Last day of camping, "Bad Day at Black Rock" #2

[wilythek]

Well continuing my saga from my previous posts... I have a 1999 Mountain Aire, 3767 gasser. We stayed 1 week in one campground then a second week in another. I parked my motor home (on paved pad) at the 2nd CG and raised the jacks. The front jacks had to go almost to the upper limit.. When it did the front of the coach rocked to the left what felt like 2 feet, but in reality probably on a couple of inches...

The next day I had to reposition the coach and the same thing happened... In 5 years of ownership it never did that before. I inspected the front jacks and all appeared to be well, nothing appeared to be loose except for what I'd guess was normal left/right rocking of the jack of about 1" when it was in the up position.

Do I have a problem or could it be that that left/right rocking of the jacks have been frozen for years and finally broke free??? Any and all thoughts will be appreciated. Thank you.

Bill...

I wonder if you are low on fluid for your jack system. Can someone rock it or level it while you watch from the outside? Watch the jacks closely to see if the cyliner rods are moving in and out of the barrels- this would be an indication of air in the system. Also check the leveling system oil level. Just a thought.

When checking the oil level, should it be checked up or extended?

They should be up to avoid over filling

All four jacks have pivot points on jack mounts they are not stationary.
If you get under coach and with jack up you will see this when you move jack piston housing side to side.
What you may need to check is the bolts that hold the housing for jacks to chassis frame,you will also see bolts for two pivot point plates for jacks and those bolts need to be tight on both sides of housing, there are four bolts for each pivot point.
Your jacks are to stabilize the chassis frame, when you step on your entrance step you will rock the coach if you do not have a support under first step.
You should not over extend your jacks, you level each side rail Dependant where yellow light is.
In most cases yellow light will be on passenger side because its your heavier side so lift both front and rear jacks on that rail first.
Than lift drivers side rail until yellow light goes out.
Always lift each side rail with both front and rear jack together you do not want to twist the frame you could pop out your windshield other wise.
Each jack will lower to ground when one hits ground first it will wait until the other hits ground than both will raise the rail together until level on that side.
Your jack fluid in tank should be between the lines on shaft of bell vent with all jacks up.
IF you are on a uneven site do not ever lift rear tires of ground or your coach will slip forward damaging jacks.
I have two large rubber chocks that were supplied with my coach.

Thank-you! I have always wanted to know that. I will put that on my do list. Right now I am trying to fix my A/C. (changing thermostat) It is one of those projects I wish I would have NEVER started!!
