Just got the answer from Hapijac, they answered within a day! They sell the upper assy as a kit for 42 dollars. It includes all what is needed to fix the thing, bearing and washer, wrap clutch spring, connecting barrel and square plate.

They also sell everything else you need to fix your jack.


I am impressed! Kudos to Hjac!

It does seem that the rear jacks are a lot more reliable but they do not have to do the work that our front jacks do.

They sold me the parts I needed. Shouldn't be an issue


Thanks, that will make rebuild easier.

Well, did not work as well for the other three. One has the spring broken, one has the bearing washer broken and worn, the other is rusted in and out but the mechanism works good. Hope I can order some spare parts from HappiJac.

The o ring between the barrel and bottom of the head are also all torn apart. I believe it brakes up like that when you get them to snug when they are up, it probably squeze the o ring too much. This cause the o ring to get in between the screw and the head and it created lots of dragging.

HOpe the company will answer my request, otherwise I will not be a happy camper. Camper is only 5 years old without any abuse.

Got the happy jack apart, thanks for the thread. Mine was pretty good inside, well greased, gear shaft oily. I had to straighten the outer tube, It got hooked by the tie down when I was pulling away. I had a small curve in the outer tube but the inner one was ok, so it was binding a bit. I placed the tube on the ciment floor and a piece of wood over top and I hit it with a sledge hammer. It got back almost perfectly straight. The inner tube slides easily inside now. Just have to paint it and put it back on the camper, hope it works.

Hi Jim...

I was also wondering what instructions they gave Devildog, I did mine the way you showed me and it worked very well...

There was talk that the company would not give our the instructions due to so called liability issues...


That is absolutely correct! We will have to wait on Devildog to tell us what Hjac said and actually what he did.

I will say this, after I lubed my jacks the first time I have been a happi jac guy. I have done them 2 times.

Almost 14 years now... and I use the cr** out of mine.
I have had to sand some places on the outside tubes from rocks chipping the paint and then rust sets in... Otherwise... No other problems.

Happi jack sent me the pictures and instructions my jacks worked better than new afterwards the only thing I did different was I used marine grease inside the jacks I also found that the big zip top food storage bags fit nicely over the jacks and stayed in place while the camper was stored


I assume the manufacturer pictures and instructions are detailed, how do the company procedures compare to the procedures used here on the forum for disassembly and lubrication of the jacks.


Devildog has a good question.... I never knew that HJac folks would tell nor show anyone how to take apart their jacks and lube them the way we here on this thread have....

Woodhog, did they tell you to totally disassemble your jacks or did they just tell you to put the grease on the gears where the motor interfaces??

We all know that is not the fix, nor the proper maintenance procedure.
