My 49 had a bad case of the death wobble, as Ryan knows. I knew it was the bell crank bearings causing it. Instead of replacing them with new ones, I decided to try a different approach.
My bearings were not too bad, bit worn enough to have lots of slop.

I got this bearing grade bronze alloy to make my new bushing.

Turning down to size on the lathe.

Boring the hole out.

After is is all set, I drilled a hole in it for the grease.

I put it back together, and wow, the steering is nice and tight. Zero slop now. Hopefully this will last longer than those needle bearings. It should if it gets greased regularly.
