Trucking in the Northland

Well this last trip was interesting and I had a first for me. Climbing up a steep hill in low gear and something just seemed off. I couldn't quite place it, but my gut told me something wasn't right. Got to the top o the hill and crawled all over under the truck and couldn't quite place it. Got back on the road and I watched my rear drive axle move in the mirror when I shifted. Bingo! Thats what was wrong! I was seeing more rim in the mirror than what I normally see. Took it real easy an finished out the trip keeping a eye on the axle to make sure it wasn't moving more, and I also put chains on it front and back to limit how much it could move. Got it back to the shop and it has a broken center pin so it will be down for a couple of days.
