This was the perfect video. Thank you! A couple of mine are making the same noise yours were and I have the same wear on the bottom side of the clutch gear set. Two done today, Two tomorrow with a test run. I laughed so hard watching you put the motor head on wrong and then catching it. Because of your troubles I took tons of pics. Then I still got confused.
I've got another one starting to make the same noise intermittently I guess I'll have to take that one apart at some point again too and see if I can stop that noise. Glad the video helped you, I sometimes imagine that a more organized workspace would be easier to work in LOL, but how was that real life LOL
Thanks for the comment, after I saw some guys using hammers and stuff on them, I thought I should probably make one myself to see if I really needed a hammer 😁
Thanks for the video. My 2001 Bigfoot camper has 4 4100 jacks on it. One is making a lot of noise in one area of it's travel. I ordered parts and will tackle this when they come in.
I'm tempted to add some white grease to the plastic guide bushings and the steel where they slide. It will slide easier with side load but it will also attract dust to stick to the grease. Did you lube the sliding interfaces at all?
the 4100 jack has smaller thrust bearing (1/2" x 15/16"), no brake, and it uses a plastic nut on the lead screw as opposed to recirculating balls. I'm wondering if oil or lithium grease would be best to use on the acme screw with plastic nut.
On the legs themselves? I'm having a hard time remembering where a plastic guide bushing is..... I'm thinking you are talking about the legs, but mine didn't have any plastic guides/slides on them. I think I saw a comment late so this is probably not correct or just confusing things.. but I'll leave it here anyway..
Didn't see this comment until just now, You're saying the ACME lead screw is nylon or plastic that's inside the leg? If so, that's probably a "DRY" lead screw they do not need lubrication as they provide their own by just regular wear I think. Is the lead screw making noise for you? I know you can pickup new dry lead screws in a few places.
Thank you so much for the video, I picked up a 2005 Host Tahoe from a bank repo auction and of course the jacks are a mess, your video saved my butt on re-assembly! I forgot how I took it apart lol
Thank you for the video!! just came across your channel. I picked up a truck camper yesterday with the happijac 4150, 4160 jacks. 3 of the 4 need work. Your video will help me take apart and put them back together. do you recall the part numbers of the bearing and o-ring? where did you order them from? I would like to order them. I'm also having issues with two of the four jacks (up front when I lifted the camper to load it into my truck) making a grinding sound and not lifting the camper 😵💫😵. I had to take weight off the jack and then lift almost like there wasn't enough power or there was too much weight to raise the camper. Not sure what to expect when i take them apart. Hoping it's just the gears. I haven't been able to find success in replacement parts though. any insight would be appreciated!
Hey Meck, sounds like you have a project ahead of you for sure, in regards to the front jacks grinding were they grinding or making a ratcheting sound? I picked the bearings and O rings up here locally in Denver, I can get you the part numbers as they should be able to be found online somewhere for sure.
What’s your conclusion??? Grease screw or oil only? Was screw greased from factory? Do you think a small hole drilled below the screw threads so lubricant can be sprayed onto screw gear periodically would be good?
Oil the ball screws with something like 3in1 and grease the Acme Screws with a light grease. I want to keep moisture out of where the screw is so I personally wouldnt put any holes in the legs.
Since my original question I did buy new jacks and opened up my broken/stripped Jack. The acme screw was Bone dry, rusty dusty. The motor gears on top of Jack had plenty of grease. I guess the threads the acme screw run through stripped and camper fell. Why they don’t add a spot to Lube the acme screw at the threads. Oh well great video on dis assembly.
@@NowWeRoam yes. This is the second Jack failure. First was a front jack, camper nose dived onto my truck. Lifted camper drove forward out from under camper then started lowering and pop, front passenger jack stripped lower leg just goes up into the top half. Second most recent almost all the way down and pop… rear jack stripped dropped only a few inch’s onto my jack stands would not lift up or go down. Second jack was what I did assembled.
I'm pretty sure the part number is "brake spring #149435", I have a feeling it's part that only they will have, have you tried to call lippert to see if they can source the spring for you?
Excellent video! Thank you for the help and giving us the part numbers!
No problem, I'm glad you found the video helpful!

That will be a fun camper, I like the floor plan. Thanks for reaching out happy roaming!
Great video. What is the part number of needle thrust bearings and brass washers? Where can i find these parts?
Hey Kevin, you'll find that info in the description.

The needle bearings are 1018's 1 bearing and 2 washers per jack

The O-Ring I used were 2-317-BUNA-70

THANK YOU! take care. @@NowWeRoam
it sounded like more of a clicking sound/ ratcheting@@NowWeRoam
@@NowWeRoam if it's making a ratcheting sound, can this be fixed? or what do you attribute the sound to?

Anyone know the part number or where someone might look for that brake spring?
I'm pretty sure the part number is "brake spring #149435", I have a feeling it's part that only they will have, have you tried to call lippert to see if they can source the spring for you?
