1932 - The Tie Rod Wobble

[uncle buck]

The 36 shaft is hardened for use with the needle bearings. A non hardened shaft will quickly be grooved by the high contact stresses. You need to watch it.

I guess time will tell then. It is also a reproduction sector shaft so who knows, it may or may not be hardened.

If your running dropped axle, big n little tires it would also seem logical that you also changed to 39/40 hydraulic brakes and probably changed to the later spindles as well. If you did change the spindles did you adjust the steering arms to account for the Ackerman Principle? It effects steering and may contribute to front end wobble. Just a thought.

I think you will find placing a steering damper on your tie rod is a pretty popular fix for this situation. The VW damper is also popular and if your parts house can’t supply you might try Amazon.

Can you provide the part number? awesome idea.

I completely redid the suspension on my 32 Cab -- dropped the 32 axle a couple inches (still running a wishbone), new spring, new shackles, original 32 spindles, precisely honed kingpin bushings, original steering (only has 6,000 miles on it), stock drag-link, stock tie-rod, etc.. I have big-n-littles . . . and have never experienced any sort of death wobble.

Maybe I'm lucky, or maybe I just have a well sorted out suspension - who knows.

find and fix the problem its somewhere in the front setup fitting a damper will only hide the cause and is not the cure as stated the first place i would look is the caster followed by kingpins etc also lhand /rhand must be the same otherwise they fight each other [ie 3deg castor on rhand means 3 deg castor on lhand] the only time i personaly would fit a damper is extreme rough dirt roads and then only to try to control/reduce bumpshock back thru the steering get someone that knows what their doing with beam axles [heavy truck] as you may actualy need to bend/twist the axle to get it correct

Control feedback is generally caused by a dynamic wheel/tire problem and then exacerbated by any looseness in the control system or suspension. Most items have been covered.

If a person could watch how the reproduction tires we purchase are made, it becomes evident that the tires can end up with problems just like a core shift when casting an engine block. Most problems are evident when the carcass is inspected coming out of the mold but not always plus road hazards are not always something we worry about after hitting debris or a bad pot hole. We tend to take our tires for granted.

Helicopters can get control system feedback during take off or landing. It's called ground resonance and it's very destructive if the operator doesn't quickly correct for it. It's caused by either a rotor imbalance or a tracking imbalance that affects the phase of the blades. Like an automobile steering system, the rotor control system feedback is exacerbated by any looseness in the system or the landing gear that supports the machine as it's taking off or landing.
