I had a front airbag go bad. Started leaking and would not air up. Replaced (very easy) and now that side is 1.5 inches lower. There is only one leveling valve on front. Do I sim or replace other side? 6 days, 150 miles out of warranty. They are $300 a pop.
On my Alfa 36 foot RV they moved one rear valve to the front. 2 on front and 1 on rear. Had my Itasca Ellipse at Freightliner in S.C. this year for front end alignment and the right front is still higher than the left. It causes no steering or driving problems.
