I want to add my $0.03 here. First off, Jack has been playing this game for a long time and knows it well. I take what he says seriously.
I am a pretty serious wrencher myself. I have a lift in my shop, and a respectable collection of tools. If I can't do it in my shop I have friends with even bigger shops and bigger tools.
So, with that in mind I sat through the videos on Gregg's site that show the singling of the rear end. This is not for the faint of heart. The shop it was done in had fat air hoses, heavy duty pneumatic tools, and STILL had to get the "gas axe" (large acetylene cutting torch) out for a lot of the fasteners involved. The truck's rear end is heavy, you need a SERIOUS scissor jack. The axles are heavy, they use a forklift to pick them up. They have a grease pit to get under the thing. The ETSr hitch weighs 750 pounds.....And so on, and so forth. With all these heavy duty tools two guys are spending quite a few hours doing the job.
Can it be done in the driveway? Yes. I have a 25 horse tractor that will pick up 750 pounds. Or, an engine hoist can be bought/rented. Harbor Freight is 20 minutes away...If you're a decent fabricator and have a good welder (I do) you can build the bed....... but it is a serious project.
If you are considering this, I would highly recommend watching these videos.....
