Just purchased an 07 Allegro Bus with HWH automatic levelors. They work fine, but when activated to level the coach, they screech loud enough to wake the dead. HELP please.
Couple years ago, my POWERGEAR did the same thing. Outreageous squeal when deploying the jacks, (but the jacks held) and silence when bringing them up. Turned out to be the main bearing on top of the motor. Available at any auto parts store for about 20 bucks. However, I had to remove the pump/motor and reservior. And upon reassembly, I slathered everything in that area with lithium grease. I hope yours is as "easy" ($$$) as that.
