The screw will not come completely out of the inner tube. It is built this way so you cannot overextend the jacks resulting in complete failure.
What I did with mine was I put my cordless drill onto the top end of the screw, and then grabbed handfulls of grease and held my hand with grease around the screw while I ran the screw back and forth into the inner tube and greased and greased and greased it.
If you are trying to remove the threaded rod top from the outer tube you have to remove the 3/16 by about 3/4 inch pin that is underneath the gear. It can sometimes be hard to see if there is grease there. Even a bit tricky to get it back into place upon attempting reassembly. Watch the instructions in great detail in the pictures.

Ditto this!!!
Some use water proof bearing grease...

Hello,
I keep a can of rust inhibitor spray on paint/rust guard, in the camper and touch spray surface rust, every time we go away. Use the Rust guard paint to spray other metal areas and also keep a can of black as well for touch-ups.

I do mine a little different but its worked for over 6 years. Taking a picture from the first post.

And just taking the motor off the top. In the above picture you can see there's room to use a White grease spray can and straw placing the straw next to these small openings around that inside SQ you can shoot this White Grease down onto the worm gear.
Sure beats tearing your jacks in pieces. And doing it this way It takes me less then an hour to do all 4 jacks with the camper sitting on the truck.
Plus less room for me to mess something up or leave a step out that could cause a camper to fall.

Thanks for the replies.
I've followed the directions, including removing the pin, but the leg assembly won't budge from the outer tube housing.
I've tried hammering on the center shaft, on the square metal piece that's visible 3.5 inches from the tube top, and on the foot of the leg assembly as the whole jack is hanging from the camper mount.
The reason I'm looking to re-lubricate the jack screw is that it turns very stiffly while making a grinding, squealing noise. With the jack off the camper I hear what sounds like sand (metal particles?) as I tip the jack upside down.
I've also tried the suggestion to use a spray white grease from the top instead of trying to get the leg assembly out, but the grease does not appear to flow into the screw assembly below the metal plate.
I appreciate any other suggestions you guys can make.
thanks,
Ted

Ted,
If you pulled the bearing off and the pin out of the shaft, it should come right out. Nothing else holds it in unless you have some different model jack.
The stiff turning and grinding noise sounds like the ball bearings in the recirculating ball mechanism are rusted like mine were, (see the pics I posted a while back of the inside of my jack.)
The rattling you hear is either flakes of rust or if some of the balls have fallen out.

I'll try this again. We are all a little befuddled as to what exactly doesn't come apart.
1) When you have your jack all together, did the inner square tube extend from the outer square tube out to maximum extension of 32 inches when you lifted the camper?
Perhaps the answer to this is NO, it did not, and that is the problem right there. Put a straight edge along each side of the outer tube and see if it might be bent a little. That may explain why the two square tubes do not come apart.
Recently I had to replace one of my jacks with a new one because I bent the inner tube about 15 degrees when it struck the ground. I took it to a machine shop and he tried his best to straighten it. But then it still would not go back inside the outer tube. Only then did we realize that the outer tube as well as the inner tube were bent. I tossed it then, only keeping the inner gears and parts as possible spares.

Many thanks to KKELLER14K. This is a most excellent thread. My problem was not related to lube or lack thereof. I had no broken or worn gears. The jack simply froze up and could not be extended or retracted with the motor or the manual crank. After removing the motor and top gears, the inside telescoping part containing the acme threaded rod would not budge. It finally took several minutes with a 6 lb. hammer being applied to the lower jack foot to remove the inner jack assembly.

Slivers of black paint that had been skimmed off of the jack and tightly compacted between the two sections had virtually welded the two pieces together. I then disassembled and lubed the other three jacks and none of them had any paint buildup.
Thanks to this topic, I am now very comfortable completely disassembling/reassembling the jack units. I also copied the tutorial and filed it with the owners manual for any future reference.

I'm so glad this has helped so many out....the info is easy to understand...when you see how it all works..it is not so bad to fix something that most anyone could do.

Wow, I find that interesting! I always thought the inside tube was suppose to float. The nylon pads at the bottom "inside" of the outer tube was there to center the inner tube.
This is something for us all to watch for now...
The process of disassy of the jacks is actually a simple process...
The main thing is making sure the shims and load bearings are put together in the proper sequence.
Thanks for posting your findings..

I certainly have some of the paint scraped off my inner tube as well... I wonder how this is happening?
