download a service manual for a 625 leveling system from the hwh website. there should be a diagnostic section that covers your problem. if you have questions, please feel free to call me at 602-549-3638
i do work for hwh full time
i do not sell parts or solicit service vwork on this forum. i do diagnostics.
listen to doug
he doesnt get paid to answer all these posts.
he does it on his own. he doesnt solicit
service work or sell parts here
he does it, imo, because there is a need for
good substantiated answers, based on experience,
and the service manual
he sees many times the problems that an individual owner sees.
like i said, listen to doug. i havent seen a wrong answer yet.
i monitor this site, as well as others, and also answer questions.
there is no need to add my response, because it would be the same
i work for hwh full time. i also do not sell parts or service on this forum
geez, give it a rest. lots of folks make mistakes, they dont get nailed to the wall because of a spelling mistake. everyone knew what the op meant. everyone like a smart person, no one likes a smart ??? you dont make yourself look good by making someone else look bad.
you see this on every site. must be that someone has nothing else to contribute.
must be an english major
the jack extends because the fluid heats up and expands. if this is a new set of levelers, i would say that a hose had been run near a heat source. but its several years old, so i would say the springs are getting weak because of rust or road grime. you can either clean them with a wire brush or rust solvent, but if it was mine, i would replace them.
you can get them from hwh, stuarts in elkhart in, or on the internet.
the fluid doesnt have to be changed unless you have allowed it to be contaminated. it doesnt get very hot, it doesnt wear out and doesnt evaporate. it also has a 30 micron sock filter in the tank, in case something get into the tank while filling it.
if you dont have a visible leak, checking it once or twice a year is ok.

btw, im with doug on the blown hoses. hwh states in their manual that anytime
you have to go under the coach, that you use a jack stand or blocking.
its a safety issue that should never be overlooked, but is on a regular basis.
i work for hwh. i have worked on hwh jacks since 1973
hwh recommends either atf or wd 40. only.
some rv techs may have other ideas, but thats their opinion.
wd 40 is a solvent with fish oil in it as a small part of lubricant,
( i looked it up)
atf is the fluid that is used in the system. it cant hurt a thing on the jacks.
i know other mfg recommend other products, but
its your jacks, use what you think best.
i use dry silicone for a lot of things like my slide seals, my step and other areas that need lubrication. but not on my jacks.
when asked about age of your coach, just ask the age of the park.
and when was the last time it was upgraded. ive stayed in parks
with that rule, and it was marginal at best. the electric was
overloaded with all the coaches hooked to a couple of 110v feeds
supplying the whole park. only a few 50 amp services.
oh, and ask for pics if its over 10 years old.
i understand the purpose of the rule, but i have rules too.
my money my rules.
ps walmart doesnt ask the age of your coach
