Few chipped teeth on the side gear (left side) Didn't find any chunks in the bottom of the pumpkin apart from some small flakes or damage on any other gears so it looks like the damaged may have happened with the previous owner?? I''ll put some heavier oil in and keep an eye on it over the next few months while I look at replacing it with an auto or lunchbox locker

So I guess the question is which auto or lunchbox lockers are worth putting in?

I've had a powertrax no-slip in my Jeep for 180K miles or so. No problems but needs a spring kit for a whopping $17 from Summit racing. And I still have the spiders from OEM if yer interested.
