How can I fix it? I would like to do the work on my own... My dad has a press at his shop, and I have a machine shop next door. Seeing how the gears were in the car already though I don't have instructions on what to do to fix the problem and this would be my first time working on the rear. What would I need to do? I have another rear with stock gears so I can swap that in and pull this one out to work on it...
