Steering Bar bowing / flexing

Last night in doing my tightning over haul, i jacked up the jeep and let the front suspension hang in mid air so I could tighten everything up like crazy w/ my impact gun.


While checking the wheel bearings to make sure there wasnt any play I turned the ignition to the "on position" and let the steering wheel freely spin. I started moving the drivers side wheel side to side like it was turning and noticed that this bar (as shown below) is actually bowing / flexing just by shaking it slightly by hand. If I am able to do this with just a few lbs of force by hand I can only only imagine the forces that are put on it at 70mph while driving down the road hitting a pot hole.



I am not sure what this bar is called but it connects the Steering gear box > the stablizer shock which connects to the tie rods to turn the wheels.



Is this common or a known issue? Or know of any way to fix this?

or a drop pitman arm

You're at the limit of the joint on the pitman arm on the steering box when you turn to the left its lifting the bar "bending/flexing" as you see it.

So basically because of the lift you are saying that the steering bar (drag link) is maxed out and doesnt have enough threads to support the steering as origionally designed?

As a result its flexing / bending causing the store / release of energy to contribute to the death wobble?

Just trying to compaire between his and mine..

Mine stock,



after the HD Upgrade:

that bar shouldnt be bowing. I have the RE 3.5 kit that came out to 4.something inches. and i have no issues with my steering. its as tight as the day i first bought the jeep stock. Ill go check my drag link to see if i can bend it with a little pressure. as far as death wobble, typically out of balance tires, out of round wheels, bad or loose trac bar, and bad tierod ends are the problems. the steering stab has no effect on it and will only mask problems.

pop off that steering stab and see if the shock is bad and binding interanlly causing the steering drag link to bow

I agree, I would think that even in stock form it should be bowing / bending like it is. Is this bar lengthened to compensate for a 3.5" lift kit so the wheels remain straight (due to everything higher would pull the tires and cause a tow in I would think).

If this is true, the lengthened bar would be out of tune to the factory specs causing a week joint in that adjustment section right next to the steering gear box thus resulting in the bow / flex that I am noticing..

Correct?

Its the change in applied force from the joint on the steering box. The increased angle is pushing the bar up instead of out. Not the threads, you need to look at the greaseable joint at the end of the pitman (looks like a tierod end) That is the cause. The result is bar flexing. Depending who did the alighment yes they could have threaded that out to get your alignment right. Thus adding to the result.



Combined with wear, increase of angle, added force of larger tires. Stock replacements should be fine, but eventually it will do the same thing.

When ever i've replaced parts I always do so with something beefier than the origional.

Ah good call on the steering bar.

That would make sense due to the steeper angle of that bar would no longer be a linier force along the bar and would thus begin causing it to bow due to its mechanical advantage over the run of the bar. (The object that comes to mind is a bo-flex machine type setup).

The more this piece of steel is flexed the less rigid it becomes, as a result it looses its strength.

Thus, the only way to really resolve this is to either reinforce it with a stronger beefier bar, or change the angle of attack. Since the latter of the 2 is not possible with out lowering the vehicle I will probably need to replace the stock bar with a heavier one.

Do they make kits that will resolve this issue? or is this something that I will need to fabricate?

If I need to fabricate one, I will either be using tubuliar steel or square stock to help reinforce it.

To me it looks like there are an awful lot of thread showing on the TRE at the pitman arm. This will also cause the weakening of the drag link.

Enigma, the Currie setup that someone posted earlier is probably the best way for you to go. Upgrading steering for most people comes too late in the wheeling experience when they are sitting on a trail trying to sleeve their tie rod with a Hi Lift handle.

Well thats what that currie kit is specificaly for, just and out of the box solution. Personaly I feel brakes and steering a very important safety things and I buy boxed product for anything like that I drive on the road.

If i had the skill to make it myself I may consider it. Then its my fault if something lets loose, other wise I buy something that has some reasearch and devlopment into it.
