Re: doors sag,play in hinges
Your '93 would be an IFS truck so it goes on the other half of the GM Forums. However...[img]images/graemlins/grin.gif[/img]...I've done hinge pins and bushings on a '76 K1500, '83 K2500, '86 C2500, & recently a '94 Suburban. Do you happen to have access to a shop hoist or one of those rolling little cherry picker-like cranes? IF you do, GREAT, my dad and just pioneered an easy way to to do this task. What we did on the Suburban (which will probable be closest to your truck) was roll the window down, wrap a towel around the upper part of the door and gently lift it with the crane. Just enough that it takes the slack out of the saggin door. This is all done with the door open to it's fullest. After you take the side load off the hinges you can pop the keepers off the pins and drive the pins out with a punch. PAY ATTENTION to which direction the pins go as well as the bushings. Our hinge pins and bushings kit came with new keepers but the OEM ones were more robust, so we reused them. Now with the pins out you can roll the door (assuming it's on the crane) away from the rig.
(If you've got power windows/power door locks, post again, I'll tell you how to get some slack out of the wires.)
Okay, now you can pop the bushings out and take a iwre brush of ssomething to the hinge surfaces and clean them up if you want. Ours had a few years of WD-40 and dirt build-up on them. After that you just pretty much reverse the process. Tap the new bushings in with a hammer, top and bottom, bring the door up close and start the pins. After you've got the pins lined up, don't be afraid to whack those, you'll need to. Install the keepers, almost done.
The door spring on our Suburban is a coil spring, if your's is, I'm sorry. That thing is a PITA to get back in place. It takes a cople medium sized prybars and some coaxing. It is an incredibly stiff spring for a door, but those doors are pretty heavy.
If you don't have access to the crane I mentioned, a floor jack placed under the door with a 2x4 and towel will acheive the same thing. You will need a second person though to hold the door upright.
Did I leave anything out?
