It would also be good to hang the axles and make sure the driveshafts are safe from bind. Specifically the rear, because I know very well how mine came together. If what we believe it true, Chris's travel arc is shifted lower than mine is. But his rear output might also be a bit lower than mine is. The short Rubicon drive shaft doesn't like to hang too low.
Or just make an effort to not put both front or rear tires in the air...
I guess I was taking the lift and forklift testing at face value. If there is any sort of shop warranty on the work this would hopefully be covered. But yeah, for good measure I'd suggest taking the springs out and cycling the front and rear. Steering too.
I personally wouldn't want to break down on the trail or go back to that shop to check about any warranty.
