    You can do it yourself. The biggest things you have to worry about are having the right tools. And having the time to do it since its going to be outside. You may run into some snags here and there that may sit you back on the time. As you are installing it, you will find that getting all the old rusted stuff off will be the hardest part. And if you are doing it yourself, you may want to have a extra jack and maybe 2 sets of jack stands. I personally wouldn't waste your time trying to take the u-bolts off the traditional way. AS you are going to be replacing them anyway. Cut them off, just be sure you dont cut into the axle tubes. Also make sure you jack it up a little higher than you would think. Cause your new springs will stick down further than your currents. Or after you get the new springs installed you will have to jack it up to get the new tires on. The only other thing I can think of this early in the morning is to wait till you get the weight of the truck sitting on the new springs before you tighten everything down to specs. This will help get everything lined up and seated correctly. This will also recommended to cut down on additional driveline vibrations. You may still get some but thats part of the gamble with installing a new lift. You may need to lower the T-case after its all said and done. Just use those spacers provided by GM. They should be there, less someone else has removed them. They should be right there above the nuts at the crossmember. You just jack up the T-case to take the weight off them remove the bolt, slide the spacer in between the crossmember and the frame and then bolt it back up.

    I think ftn96 covered it pretty well. Definately don't pay someone else to do it. a straight axle lift is the easiest lift to do. tall jackstands or some big blocks of wood and regular jackstands will work, along with a floor jack. If you don't have the means of cutting the old bolts off start spraying them with liquid wrinch a few days in advance and use a good breaker bar when it somes time to loosen them. They still might fight you though. Taking off the old crap is usually the hardest part. Keep a hammer handy too, it works well to tap the old bolts out. the new stuff should go on nice. You'll be glad you did it yourself when you're all done.

    The handiest tool I have for working on GM suspensions is a half-inch drive, 15/16's deep socket. It always seems that the end of the u-bolt sticks up just a little too far for a regular socket to fully tighten the nut. Oh yeah, air tools make the job WAY easier! [​IMG]

    Definately the deep well 15/16 1/2 drive. Even my deep well bottomed out right at the 150 ft/lbs mark. But my u-bolts were after market ones, not the ones that came with the lift. Don't ask, long story un-related to this application.
