I've been running 9/16" bolts for a LONG time for trackbar and lower links all around and have never had one let go
AP, thanks for poking around and keeping up with me when you can! The bolt upgrade kit should give me worry free driving with the track bar. My current setup with the JKS bar and the first set of KOR bushings just sucks. I've had nothing but bad luck with this setup. The sleeve slips around sometimes, holes are slightly wallowed, and the bushings were real soft in that run of bushings I bought. So naturally, the track bar is currently able to move some even when tight. I have a feeling that *some* of the wobbles are to be blamed by this. Also why steering feels loose(r) then it should, if the bushings are moving around first, doesn't that effect the steering?
Just the other day, if you read this or not, I almost sh** myself coming back from Dad's to Mom's on the highway, the track bar bolt had come loose and jeep was really really wobbling on bumps. More so then its ever done to me before. At that point I was scared, mad, and happy I have the upgrade sitting at home. Also glad it didn't go to full on DW, just would wobble wobble 3 or 4 times longer then ever and then subside, thankfully. But scary.
Best yet, the new KOR revision of bushings I have on my bedroom floor are hard as a rock, fit uber snug in the sleeve and will fit extremely tight in the bar, to the point where hammering or pressing it in will be required. Then the sleeve fits super snug with the bolt. No more sleeve rolling around on the bolt!
Since the control arms, I've been able to dial caster to 6.5 degrees and not have any drive line vibes with the new shaft they built for me. That caster helps I'm sure over 4.2 degrees. I've got a few more things to do to Jeep. But I keep trying my best to "rollback" the odometer.
Thank you for your continued support and advice!
