Re: Big Red, my 68 3/4 ton GMC

Well I started the disassembly of the rear today. I got most of it done and took pictures along the way. I started by jacking up the rear and put some jackstands under the frame. this got the tires just off the ground to take the tension off the leaves. I decided to start in on the spring hangers first. So I center punched all the rivets, then worked my way from a 1/8" bit to a 1/2" bit and drilled just deep enough to pop the head of the rivet. Heres what it looked like in phases:













This was the first hanger, so then I just had to do the other 3! So after I got all the others drilled I disconnected the brake line, e-brake cables and shocks.
Next I took the u-bolts off and got the springs out of the way, here's how it looked:





Then I had to lift the frame high enough to roll the axle out from under the truck. To do this I jacked under the carrier bearing crossmember, and rolled it out.





This is as far as I got today. If the weather cooperates tomorrow I plan on pulling the bumper off (Its welded to the frame in about 10-12 places so I get to grind it off) and start removing rust/undercoating so I can start painting and reassembling.
