Those are just a different style, I have a JKS and it has the bolt through style. Currie has the same style, you have to drill out the mounting hole, so no going back.
Exactly..all tj track bars are the same basically... Your number one aftermarket is jks in my opinion, I have some company's heim joint style on my 2006 Rubi ..and while it's more rigid it gets dry and pops it leans toward being just a hair twitchy .
Tow and caster can come into play on all this , and they do matter .
Based on my experience if you want the Jeep to drive great.. I'm talking 65 miles an hour with big tires and one finger and be able to look off the road and back to the road and still be in the same place... You've got to have everything in great shape. Every thing from tire to tire , and the back has to be right to . Also don't forget sway bar links .
One thing folks miss is things can be loose and appear tight at rest ..when a vehicle is in motion , tremendous forces are at play.
The track bar can cause a lot of grief way before anything is to the death wobble stage as well . I think of it as a dominant component on all front ends that are designed with them.
I would almost rather have death wobble and knock it in the head then bad handling I can't figure out.
A dry test and watching the track bar closely will tell you real quick if the track bar has got excessive movement at either end ... The bushings are going to flex some but other than that nothing else needs to be going on. It needs to move like 1/8 +- when dry tested by turning the wheel , and that's no hard .
The solution to a lot of these situations isn't necessarily a completely brand new front end... But the problem most of us run into is components get replaced at different intervals over time so you end up with a front-end that has parts that vary from being 1 to 15 years old maybe...
I like everything on the front end to at least be consistently dated, or all have similar mileage ...so you aren't playing whack a mole .
The other side is some components wear faster than others typically ..like tie rod ends may wear faster than ball joints . So everything has to be inspected .
Lastly , the hub unit bearings in front can affect tracking a tad if worn also.
These aren't high maintenance vehicles ..they are 14-22 year old vehicles that often don't see enough maintenance , and plenty of mud , dirt, sand and water .
Don't give up ..to have a Jeep that drives awesome is entirely possible .
