I have to service one of my jack because of issues discussed here. A couple of questions before I start please...
1) I have manual 4150 jacks with no motor. Can I assume that the procedures described within will for the most part apply to manual jacks?
2) Before any disassembly, does the jack need to be in a fully retracted (up) position? My jack in question is really kinda' tight in the position it is in that I do not think I can retract it if that is necessary. Can I disassemble in the current partially extruded position?
thanks.
Sold the TC, previous owner of 2 NorthStar pop-ups & 2 Northstar Arrows...still have the truck:
2005 Dodge 3500 SRW, Qcab long bed, NV-6500, diesel, 4WD, Helwig, 9000XL,
Nitto 285/70/17 Terra Grapplers, Honda eu3000Is, custom overload spring perch spacers.

There is no reason you can't take it off where it is...as long as you can get it off. What is this on that it is not got a motor,..just curious?

Good to know that I can disassemble in the current position.
It does not have a motor... fully manual 4150's on all 4 corners of a Northstar Arrow camper as indicated in signature 2 posts above. I am going to tackle it this weekend.
Also- If anyone wants a document copy of the procedure, PM me with an e-address and I can forward a .docx. doc and PDF version for any member who would like one.

Man that's a lot of work doing it by hand...my first two had manual. Lucky for me the wife did help me out...but she was the one that said enough...I'm thinking yes!...we get a new bigger one! My last two had electric and it's a world of difference....but with electric motors comes a whole new set of issues. Best of luck...Don't forget that even if it looks good in there...it will be much smoother when it gets a little TLC.

It can be some work, but I have several 6x6 PT HT pieces of wood that I stack so that it is minimal travel of the jacks relative to the truck bed height. I set the jack down on logs and the crib stack makes it very sturdy even at that height:

My 1st truck camper had manual jacks. I got a socket for my cordless drill that fit like the crank. Mush easier than hand cranking.

My RT's are manual as well. The TC is set up for electric jacks but the heads are expensive (1500 bucks) and I can buy a lot of cordless drills for 1500. Mine are the same, up and down with a drill adapter. I run 2 cordless drills. my wife has one, I have the other, she is on one side, I'm on the other. Takes us about 5 minutes total from storage position (jacks retracted) to extended.
Maybe 'Santa' will send a set down the chimney this Christmas, who knows.

Was/ is there a consensus on the best type of grease to use for this repair?

I used boat trailer axle grease...
That was over 10 years ago... No more issues as of yet. I do use our jacks a lot!

Well, end of the line for my attempt to repair/ maintain the problem jack. The instructions were relatively easy. Getting th gear out was a little tough- I ended up attaching a needle-nose vice grip and then gently tapped the steel outside shaft and the gear popped off:

Once I got the gear off I thought I was home free to complete the chore...
But... the bottom leg would not extract from the housing! I think there was so much rust inside and it wedged between the inside of the outer shaft and outside of the inner shaft. There were deep scores in the paint of the inner shaft clear to the steel:

I tried tapping the lower leg out with a hammer to no success. Then I got a bigger persuader but it started to really tear up the foot pad:

I figured if I could at least get the jack apart I can weld up a new pad so I keep on pounding. But in all of the banging I only budged the lower leg about 9"... whatever is bound up inside will no longer allow it to move. At one pint I had already resigned myself that I will be buying a pair but I wanted to get this dang thing apart to see the inerds.
Who has the best prices on jacks?
