Thread pattern on 10 bolt pinion yoke? While swapping my 2.73 rear for a 3.42 rear a bolt snapped off in the pinion yoke. Going to try to drill and tap it but I cant figure out what size tap I need. Any guidance is appreciated!
If you have a left hand drill bit, 1/4" or smaller, you should be able to center punch the broken and with reverse rotation of the drill motor, the reverse drill bit should catch and unscrew it right out. The threads are very long in the yoke so I doubt they are damaged as it currently sits.

That's actually a good thought. I was just dumb and forgot to chase the threads after I had painted the rear end. Didn't think about it at all because it had been sitting for months. Unrelated, but how does your car drive with the 4.56's? I feel like that'd be brutal on the highway through the A4
I work on rear ends and every yoke gets it's threads cleaned from corrosion and gunk before use.
Brutal on the highway, NO, brutal 1st & 2nd gear on the street, YES.
The engine is stock as it's a 'travelling' car and need the reliability of stock. The car's been to Florida from NE Ohio 12 times, 5 of those with the 4.56s'. 2500rpm at 60mph, 3000rpm at 72mph. 3.23 highway mpg is 24.5, 4.56 highway mpg is 21.5, the computer handles the mpgs' very well. Once on the way back on I26 in SC was in cruise control at 4000rpm for about an hour, hooked up with a group of fast moving cars.
