Two leveling jack will not go down

OK dougrainer I tried it with all four T handles opened and all four extended. I hit the store button and only the two that were working previously retracted and the two that were not working are now stuck in the down position. I hit the off button and turned of the ignition switch so I do not burn out the other two. I have not closed the T handles. I assume they are stuck because they need to be lubed or something? Now what? :)

Thanks!

NOT good news. The 2 that will not retract have BAD internal seals and they are sticking. Leave the T handles OPEN. You will have to get either a floor jack or a long wood or metal pole to lever up the stuck jacks. IF your unit has air bags, start the engine and let the RV raise up when the air bags inflate. That should give you enough room to get under the stuck jacks unless you only extended them a few inches on your test. With the T handles OPEN, the jacks will retract when you lever them up with a lever or floor jack. Once fully retracted, close all 4 T handles. You will have to either replace those 2 bad jacks from HWH or remove them and send back to HWH for rebuild. Some local Hydraulic shops may be able to rebuild them also. You will also have to replace both solenoids that control those jacks. The previous owner KNEW of this problem. You will have to get the solenoids from HWH. If you cannot find a local shop to rebuild, you remove the cylinders and ship back for rebuild. ON the jacks are a Model number called a AP number. You really need that number of of each jack. The T handle solenoids are all basically the same. The NEW solenoids have a spring loaded release and no T handle. The front Jacks will be one model(the same AP number) The Rear Jacks are usually a heavier model but they will have the same AP number. Since your unit is 18 years old, I would also replace all 8 jack springs. Your old springs are probably rusted and have lost a lot of tensile strength. When you have a HWH jack, you can PUSH a GOOD jack to full retraction with just your hand. Doug
