Has anyone had one of their jacks only retract part way and then stop? The other 3 jacks retract completely and this jack starts to retract then stalls. If we "help" the offending jack past the stall spot it retracts completely. Camping World wanted $280 to look at it. Was wondering if anyone else has had the problem.

Sound like you may have a bent jack shaft. Try turning shaft when jack is about 1/2 way down. If it still sticks you may have to replace jack.

Have you sprayed the cylinders with silicone? They recommend that be done several times a year.

Do they recommend the same for the slide cylinders as well?

Thanks

Well, that stall spot makes me nervous, and Ron may be correct. Follow his suggestion, but also you may want to try:

If you have been camping in dusty or dirty environments you may want to do a crawl around and clean all the jacks with a shop cloth with a bit of ATF fluid on it, or silicon spray and then wipe the jack down. Seems like I have seen something like this after desert dust storm. Now I do a preemptive clean if I find myself in those conditions.

Also check the spring does not have any debris in it.

Not a problem right now, but sluggish in the cold - switch to Mercon V as the "Hydraulic Fluid" and that really helps when you have to pull your jacks up in the teens. When was the last time you flushed your Hydraulic Fluid?

My unit is 2005 GS 6340. Essentially it is 10 years old. I bought it two years ago. I assume that the hydraulic fluid has never been changed. What symptoms, if any, would I see if it is bad or going bad.

As always thanks for your time and advice

Bad oil can cause sluggish jacks and slides. Can also cause sticky valves. I replaced mine last February. Purchased 3 gallons of Dexron II (12 quarts) from Sams Club. With slides and Jack in retracted position. I sucked oil out of reservoir tank. Then filled with new oil. I then cycled slides in and out a couple of times. Did the same with jacks. Going full stroke a couple of times. Retracted the slides and jacks. Sucked all the oil out again. Refilled reservoir tank with fresh oil. Cycled slides and jacks again. Slide and jacks are working better. I plan on doing one more exchange of oil next winter.

How much oil did the reservoir hold? Sound like a great idea to me.

I had 1 quart left after doing this project of the 12 quarts bought. May have spilled some while filling reservoir.
