I have discovered that the corner of 1 tooth on my pinion gear has a chip/chunk out. I found the remnants in the bottom of the housing. there is no damage to any other gears. In that I have not yet driven it I don't know if there was any noise or how long it may have been like this.
Finding a replacement, I have been told, it going to be a challenge. Any thoughts on repairing it, or filing the edge and let it be?


the part numbers are as follows;



drive pinion 314961
drive (ring) gear 314958 (confirmed from the gear)
ring and pinion matched set 543276
whole assembly 314841
4.66 ratio

I was able to get the part number from the ring gear and the book gave me the other numbers to go with that gear.

Unfortunately I have the truck on stands to renew all the brakes and too close to the wall to get a slide hammer on one axle to remove it. So until I get the front wheels on and can move it over safely I do not have the diff out.

I appreciate any help and advice.

As has been said elsewhere, grind off the sharp edges. I would ONLY replace the ring and pinion as a matched set.
