Rear sway bar clunk

Note: this is not related to the rear axle clunk, different clunk

So, when riding over sharp bumps/terrain, I have a distinct clunk from the rear end. If you remove the rear sway bar, the noise is gone. The links seem fine, as do the bushings. Did a longer trail ride today, and it’s horribly annoying. Happens in uneven terrain or sharp bumps.

Anyone else have this issue? Car has about 500miles on it, and it started doing this relatively recently. It’s almost like a knocking, seems to resonate through the rear end. I had the rear axle clunk “fix” performed by my dealer, and that’s fine now. 2024 Northstar Ultimate 3 seater.

Ideas? My gut instinct is to replace the rear sway bar links with the shock therapy ones, but who knows if that’s the fix? There’s not a whole lot to go wrong with a sway bar setup?

I have what I would describe as a rear axle bind more than a clunk. You can hear it setting up for the release, almost like it's loading up then it lets go. It's pretty much been there since day one so I just kind of ignore it. Not sure if there is an easy fix or if it is normal but mine has always done it.

Someone had posted in another thread about torquing the sway bar bolts and it helped , I torque mine can’t remember the number but noise is greatly reduced.

So, it appears, after some test and tuning, the rear springs are moving ever so slightly on the spring perches or keepers at the top of the rear shocks. The noise is coming from the upper part of the rear shocks. We soaked them in Magic Tap cutting oil and the noise is almost gone. Also, rode with one swaybar link disconnected and the noise is pretty much gone. The one link disconnected doesn’t seem to affect high speed stability. Kind of a bandaid fix like the loctite rear axle fix, but at least it helped narrow the issue down. I’m going to pull the rear shocks and inspect them. Maybe buy the shock therapy spring kit?
