        Stopped the squeak/leak

        Great product. Replaced because it was leaking/squeaking on both sides. Easy install with their videos, had no problems over 6 months later. Need a slide hammer to make it easier.

        These are great!

        Well, got a new differential put in along with all new bearings, seals and shims, and these seem to be holding up just fine, so I'm happy.

        Why Not?

        Had this done while installing new 3.73 gears. Even tho my 2010 is low mileage, about 45,000 miles, it just seemed to make sense to do it all. Preventative maintenance is always a good thing.
