Kenneth and Roy spend New Year's Weekend getting the ARB locker mounted on the Dana 80, and work their way through the axle install steps through running their first pattern. They don't quite finish the work, but there's only so much that can get done in a weekend. April is away at a United Kennel Club show with Zephyr, so apologies in advance for the camera work. It's indeed difficult to work and film at the same time. And also apologies for the background hum. Winter in Colorado means the propane furnace was on in the shop. No, no apologies--the boys refuse to be cold! Editor's Note: This was thought to be a 2 parter, but it turned out our memory was stale. We forgot that there was a parts order that stopped our work, and the next video will be the front Dana 60, as we await parts.
