Re-adjusting with the car on drive-up ramps will affect axle positioning by a very small amount, probably not by enough to notice. But I'd suggest using the lowest ramps that still let you get under and adjust (even if you have to make them up from 2 x 10's), or that you intentionally offset the axle a really tiny bit toward the passenger side unless you're lowered. "A really tiny bit" is 1/32" or less.
I hope that you did not use high strength Locktite (the red stuff). If you did, you'll need to heat the Locktited joint.
I did use the red loctite before I realized it was off, bad decision on my part, that's why I'm asking if 1/4" is a huge issue. The thing is, I could drop it off on the passanger side and adjust it but I'm having issues getting the sway bar support out if the way. That coupled with the car being low and difficult to maneuver under. So would driving the rear end up on ramps make the car sit differently than normal ride height?
