How many people have had these binding issues just from having the tubes dirty and dry on the bottom where those 4 little pucks are?
Not had dirt cause any problem except to scratch the inner tube.
If your jacks are not mounted exactly vertical the will bind when lowering your camper. Going down that last 1-2 ft you can tell something is going on. Either jack screw lubrication or binding.
There was a fella on rv.net years ago that used a ABS or nylon pad for the feet of the jacks. He would tap the jack when he needed to relieve the binding. The jack would slide easily on the pad.
My front passenger jack was tilted out 2 deg and the drivers side was 1 deg.
Talk about groaning when trying to raise the camper...I shimmed the passenger side with washers and eliminated most of the binding.
I use one of these right on the jack.
You need to check for both tilt out or in and tilt front to back.
Most of the detectable binding will always be on the front jacks because they have the biggest load.

This makes a lot of sense to me. I can visually see the passenger front jack like this on my camper. It has always been like that, and has never groaned before though. I do plan to get all the jacks in alignment, can't hurt to be straight up and down, right.
