power gear 4 leg leveling problem

[abwatac]

I have a 1998 Bounder with a 4 jack leveling system (power gear), I do everything the same way as always I drop the front jacks on the ground just touching and go to lower the rear and as soon as they touch the ground the front starts to (jacks) lift the front also when you try to bring one of the rear sides up to level (left to right or right to left) the front jacks lift. Just need to be pointed in the right direction I am getting tired of how the dealers rip me off always selling me new systems for everything that breaks.

The front jacks in your system operate as a connected pair via a shared hydraulic line. That assures they will never twist the frame by lifting one corner too much. When your rear jacks start pushing one side or the other up, the front reacts by shifting toward one side or the other to balance the rear action. In essence, one side goes up a little and the other side down a little. That is "working as designed".

Put the fronts down enough to get a bit of weight on them. Use the rears to raise as needed and to level side-to-side. Then use the fronts to lift the front as much as needed. The system actually works quite well. You may need a couple of cycles to fine tune, adjusting the rears a bit more, then the fronts again, etc.

From the sounds of it you have at least one, possibly two, valves that are not functioning properly.... I have at least one myself.

But let me ask some questions: You say that the front jacks go down JUST TILL THEY TOUCH and then they go down no farther? This would suggest to me a stuck open of partially open DUMP valve.

But when you put the rears down they go down, but then the fronts (Without being told to) continue down... Well, that's the front leg valve .. But it rules out the stuck dump valve

This brings up the posibility of a control board issue.

I do as I always do, put some weigh on front maybe lift the front about half inch, then I go to the rear and start to put them down to lift rear and as soon as they hit ground the front starts to lift. if I try to level side to side the front starts lifting.
