I have some WD40 that is silicone based (doesn't attract dirt). I had one jack that, at times, lacked about one inch coming all the way up. I extended all jacks and lubed them all with WD40 Silicone and now, even the sticky jack comes all the way up!

BTW, it doesn't hurt anything to use the control panel to lower and raise individual jacks.

I'll try that, never did it before. The original owner warned me against doing other than turning it on and pushing the auto button.

I don't use my auto level feature. I find that I can level the MH closer using the manual process. It won't hurt anything leveling or extending the jack manually. Remember that the HWH jacks move in pairs.

I did not know that, I thought that they acted independently in order to level the coach.

" Remember that the HWH jacks move in pairs. " It is my understanding that when you are using the auto level function, the jacks extend according to what is needed to level the coach. When using the control panel, you can do two at a time (front or rear) and they both move. Or, you can move any of them independently. I may be wrong since I always use auto level.

That is true about the new jacks, but the older 4 lever system works on each jack.

Not sure how old you are refering to, but my 2004 Newmar 625 jacks move in pairs. I can raise the front, raise the rear and raise the rear all of which extend the jacks in pairs.

I just had all 8 jack springs replaced at the HWH factory service center. Two guys did all eight springs in about 20 minutes!!

It just goes to show you... ya gotta know how to do it and have the right tools to do it with.

With HWH jacks it's impossible to do that since they work in pairs only. They call it Bi-Axis control as I remember.

If this is true, how in the world can KWH jacks ever actually level a coach? I have parked in several sites where only one corner of the site is lower or higher than the rest! Especially in Christian camps while volunteering.

When the jacks are deployed, the pair go down until the first one hits the ground. Once a jack hits the ground it takes more pressure to raise the coach with that jack, and since the other jack has not hit the ground yet, it takes less hydraulic pressure to continue down, so that jack continues to go down until it hits the ground at which time since both now take equal pressure to continue downward, it raises the coach evenly.

When you operate the jacks, whether manually or via the auto-level feature, there are ALWAYS 2 jacks running at the same time. Fronts, rears and sides always move together.

The system will not allow you to twist the chassis by operating only a single jack.

years ago, hwh mad a 4 lever and a 3 lever system. they did work one jack at a time. in the mid ninties, when the industry started making one piece windshields, and using glue in glass., hwh changed to the biaxis systems. it only uses two jacks and raises the coach on biaxis planes,
this levels the coach without twisting the chassis. we do not break windshields anymore, that are properly installed.
