Rear Suspension Lower Trailing Arm Removal

[EddieC]

Can I take it off with the vehicle weight on the tires?

yes, if you can reach the bolt (i think on the drivers side you have to move the parking brake cable) but i'm just going off of memory)
just be aware that due to the dynamics of how the suspension is, IF you take the bolt out, change the arm, whatever it might not go right back in. The fix is to start it up and either turn the front wheels one way or another if that does not work then put it in gear and do the same but move forward or backward a hair as well while turning.
same thing can happen with wheels off the ground.
it's just due to how the frame works, there could be a tiny bit of pressure on the arm and when the bolt is removed if it then moves even just a hair it can make it so the bolt wont go right back in. not a big deal just extra work sometimes

Yes Seriously.
Haynes Manual says to jack the wheels off the ground, etc, etc.

Wes's input is helpful for what I need to accomplish with the least strain.

This was exactly my experience installing two lift kits (two different Tahoes). Had to wrestle to get the bolts back it. I didn't try the 'put it in drive' method, but did use floor jacks to change the dynamics and align the holes.

a couple times mine has fought me so after trying different things with no luck I just put it in drive turned the wheel and put it back in park and that worked
I suppose a jack at the right angle would work just as well but mine needed left/right adjustment up/down didn't work
