigar. I guess what I'm asking would it be easier to put lower and coil on pass side with both uppers unhooked then try to put uppers in place? I think the pass side is fighting the axle from turning to get the uppers hooked up

 

I just did the rough country 4.5" and the instructions said to put the uppers on first then the spring then the lowers

 

Install control arms first, Upper and lower.
If you have stock steering, remove drag-link from passenger knuckle.(the 2 hammer trick works good)
Also may need to unbolt one end of track-bar.
Then lower the axle.
It should easily droop far enough to install springs
