I braced the truck with proper wheel chocks, lifted the rear of the
truck off the ground, and started looking. When I would put it in
drive and get to same speeds that caused trouble, I could hear the
same noise. (a fact that I consider good, since I can trouble shoot
I then took off one wheel and one drum. The noise continued.
I then took another wheel and drum. The noise stopped!
The most obvious suspicion, now, is that the brake on the wheel that I
took off last, is somehow not properly working.
Does it make sense?
