JKS Trackbar Bushing Advice (rear)

I have an 05 Rubicon that has a 2.5 suspension lift, 1 inch body lift, 1inch mml, and .75 isolators all around. About a year ago I purchased a set of control arms and a JKS (REAR) Trackbar (OGS153) that both have the two piece poly bushings. At this time I have no signs of death wobble.

Well I hate them .. they squeak in the summer and rattle in the winter. I cant determine if its the control arms or the trackbar. A quick look while it was on the lift for a repair I noticed the track bar bushings and some of the control arm bushings were in need of replacement. I didn't think to look for signs of it hitting the diff or gas tank skid...so im not sure if this is a problem.

Im just wondering if I should replace these bushings ... with something like the KOR superhard Rockwell durometer replacement poly bushings or just dump it.

As far as the arms they are going that's a no brainer ...

the bushing is squeaking and worn out is because it's constantly subjected to twisting & flexing under the suspension cycle.

If you replace it with something super hard/stiff, then those torsional/flex/twisting forces are going to be transferred to the mounts, which will rip them apart.

So, you want to use a track bar that will account for the torsion/twist/flexing by using a flex joint, yet provides the stability and clearances necessary. After going through the same issues, and major clearance issues with the same JKS track bar, I made my own custom bend track bar utilizing the original stock bar and a heim joint.

But for those not wanting to custom fab something, there are some better options. The new bend Currie rear track bar is supposed to address the clearance issues, and it uses a Currie Johnny Joint to account for the misalignment. It also requires using their relocation bracket.

Give these guys a call for more info:
Savvy Offroad

Regardless of the route you go, you will need to check the clearances at full bump. Here's how I did mine: Unlimited04's LJ Build - Page 24 - JeepForum.com

Am I the only one that finds Savvy's site confusing ... It appears there are two choices one with the bracket and the other without. One reads for TJ's and the other TJ's and LJ's and no specific lift height is listed...

The picture shows a track bar with one JJ and one poly .. but the add reads the opposite two JJ's.

Seems like this one will be the best fit ...

CE-9123N

Description: The Johnny Joint® rear trac bar for TJ Wranglers and LJ Unlimiteds includes all of the same features as Currie's trail and race proven Johnny Joint® front trac bar and is the perfect complementing unit to the front bar to optimize your TJ/LJ's articulation. This unit includes the heavy duty trac arm relocation bracket that allows the trac arm to be installed at the proper angle and position. The heavy duty steel bracket bolts onto the rear axle housing and relocates the trac bar pivot point. Bar is constructed of 1 1/4" heavy wall 4130 chrome moly tubing and features our 2" Johnny Joint® rod ends at both ends. NOTE: We prefer to see this kit used in TJ Wrangler applications due to the fact that the standard style trac bar bracket angles the trac bar back toward the gas tank, an area where TJ's have little clearnace. This new Currie bracket has angle built in to provide ample clearance. For LJ applications, where gas tank clearance is not an issue, our CE-9123 kit with the standard trac bar bracket will work just fine.
