How to temporarily let air out of rear air springs?
Hi all, i'm still rolling along with my 07 Rainier and 07 9-7x after many years.
My question is how can I temporarily let the air out of the rear air bags allowing the rear end to sag down with a trailer attached to it.
I have a large boat that needs to fit under a garage door and even with a large drop hitch (the lowest drop I can find), need a bit more drop to get the windshield under the door opening.
I only need to back it and take it out once per year and only for a few feet but can't push the boat by hand as it is too heavy for people to push. I'd want to let the air out, allow it to sag then pull the air compressor fuse for a bit so it doesn't fill up. I just don't know how or if it is possible to let the air out manually.
