Thank you Gil,
I jacked the chassis in front and behind the wheel to the height that the wheel was three inches above ground. The seller of coach told me, to try to move the bottom of the wheel out of the wheel well first. This finally worked, but still was very tight and I am concerned about putting it back.
At this point, I am trying to remove the old air bag. I loosened all screwes and removed the air fittings. The bag will not come out without removing the upper a-arm. I just looked at the 8 air bags I got from Prevost. All new bags are approx. 9"X 12 1/4". The old bag up front measures 10 1/2" high and 11" wide. I might have to check with Prevost to get an answer. It just does not look wright to me. I will keep you up how the project is progressing. Thank you again Gil
