After pulling off the diff cover on my DANA 35 (open diff, everything's stock) I saw this. It seems like a few teeth on the spider gears are chipped. How bad is it? Anyone know what it would cost at a differential shop to have this taken care of? Is it okay to drive like this for a little bit? The weird part is, I don't hear any weird clunks or anything, just a slight whining sound.
