Dodge 3500 steering

Some of the responses above make me think it was a good idea to install a steering box brace, O those many years ago. I has a BIG, zirked, capture bushing (not bearing) surrounding the output shaft (right where you need it) connected to a sturdy cross member than keeps the left front frame horn from contorting, something it did at will before the brace. I noticed an 80% improvement while driving in the right lane down the interstate (with those pesky truck tire trenches) and most of the wander disappeared. Most. I must still respond to some surfaces. I never did have the death wobble (unlike a couple old jeeps i've owned). A simple steering stabilizer is, for the most part, window dressing. I took the factory one off years ago. They just mask a much bigger problem. I want to know about that problem, unmasked. I have toyed with:
Caster, + and - mostly with wedge shaped shims
Camber, mostly due to bent axle housings.
Toe in, usually get the wobble with not enough toe in.
wrong tire pressure. played with this a lot.
The things to remember are that the factory installs parts that are:
1. easy for the factory to install. That's why so many parts are in unitized, unserviceable multi parted chunks, and when it goes you must replace the whole thing.
2. require little or no user maintenance. That's why no zirks. When an unserviceable front end part looses its lube, it must be replaced.
regards, as always, jefe
