It isn't clear in Slee's instructions but can I change out the upper control arms on the vehicle without resting the frame on jackstands. It seems like this is the case but I'm not sure. Thanks for the help.
I'm sure it "could" be done, but I wouldn't suggest it. Putting safety issues aside, you're going to want to be able to twist that axle a little bit to get things to line up, and that's a lot easier to do when it's unloaded... also raising and lowering the axle can help too. But better answer is it's much safer to put some big jack stands on the frame. I think it will make the install easier too. hth...
The axle's gonna try to rotate, so getting the bolts in is gonna be difficult. Not to mention it's painfully stupid to do suspension work without jack stands supporting the weight of the truck. Maybe even Darwin-award stupid.
Yeah, one at a time would probably work. Me, I jack the truck up high enough that I don't have to struggle and bang my elbows and drag my stomach across the driveline, but I'm bigger than average. Plus I like to put them in where I think they need to go and adjust from there, but they're not terribly hard to adjust in place. The thought of working on my suspension without jackstands makes me nervous, and there's no reason for me not to use them.
