Another Level Up Problem

[Blenhardt]

We had the popping in our jack like many of you from the git go. After putting a quart of the recommended Cat anti-stichion oil in the popping seemed to be much better. However on this trip I don't have popping, we have a definite clunking, when set up, and the coach actually feels like it is sinking a quarter inch or so (probably not that much-but definite movement) when it "clunks". Seems to be occurring on more than one jack. I see no oil leaking. Anyone have this problem and what is the fix?? Wonder if a check valve is leaking?

I believe it is temperature changes. We have noticed that when the temp is stable - no popping or clunking. When temps are going up or down then pop and clunk.

Carefully check all your hydraulic line connections at the pump and out to the jacks. Also look to make sure you are not losing fluid around the seals of one or more jacks. I had a seal leakage around one of my front jacks and over a period of about 2 weeks our RW would slowly drop in the front by a degree or two. RW/Crossroads sent me a new jack. No problem since installing the new jack.
