My steering box

[Terry,NJ]

My latest project is that my Coupe's steering box is kaput. It's "Death wobbling" all over, even on smooth road surfaces. So I got it out and dissasembled. Many worn parts, many questions! There's no doubt that the sector shaft, bearings, and the worm must be replaced. But what about the large race? It looks good but looks can be deceiving. Any one have any thoughts or suggestions? This is my first one!
