    After a 3 hour trail ride I see my passenger rear shock is unattached at the bottom for the 3rd time. Last time I loaded it with Loctite and figured I was good.

    I'm sure I heard this from someone else here as well. Is there a known solution?

    Drill a hole through the tip of the stud and run a cotter pin through it.

    These shocks are not installed like this. They bolt to the spring plate with a 1/2" (i think) bolt. The blot comes loose and the shock dangles/drags.

    Here is the front without the shocks installed. The rear is just the same.

    I think I can drill a hole through the mount and into the bolt and put a cotter pin or set screw of some type in there.

    Is there a sleeve/tube/spacer over the bolt, inside the rubber bushing? I'd torque solid against that.

    That bolt design seems like a bad idea. I can see why they come loose. That’s a lot of shear stress against the threads, especially if there’s no sleeve to tighten against like Pete mentioned. I’d be inclined to weld a stud in place and use a nut. Take those stressed threads out of the equation.

    Zilla has this same problem....... Steve has not yet had a problem but then again he ripped his shocks off before they had a chance to loosen up......

    I think I’ll go for the easy fix for now. Drill and pin.

    Mine has bolt on lower shock mounts...been there for years. Loctite (blue i think) was all I used.

    You sure you aren't bottoming out the shocks on full compression? That can make bolt-on shock pins loosen.

    I have the same rocky road plates, guess I better have a look. As far as I know I haven’t had a problem in about 3,000 miles.

    I had one bend and one come loose. I replaced both fronts with grade 8 bolts. My rear came loose. I tighten it and haven't had a problem since. Seems long term the problem my go away. I think I have the oldest conversion.

    The RR plates are pretty stout. You could probably drill and tap a hole for a set screw on the shock bolt threads. This is what we will do to Steve's if he keeps shocks on the jeep long enough for the bolts to loosen up.....

    Agreed! They should know better than manufacturing something like that. :(
