We discovered that the rear diff in my son's '85 was shot (a lot of metal chunks and next to no teeth), so we're getting ready to order some parts for it to have it rebuilt and I have a few questions.
Does this look normal on the ring gear case? I'm not sure if it was damaged or if it was manufactured that way. Do you think it sould be replaced?
Here's a pic of the pinion gear.
Thanks.
