Hello,
08 Marquis ..Recent left front air bags replaced and air leveling valve replaced. Done by HD truck shop...
Now when the coach is put into travel mode you can hear an air squeal and also when the coach is traveling and the front dips and comes up the same air trumpet or squeal is heard... Anyone have an explanation for this... Getting under the coach of course is difficult so before we did this... it so annoying while driving.. Thanks
