HWH Jacks not straight - Problem?

Not an expert by any means on HWH stuff.

I noticed one of the jacks is at a slight angle to the side of the MH when extended. Thought it was loose and discovered the jacks are supported by a pivot so they will swivel a little bit. I understand how that can help with relieving stress as they are extended. But this one starts out at an angle, which will put sideways pressure of the other jack as it is raised.

Is there some sort of mechanism to get them to start out straight? I didn't find anything yet.

Mine do that all the time. In fact, if you look at my rear jacks from behind the coach, they appear knock-kneed. I assume this is a design feature.

I expect that it is an attempt to widen the stance and provide more stability. It does cause a disconcerting noise if you are parked on concrete and have extended the jacks to thier limits.

Have a nice day - Darrel

This brochure Features & Benefits of HWH® Leveling Systems from the HWH site describes (including pictures) how and why the jacks pivot like that.

Ha!
I just knew you'd chime in here Chris. Unless I missed it, that particular document really does not address the "angle" of the mounting. Most of us would surmise that it's an augmentation to the stabilization process. It's just like saw horses. All of those have the same angle to maximise stability when working on them. If you raise something, like a motorhome, with straight down jacks, there is less lateral stability.

But, with counter-force angle jacks, they're pushing against each other and thus, keeping things as stable as possible, almost regardless of the height.

Don't feel bad, it took me re-reading that 3 times before I noticed page 2.

Yep, they pivot otherwise they would stick as they went up and cause a lot of side force on the ram. Allowing them to pivot lessens the forces ("bending moment" in engineering speak).
