Anth hey Anth, just wanted to add that having your suspension under load at static ride height is only necessary when you are setting the final position of the links and lever arm angles of the bar.
I found it heaps easier having the rear of mine up on stands with wheels off to replace the links and sway bar, noting I only fully torqued the mounting bracket bolts and loosely tightens the bar to end link nuts (heaps more room to work in). Then I put it on ramps/ wheel cribs at neutral ride height, levelled out the bar by adjusting the end link lengths and fully torqued one end link. I then moved to the other side and adjusted the link length so the bar was unloaded, then fully torqued that side.
Having said all that, if you're using fixed length links then I don't think it matters if the suspension is under load or not, just that the oem bar is not under tension when removing it, as all you can change is the angle of the ball joint pins. You want them to be as centred as possible and so your ability to change the new bar angle is pretty much zero after that.
Hope this helps!
