My one HWH jack on the passenger front will not go all the way up. I have to give it a push with a 2x4 and it will then go up. It works good going down not up.....please help

Very common issue with HWH jacks. There are two composite bushings inside the jack that swell up and the piston gets tight. I just went through this exact issue with the coach in my sig we bought a month ago. All four were not retracting.
If you are at all mechanically inclined the jacks are easy to remove. Unplug the switch wire on top - disconnect the hose on top - stick a pry bar through the bottom hook of one spring and pry it down and it will disengage from the pad - loosen the two 3/8" bolts that hold the plates that are holding the pins at the bottom enough so you can spread the two plates and the jack will drop right out. 10 minutes work after you study what is required.
Contact a local hydraulic repair shop and ask specifically if they have a history of fixing this tight bushing problem with HWH jacks. The shop that fixed mine said they slightly bored the bushings out to regain the needed clearance. The first shop I took a jack to spent two hours labor and could not get it apart. The second shop when they saw what I had just laughed and said they see those all the time and for about $200.00 each they fixed them and they work fine now.

You may also have weak return springs on that jack. HWH sells new tapered springs that are much better than the original. Less than $50.00

$50 will get you 2 sets (4 springs).

Thanks, i bought mine over 5 years ago and didn't remember the price. For me i would rather spend $25.00 for a set of springs instead of over $200.00 for someone to rebuild the jack to only find out you had weak springs. As they say K.I.S.S.
