After an E-stop road test yesterday, I found the truck pulls to the driver's side on hard braking. I figured it was no big deal and it was probably just time to adjust the brake shoes, since these trucks are not known for self adjusters working very well.
Today, I pulled off the right rear drum and found a greasy mess inside (pictures to come). I do remember replacing the hub seal years ago but this still seems like a premature failure. If I remember right, it was the unitized 2-piece style seal that has it's own internal running surface. This being the better design, according to what I've read.
I probably don't have time to fix it this weekend but will be shopping for parts for next weekend (probably new shoes and drums too...). I'll inspect further when time permits but in the meantime, does anyone have ideas that could explain a early failure? Do these seals come pre-lubricated? Or is there some other procedure I might have missed when I installed it?
