34TGA Leveling Jack Problem

Recently on a trip to Flordia I was getting ready to pull out and hit the AutoStore button on the HWH system. The front lights powered off quickly however the backs took 10 minutes to give me the all clear. Upon inspection I noticed the pumps are not working but they are being pulled up by the springs. Any ideas where to start or any owners have similar problems? Thanks.

The pumps do not return the jacks, the springs do. When you hit autoreturn all it does is open valves on the four hydraulic solenoids and lets the springs lift them up. If they are returning slowly , spray the cylinders with some spray silicone .

Mine do the exact same thing. Probably should call HWH and see if there is some sort of rate adjustment on the system.

Calling HWH is the right thing to do. The rear jacks on our 2012 TGA are always slower than the fronts, especially the left rear. In an effort to expedite the raising of the rear jacks and to try not to damage the solenoid by having it activated for a long period of time, I place an extra board under the rear jacks jacks. I always place a jack pad under all four jacks, so this means that there is an extra one under the rears.it helps a lot!

silverado574 check to s ee if there are greese zerks at the lower end of your jacks. wipe down the exposed cylinder shafts and spray with silicone lube. give each grease zerk 3 or four pumps of grease or less if you see grease coming out then run jacks up and down a few times and see if that helps

The HWH system has no grease fittings. Does your system have grease fittings on them?

Just to be clear on using a silicone lube on the levelers; make sure it is a dry lub. You don't want the pistons to attract dirt.

Yes mine does but I have power gear levelers. They may be different.
