Hey Folks,
I have a 2013 LML 3500 single wheel 4wd. A week or so ago, I had the axle seal let go on the rear driver's side hub. Finally got some days off and was able to change it out. I figured since the truck has nearly 200,000 miles on it, I might as well drop in some new bearings and...
Okay so I have noticed on every diesel I have crawled under (including my own) that the parts at the bottom of the block are caked with oil/grease/tar. I have never seen this on gassers. what's up with this?
