Rear Jack Issue

[wink1i]

99 Pace Arrow 37s. Front jacks seem to work fine,but when I switch to the rear jacks you hear the unit start to go but then it seems to just barely and fizzles.. Could this be the coach batteries? Need some insight.. The Living room slide always goes in n out just fine also.. Have had some trouble before with the front jacks but they seem to be okay now...

Put all the jacks down and lubricate them with silicon spray good.
And the rear jacks may have a grease zerk that 2-3 pumps will help them a lot.

Definitely clean and lube the hydraulic rams as the first step. The zerks on the jacks need grease (but not all Power Gear jacks models have the zerks).

If that doesn't do it, I would start looking at the valves for the rear jacks. They control the flow of hydraulic fluid to the individual jacks.

Found that one of the coach batteries is weak and needs to be changed. I will replace both batteries as to keep them the same. Is it correct for me to believe that this could be my problem... will start there first as I know I need new coach batteries...Sprayed all rams as directed, it just seems I run out of juice before I get the rear jacks down... Thank you for the help... You guys are great
