Window lift arm question

[No. 13]

I have a window lift arm where the grey lift grasp on the end keeps coming off. It has a small threaded insert but no screw down plug to tighten. Usually it would be a small allen screw to tighten securely. All my windows have the same insert but no screw to tighten? Anyone know why?

How do you keeps these from falling off? Thanks.

I looked and actually have set screws in each handle.

Thanks for checking. I thought I did too. There is a little threaded brass insert, but no set screw. I went to Home Depot and picked up set screws that fit, but when I tighten them, the insert starts to pull out.

I mentioned this on another thread. Apparently all newer trailers do not have the set screws.
