Thanks for all the input. As it turns out (after reading the manual once again in sloooow motion), I realized I was inadvertently short-circuiting the jack retraction cycle. I mistakenly thought I could terminate the retraction cycle when the green travel light illuminated. Evidently, this action prevented all of the air to be exhausted from the suspension, which upon reactivation of the leveling, forced trapped air to escape prior to jack deployment --- hence causing the very loud screeching noise. The owner's manual for the auto leveling system infers one can travel once the green travel light comes on. While this may be true, the subsequent leveling which follows will result in the screeching of escaping air prior to the jacks deploying. I am 99 % sure this is correct, but plan to verify tomorrow. Will confirm yea or nay later. Once again, thank's for all the replys. SamBar 2007 Allegro Bus 42QRP

We have a 43' 2007 Allegro Bus which has recently started emitting an extremely loud and piercing noise during the initial phase of auto leveling. It sounds very similar to the screeching when stretching the mouthpiece of a balloon - only 1000 times louder. HWH as advised us that it is not part of the Hydraulic System. The local Freightliner dealer has offered little help. Has anyone had this problem or can anyone offer help or advice as to what we should do to eliminate this noise. Sambar Ladson, SC
