Installed my 3:73s yesterday

Just wanted to thank Blue70SS for his posts and pictures. Before I started my install I searched and found this thread. It was a great help.

The GM service manual gets you to a step that states:
“Using the appropriate tool, separate the wheel drive shaft from the knuckle. Remove the knuckle assembly”

Knowing that the drive shaft can be pulled out by only removing the toe in strut bolt, the top knuckle bolt and removing the ABS line from the toe in strut was a real time saver.

Also in the GM Service manual it states to NOT re-use the wheel drive shaft nuts, the inner drive shaft washers and the propeller shaft bolts (OK, I couldn’t find any propeller and thinking there was an amphibi car option I missed, I got distracted for a moment ). For us older folks we call it a drive shaft. Not sure why they emphatically state to not reuse them, but I’m no metallurgist. So I ordered them from the dealer, $45 plus tax. I’m betting it’s a bean counter and lawyer driven statement.

I took the diff to J&S Gears in Huntington Bach CA to install the gears and press off the bushings (did the Pfadt bushing too). He only charged me $25 to remove the bushings, but said he’d never do that again

It was interesting too to see all the number on the original pinion gear too.

So thanks again to Blue70SS for the DIY install help.
