I have a 2005 Winnebago Journey 39K, with HWH 325 series levelers.
The passenger rear leveler is very slow (over 3 minutes) in retracting. I tried getting it serviced and they did find a leak at the front controller from a pinched "O" ring. After the completed repair, I tried them out and the rear leveler still was very slow in retracting. In fact the mechanic, used a board to push it up. They told me it needed new springs, but to order them from Winnebago as they would charge me twice as much.
Well I ordered new springs, actually all 4 sets, since Winnebago had the wrong part # on their site. Next day they told me the right part and I ordered the rear springs. Not terribly expensive at around $35.00 per set.
I installed them all myself rather than ship the front ones back. Now the 3 levelers come in in around 30-45 seconds, but the passenger rear leveler, takes about 3 minutes to retract and the light go out.
I have been told it is either air in the line or a faulty/clogged solenoid.
Anyone have any thoughts on this?
