HWH Levelers-Final Fix?

I took a HWH jack that would not retract to a local hydraulic repair shop. They told me HWH uses Phenolic bushings inside the jack and the bushing will swell up from contact with the hydraulic fluid. They disassemble the cylinder and made a slight cut off of the bushings on their lathe. That relieved the binding from the bushing being too tight. That was 3 years ago and they still retract fine. Cost was about $200.00 per cylinder. They said they had done many of them.

Only reason to replace a jack is if it's bent, otherwise look for weak springs.
You can interchange the springs with another to isolate the problem. If it still won't retract, then good chance it's bent.

If you can get all jacks up check the fluid level FIRST.After fill up run up then down a few times. also check the springs, mite have a week spring, a spring is cheeper than a cylinder.

yep, i had a reluctant jack and dropped it on a 2 x 4 to use to start prying it up. eventually had to have a mechanic remove the jack so I could continue to the next camping world for replacement. when they start to chatter replace them.
