Topic: Noisy Lippert Level-up System fix ( marvmarcy -- Today, 09:18 AM)

...........................................
Lippert has finally offered a user fix for temperature related popping in their hydraulic four point and six point auto leveling systems used on many fifth wheel trailers. They determined the noise was caused by high stiction (static friction) in the hydraulic cylinders. Changing out a quart of hydraulic fluid for a quart of Torco RFF 15 ( 15 weight racing fork fluid) significantly reduces stiction and thereby greatly reduces the popping and jolting that many rv owners have felt. There is a recommended procedure to follow, and 10 wt fluid may also be used in cooler climates.
