Time for a Leveling System Upgrade?

The problem I had with mine was quite simple to fix. Removed the motors and taking off the end cap found that residual lubrication, dust, dirt, and particles from the brushes made the brushes stick in their holders. Was simply a matter of cleaning the brushes and brush holders to remove the crud and get the brushes free. Our coach was over 10 years old at the time and the brushes did not seem noticably worn, they were just binding enough in the holder to lose contact with the commutator and then the motor would not run. Was very intermittant failure. Once I cleaned them, they never failed again. We finally traded the coach for a new Winnebago with Lippert hydraulics, had a 2+ year battle with noisy jacks, Lippert finally relented and sent us new jacks. Noise now gone.
