This is what a proper diff looks like that tows, hauls, exposed to salt water with a steel finned factory cover, with no leaks, no adding amzoil to eliminate chatter, no after market non sense, no bs having to inspect gears and that non sense, no maintenance after 6.5years and 155k miles. As a matter of fact I used the Electronic Locking Diff (ELD)Lock this morning while getting out of the deer camp while pouring down rain.
