I've removed the bodies on range rovers a couple of times (only refitted once though).
The first time lifting off I opened the doors and fed through a couple of slings and lifted it off with a telehandler, which was fairly easy, but the aluminium roof panel suffered, though the steel frame was fine. I found a high lift was ideal for initially separating the body from chassis each side separately before lifting the body off as a corrosion bond had formed between the bolts and chassis. You need to thoroughly go round the entire vehicle first as there are a lot of connections between body and chassis/transmission including items like a rubber gaiter between transfer box and body which I didn't know about until afterwards :oops:
The second time I was trying to preserve the body, so instead of hoisting, I raised the body at 4 points under the front of the sills and under the rear cross member, high enough to roll the chassis out. I had to raise the front quite a lot and slide a scaffold board underneath the sills so that the front supports (builders’ trestles) could be moved out wider than the rear wheels.
Refitting was the reverse of the raising the second time. The chassis was rolled back into place under the body and the supports slowly lowered a bit at a time to bring the body down square onto the chassis.
Like repairing sills with Box section, it is a steady job and not one I fancy doing again without some proper over head hoists. I suppose a good scaffold frame and some tirfor winches would work well.
No idea what they weight. Enough that you wouldn't want to drop one on your self so take care.
