After thinking long and hard for at least 10 minutes I reached the conclusion that the adjustment on the diff wasn’t right, and that all of the grit inside of it needed to come out. So I pulled it apart…,
Is the red burned oil?
Same red where the bearing came off.. Perhaps the bearing was running on the shaft. Another reason for my thinking the bearing is running on the shaft is that the shims are razor sharp, as if they’ve been surface ground.
And now I can’t find the blasted seal for this end, I had it, I thought it was in the garage, but I don’t see it there any where. Looked high and low in the shed. I’ll look again tonight.
