sc, the cylinder need rebuilding or replacing.
at fmca rallies, like the one in perry ga, there are lots of guys with 2x4's.
they know what has to be done, but wont do it. they keep putting up with it, hoping there is some miracle cure, but it just won't happen.
the solution is to cut loose with some money and repair the problem.
thats what i do.on my coach.
call hwh and get a tracking number. send it in to be repaired. unless its bent, the cost is way less than a new jack. the most they will charge is for a reman jack.
even at that its still cheaper.
if you just want a reman cylinder, call chuck stuart in elkhart. his prices are the same as hwh.
