: Dumb question about jacking my truck up

I'm going to install some degree shims on my rear axle to change the pinion angle. I'm wondering if I'm going to be able to do this in the driveway with with a floor jack and some pretty high lift jack stands (24 inches I think)or if I have to use a lift. My plan was to lift both wheels off the ground from the diff and if the jack stands aren't high enough to keep them off I'll pull the wheels real quick and drop it onto the jackstands on the rear frame rails. Hopefully there will be enough room left to drop the rear end down and leave enough room to loosen my stock bottom facing U-bolt nuts. I've got chevy springs and 13 inch travel shocks and double shackles. I'm thinking no way can I do it! What if I lift it from the leaf spring right in front of the axle housing, then put the jack stand behing the axle housing on both sides? Seems kind of risky to me:confused: I figured someone has to have had the same problem. I've always had access to a lift but now it's a hassle to get to one.

Exactly. See that monster over there <--- in my avatar. Well I do all the work on it with nothing more than a bunch of jack stands and a floor jack. Chock the front wheels. Jack it up, pull the wheels off, let it down onto some low jackstands under the axle. Then jack up the frame to drop the axle. Put the frame on your higher stands. Drop the axle and do your work. Its that simple.

Kinda depends on what type of shim you get. The steel ones are best that bolt to the spring pack with the center pin. Another cheapie one is the aluminum that just slips inbetween the spring pack and the perch. If using the steel one, the axle has to roll about 3-4'' out of the way to get the existing bolt out and the new one in. In this case it may be better to leave the tires on and support the frame.

OK thanks for the advice you guys! I was planning on pulling the wheels (as I said in my post) but I thought that still may not be enough. As for the shims they are from 4 Crawler that bolt in.

Holy crap I just finished and I just barely was able to do it! I had 24 inch jackstands with 3 inches of wood underneath them and that still was not enough to to get the wheels off the ground when jacking it up under the diff. So I put the stands under the rear frame rails as high as they would go, jacked it up and pulled the wheels real quick then lowered it a few inches onto the stands. When I let the florr jack down ot went all the way down and there was still room to go! I left the jack under the pumpkin and used another jack to hold one side at a time up while I unbolted the U bolts. Luckily I could just barely fit my impact gun underneath (stupid toyota U bolts! got to get a flip kit!) Then I clamped the springs and had to jack them up to make room to get the leaf spring through bolts out. I cut the new through bolts before putting them in otherwise there was no room to get them in! THe double shackles really made this job a pain. I might take them off or pin them so I can lock them closed if I want to. Best part is the CV rear drive shaft I put in kicks ass! I guess the tapered shims are the key! No vibration, 70 feels like nothing. South Bay Driveline in SJ hooked me up!:smokin:
