Question HWH front jacks (cylinders) don't retract

'98 Allegro with 210 series hydraulic jacks. Rear jacks seem fine, front ones are the issue. Here's the detail:

1) Put front to operate position and they attempt to go vertical. The issue, the cylinder didn't retract previously so the jack hits the ground before it completes vertical.
2) Back in store jacks go horizontal but again cylinders are still extended.
3) Put new fluid in as I had no clue as to the age of previous, Dexron ATF.
4) As only the front pair have the issue is this perhaps a valve? As I just recently acquired have no idea if this is a new or inherited issue.

I have one in front that does not always retrieve. I replaced the springs which helps some. I carry a short 2x4 to use as a lever for assistance, which has always worked. I'm hoping you find an answer.

I had a similar problem with one front jack. I finally decided to spray it with WD40 prior to retracting. It works like a charm. So well that I now spray all my jacks prior to retracting them. I found a large W D 40 can at Walmart that had a flexible steel hose that works well to get all around the jack. I hope this helps.

Rear Spring had a problem. Not an easy install, but I replaced. IF you end up doing it yourself call HWH assuming that is the jack and they can send you new springs. I have a trick for installing.

Successful trip

Thanks for all the jack tips. Basically have one that won't go full vertical but it's easy to push it down while the wife mans the joystick. Otherwise it works fine.

Only minor issue is one of the yellow lights stay one even when it's level. We can live with that.

hi david, my name is paul maddox. i do work for hwh corp. it sounds like you need try the wd-40 first. that helps in some cases. if that doesnt work, either new springs, or rebuild those two jacks. you can buy reman jacks on the internet, stuarts in indiana, or hwh corp.
this is not an offer to sell you parts, only an attempt to offer some suggestions.
email SERVICE@HWH.COM they will issue a rga number for you to send the jacks in and have them repaired. they only charge labor and the parts used to do the repair. this is much cheaper than replacing the jack. at the most, you will have to pay for a reman jack if they cant repair yours.
let me know if i can help paul maddox 602-549-3638
i do not sell parts or solicit service work on this forum. i only do diagnostics
