When I did mine two winters ago, I didn't take my wheels off. I simple set the ride height around, then measured each corner when all four tires were on the ground. I jacked up one end and them remeasured the end that was still on the ground. If the side to side (Left/right) measurement differences did not change, then I knew that I was OK. For example, if the front of my car measured 25.5 (0" difference side to side) on each side and then I lifted it from the rear, and the new front side to side measurements remained a 0" difference (Obviously they wouldn't still be 25.5" with the rear in the air), then I knew that the rear heights were not influencing the front heights. If the measurements from side to side were 1/2" different from side to side with the rear end in the air, then I knew that the rear heights were effecting the front and I then slightly adjusted the fronts height and remeasured until they were even with the car in tri-pod mode.

I also track my car and since it brakes from 120mph in a straight line without pulling, then I know that the weights are not off by much. Much cheaper than the $400 I spent for the first corner balance years before.
