Quigley Trac Bar Mount UPGRADE!

[FDM2012]

After 22 years, the Death Wobble finally started on my rig. The center mount bolt was worn pretty bad, and the frame holes that that it went through were waller'd out worse than a ...... (Well, you know)

So, I drilled the holes out to 5/8'', bought a 5'' Grade 8 bolt and drilled it out for greasing the 3/4'' x 5/8'' x 1 3/4'' inner mount sleeve (not shown) that I BootyFabbed. Put in new bushings, and welded a couple of 5/8'' bore x 1/2'' shaft collars to the frame.
So, instead of just the 2 frame pieces only offering a total of 3/8" of pin support,, it now has 1 3/8".

I reckon that will handle things for a while. If not, I will grind it all off, and do it again. It's only metal, right Boy's? #EasyPeezy

Like what you did but I think it is designed so that the inner bushing on the trackbar cannot rotate on the shaft....that is done with the rubber part inside the trackbar ends. To be able to clamp down on the inner bushing hard enough so that it can't move you need a fine thread high grade bolt and the metal parts of the bracket have to be somewhat flexible so that they are able to give and apply enough clamping force..
If you have it clamped tight enough then in won't lubber out your holes either.
Nevertheless your approach is great as well.with the grease zerk the bolt won't rot in place.

I didn't do anything that would change any of your equation. So, if that does apply, I am still in the game.

You are right, I mentioned I think it was designed that way...... We all know that does not mean it works that way.. I personally like what you made and would go a similar route....it was just an observation..
22 years is a long time.. same time as I have mine..
