A couple of questions:
- How high did you have to jack up the rear?
- Is that a multi step process of jacking up left a couple of inches, then right and then back to left...
- Any issues / danger with only jacking up the rear?
Thanks
JJ,
Build ramps to back onto. An extra 10~12inches should do, and then turn the rear up and block it there. (If an airspring (air bag) blows, this thing can squash you like a bug. Remember to chock the front both ways.
I cheat. I have a 7K car lift that I usually use to lift the bogies. I can't lift it very far because the barn roof is in the way.
The problem with jacking the rear a little at a time is that you really have to jack where you want to block unless you have the OE jack. Be careful how and where you jack. Bud Sargent, a VP of Thetford and a GM expatriot, got one of the first coaches. It went to a local GMC dealer for service and they put it on a truck lift and bent it so the door would not close. I got to go and pick up the replacement coach.
Other thing to not do is put the front on something solid, jack stands or a block frame and then jack one side of the rear. This can break things.
