What is a Track Bar ?

Just what it says. I guess it's time to show my ignorance, but I see this term a lot and am not exactly sure what it refers to.

I know that control arms locate an axel in for to aft position. Does the above refer to something that controls side to side movement?

It keeps your axle centered under your jeep and prevents it from moving side to side when hitting bumps.

An always helpful picture explains it best.

In a word, exactly.

track bar

I have a 92 YJ that I received to place under my 90 YJ body and I notice that the rear track bar is missing or cut out? There is a bracket on the rear driver side axle that is cut and the bar is cut after the joint on the pass side rear frame. Do I need to replace it. What is the function?

front track bar

Separate question on a track bar... on my 03 TJ I have a lot of play on the ball joint that is on the front track bar. I had the frame lifted a couple of years ago and I dont know if this was installed as an after market track bar or the original? I have a frequent death rock when my pass front tire hits a hole and sets it off. The ball joint that has slack is a fixed ball once installed, it is not a greased movable ball joint. The play I have when I turn the steering wheel and it is at rest on the ground is approx. 1/16". Can I just get another ball joint which has threaded studs on both sides?

on a YJ, a track bar is not required as it is leaf sprung. it does help handling, but is not a Must have on something with leaf springs, as the springs themselves limit lateral movement.

it sounds as if it may be a heim joint, not a ball joint. a ball joint will only have a stud on one side, where a heim joint uses a through bolt.

You'll get better help posting those questions in the YJ and TJ sections of the forum rather than reviving a 6 year old dead thread about ZJ's.

Underpowered has it straight though. You should be able to get a replacement end for that track bar either from the original manufacturer or somebody like ruffstuff.

track bar

Yes it is a heim joint you are correct I thought it was a ball joint. If you can see the image I posted of my current part. It appears to be a metal on metal ball and socket no bushing or bering just the type that you articulate the bar during installation and lock it into place. I dont believe it is designed to move on that side? If it is supposed to swivel at all then the friction it encountered just wore it to the point that I have a lot of space around the ball and this is what is causing my death rock?

There should be no play. Just tight misalignment.

it does not lock into place. Heim Joints are supposed to swivel and move. they offer a greater range of motion than a ball joint. It is not supposed to have any gap around it however. most likely it is simply worn out, as they do not last very long on a daily driven vehicle. general rule of thumb is they only last about 10k miles.
