Wobble in distributor ???

If you are talking about visible wobble of the distributor CASE this can be caused by a number of things---worn cam gear, worn slot in the dist. drive, bad block bushing, etc

It can be caused by wearing of the slot and tang of the dist. drive, on, the other, both

Bent dist. shaft, worn dist. bushings.

I'm afraid that, compared to other drive systems, the Mopar is somewhat deficient. GM has much better support for the dist drive, and even Ferds have a "pilot" shaft of sorts below the cam gear.

What would really improve Mopars would be either a better coupling (not the slot/ tang) for the dist, or even to make the entire distributor and intermediate shaft all one piece.

Of course now we have crank triggers......
