Hi, I've got some tires I need to put on this 91 SSE w/ the rear self-leveling system. Only problem is: Car is off the road and in storage, so I need to go put the car on blocks while I take the wheels to my garage to mount and balance. I'm only going to do 2 Wheels at a time, so the car would be sitting for about 24 hours with 2 wheels on it and blocks under the oppisite side. Now, I've been told two things that I need answered before I go about this ordeal: 1. In this Generation Bonneville; the Self-Leveling operates ALWAYS, meaning even when the vehicles Off, NO Key, No Drivers. True? and 2. Because of 1 the car'* self-leveling system should be disengaged before going up on a lift (or blocks in this case) so as to not blow out the rear Air Suspension. Whats the Deal and what do you gentlemen recommend?

THANKS GUYS,
ROB

I've had mine up for a week without doing anything detrimental to the rear leveling. Maybe I got lucky, but I don't know why it would hurt it.

If you wanted to be safe, the leveling has a fuse. Pull it.
