If you're going to be spending money on a track bar, you want the Currie 9120TJJ, not the JKS. Have you performed a dry steering test and watched each end of every link individually? That will direct you to the culprit. Don't assume that shops, even 'reputable' ones, know how to properly diagnose stuff like that.
While at the gas station a few weeks ago we did just that, inspected the joints on everything including the suspension. I had my CA bushings relaced last summer and no off roading since (rig was down all summer due to dual battery setup so I didn't wheel this year). I did stand there and look over the steering with the mechanic and watched key areas but then again I am not a "professional". I have seen rigs loose in the front while dry steering on pavement and mine has no sign of what I have witnessed before. I am going to continue to monitor my front end and will check it again this weekend.
I drive a BMW and they have tight steering compared to most vehilces and I want my rig to drive similar to that. The tighter the steering the happier I'll be.
I was able to replace the aluminum piece on my ORO Swayloc today, nice to have the swaybar connected again. I don't know if I would have gone with the ORO product had I known the replacement of this piece would be considered routine maintenance.
And finally fixed
I had to flex her out for the pin to line up with the sway bar, thank goodness rocks are a dime a dozen in Tahoe. Winterized the rig last week including a new windsheild, stud tires, oil change, rear diff changed and tire alignment
I have a new OME/ARB steering stabilizer on the way as well as some Rubicon Express rear sway bar extensions, will mount in a week or two. The tracbar is something I am looking into at this point, hopefully I can find one that will really tighten up my front end.
