    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.

    (Thanks for the up vote)
