Figuring out track bars

Paulie · Mar 1, 2007

Working on getting Arons cherokee finished and we got the diff in place, everything pretty much re-done. Now when i got the track bar back on in place, it seems like its alittle steep. I tried to put the diff at ride height but never measured it up to be exact. Is the look of this going to be a problem. our solution we figured was to locate the mount on the frame down a tad to make the track bar flat. im not real good with making the track bars work out right. i need someones help

You could move the frame mount down a little. Or you could kink the trac bar a bit.

From what I understand, you want the force at the mounting points to be horizontal, not vertical at all. So a little "s" bend for lack of a better term may be the ticket to avoiding death wobble.

Hopefully someone more eloquent than I can describe that better.

Yeah i just looked at kellys thread on his grand and his is bent like a Z

any thoughts of bringing it down to this area, this is what we were thinking of doing.

If you do, make sure you reinforce the unibody and mount right there. That just adds to the fulcrum and the force to tear the mount off the "frame".

FiFo's Trac bar is about that. His Johnny joint wobbles too. (At the middle near the jamb nut, the mount has to be retightned as well)I have no Idea why he doesn't have death wobble.

Make it longer via changing the mounting areas. By doing so it will make things better all around.

the front 3 ft of framerail is reinforced with 1/4" plate

we are going to re-build the frame mount a lot lower so it flattens out the track bar a lot more. we'll start with that and see how it works before making a new track bar that needs bending

FWIW when you do that you will have bump-steer.
Technically you want the track rod that the drag link parallel.
This is not that important if it ain't a DD.

it will have bump-steer the way its setting now.

Putting "S" bends will only help for clearance and will not make it work any different. By the picture it looks to me like you need to lower that thing down some. As said above, the track bar should be paralell to the drag link.

hows this........

at full compression: (track bar mount is obviously temporary)

at Full droop:

Is it hitting the pumpkin on full compression? Looks better now. That divers-side mount will have a lot of leverage on it so overbuild the hell out of it.

nope. doesnt touch the diff. and yeah we are gonna use 3/8" thick steel for the bracket and gussets, so it will be plenty beef

Way better.

Burn it. Er i meen weld it up...Got jam nuts yet?

Follow the drag link and your golden...

In the first pic, is it an optical illusion or are the coils bowed? Like the lower coil mounting surfaces are setup wider than the upper ones?

Paulie · Mar 8, 2007

thats when the diff wasnt square, they set fine

also i plan on running a track bar brace from the pass side to the track bar bracket, dout it can break now.
