    I noticed after our last trip that one of the stabilizer jacks was not parallel to the ground and had a lot of play. Checked the bolts that attach them to the frame and they were very loose and may have have eventually. come off. Repositioned the jack and tightened them up. Checked the other side and they were also quite loose. Just throwing that out there, may be something you want to add to your annual preventative maintenance checklist.

    After riding Harleys for years, I've learned that most any fastener can work itself loose over time.

    Things usually come loose about the time you take them for granted.

    Spring is here, camping season is upon us, it is time to lubricate your jacks! Here is my procedure:

    Jack up one side quite high, with the wheel off the ground a couple of inches. Don't jack the other side at the same time or the trailer will become unstable.
    Clean everything you can see with a rag. You don't have to get anal about it, just wipe off accumulated dust, previous lubrication, and other gunk. Most important is to wipe down the long jacking screw. Then apply some grease to the screw threads that are sticking out at each end. Don't put any grease on the threads in the middle of the jack as these will never be used and grease on them will only collect more crud (don's ask me how I know). I use heavy axle grease and apply with a small disposable glue brush.

    Also, check that the bolts holding the jacks to the trailer are tight (Thanks Randy!).

    Squirt a small amount of oil on each of the six pivots. It doesn't take much, just enough to be pulled into the moving parts. I use engine weight (5w30) oil in a squirt can.

    Raise the jack back up and wipe off any excess grease that squeezes out on the ends of the screw, and any oil the drips from the pivots. Now do the other side, then GO CAMPING!

    Excellent write-up! I would like to make one addition:

    As Rotus8 points out, the jack only threads through the rearmost part of the scissor. If it has been a while since the jack has been lowered: before lowering it, spray some WD-40 or lock lubricant onto the rearmost part of the screw (which is hidden away inside the rearmost part of the jack). Then take a old toothbrush to clean off any accumulated crud on the jack screw. You will likely want to do this several times as you extend the jack. Once the jack is fully extent, resume following Rotus8 directions.

    The above isn't absolutely necessary, but it will make it easier to extend the jack to do the recommended maintenance.

    Actually, at least on mine, it uses the rear most part and the very front of the thread, so clean off both front and back.

    It has only taken me this long to reply because I've been waiting for the right combination of available time and decent weather before crawling back under the camper. I hadn't realized that the jack screw exits from both ends (some models are fixed on one end, and I wasn't sure if Camp Inn had used those jacks on some models). I had visually checked that in the past, but obviously I wasn't in the correct vantage point to see the rear screw protruding. Greasing that end has further improved the ability to raise and lower the jack, so thank you for pointing that out to me.

    Since we live in our camper, we need to carry a lot of stuff with us. Which means we have to be selective about what we do and don't carry. One essential item is some graphite lube (Lock-Tite, etc), in order to keep all the locks working well. So we used that to lube the various joints of the jack. It is hard to say how well that will hold up over time, but it shouldn't attract dirt like most oils will. In about 4 years, we'll report back on how well that has worked for us (i.e. the next time that we do jack maintenance). ;-)

    I wonder about using bike chain wax that is intended for keeping the bike chain clean in the summer/dusty environment. Perhaps it would not be as durable and would need to be lubricated more frequently. I think it is called Clean Ride. Any opinions?

    Great thought! I suspect the main issue to be overcome is rainy conditions. Virtually anything you put on the jacks is likely to get washed out over time. Some lubes might last longer than others, but I will never be the person to volunteer to do that analysis. But newer chain lubes (which we also carry with us) would likely be at least as effective as the graphite. We chose to use the graphite because it was in a spray can, which meant that I didn't need to get as intimate with our jacks in order to apply the lube. ;-)
