Leaking of leveling jacks

[A.G Larry]

Does anybody have an idea on the cost of replacing seals on leveling jack (power gear) on a 2000 Tradewinds 7371? Also, does anyone know the life expectancy on the airbags under normal conditions with 68,000 miles on the same unit? Thanks in advance for any advice and I really appreciate reading all the posts on this website.

I recently had a right rear jack replaced at CW, claim that it's cheaper than replacing seals unless doing it yourself. jack was $500 plus 2 hours labor costs. not sure if i agree with them but new jack working ok.
cannot help with air bags question.

Regarding your air bag question.......I had my bags changed this morning. they were the original bags on an '02 chassis. I changed them as during my inspection I noticed quite a bit of weather cracking in the surface of the bags. The coach has about 72000 miles.
While at the shop waiting (took almost 2 hours for all 4 bags) a trucker came in and we were talking. He said he changes his trucks bags every 4 years. Of course he drives many more miles per year than we do. I imagine the bags flexing shortens the life moreso than time. But, I don't know how much flexing is too much. You probably could inspect them and then make a decision based on what they look like.

If you can remove and reinstall them yourself and the shaft isn't scared you can get the cyliders rebuilt for a lot less than $500. Just look for a HYD repaire shop and many of them will do the labor too. With labor rates around $100 an hour or more I prefer to do the labor myself when I can.

I'm getting ready to relpace the seals in one of mine. I haven't priced a seal kit yet, but can't imagine it costing over $50 for the parts. I have a manual on how to do this if you want to tackle it yourself.

Air bags can last over 20 plus years.
No need to replace until they get a leak. Even then the air compressor will probably keep up with the leak until it is replaced.

I have changed both of my front PG jack seals myself.
Parts less then $80. I used a floor jack to lower and raise them.

If you have grease zerks on your jacks, try pumping some Lithium grease into the zerks. That will often stop small leaks. The grease is used to lubricate the seal, at least that's true on Power Gear jacks.

I've installed seal kits on two of the jacks on my 2005 8360. It was pretty easy and very messy. The seal kits come with big new steel seal holders that unscrew from the bottom of the jack, various seals and friction rings. I've found that the job is easier if you loosen the big seal holder [the thing with the zerk fitting] before removing the jack from the coach frame. Don't remove it all the way, just loosen it. You can get more leverage this way without trying to hold the jack in a vice to remove the big seal holder. Most of the seal replacements are pretty self explanatory when you follow the guide that comes with seal kit. Make sure that you measure the thickness of the old friction ring that came out of your old seal holder and replace it using the new one of the same thickness. The seal kits cost about 175.00 give or take a few bucks. Your total savings will be a lot unless you ruin a nice shirt and jeans along the way.

Hope this helps.

I had both rear jacks rebuilt with new seals by a mobile RV repair for $550.

Thanks for the link and tips. Saved both.

Do you still need the heat when it is still on the coach?

Yeah, thats the price I was quoted per kit. I need to do 3 !
Is the new seal holder important? I was thinking of just taking mine to a hydraulic repair shop, and having them replace the seals .

If red loctite was used, you probably will.
