We have been having issues with stabilization. The JT Strongarm stabilizers were on the front jacks of our 5th wheel when we bought it new from the dealer. Now that we are having issues we have been looking at the install info and it appears the strongarms were not installed correctly. There are no bushings and they are attached on the jack legs in the 6th hole up from the bottom. Anyone else have theirs installed this way or have any suggestions??

Mine are installed at the bottom. As I recall that is what the instructions stated. Been 6 yrs since I installed them.In addition, when setting up you need to put pressure on them after you tighten the T handles. Tighten the T handles and then lower the jacks just enough to put pressure on the struts. If you can rattle the struts by shaking them by hand they are doing no good.For the rear struts I crank the stabilizers until the rear of the trailer rises just a little, tighten the T handles, and crank the stabilizer back just enough to put pressure on the strut.

I installed them as close to the bottom as possible, on one side I have it a bit higher because I have one leg with a screw adj. foot. and it doesn't allow me to go to the very bottom. I did call strongarm because I bought my set used at the swapmeet and didn't have all the details and they were very helpful. and after you are set up and level you tighten the SA and then lift the legs till you take the slack out of the SA. and you are good to go.

Having just installed these, I can say that the OP's installation might have been due to constraints of the 5er. The kit includes a lot of different parts/pieces for a more "universal" installation, but even then you may still have an issue making it all work. My front side-to-side and front curbside stabilizers went on exactly as instructions said. The front roadside stabilizer had to sit back pretty far and I had to develop a drop bracket in order for it to clear my sewer pipes. The rear stabilizers required me to install a section of uni-strut from side to side for the purpose of mounting to the top of the stabilizers.Not saying that any of this relates to the OP's issue, but it's worth taking a look at since the kits can only be "universal" to a certain extent ;-)

Didn't think about the need to put pressure on them though. Have to try that next time out.
