Re: Rear brake problem
I'm surprised no one had the same issue but I figured it out so now i have something to contribute to help others.
If you feel a vibration while driving on the highway, about 60 mph, and you determine it's not your U-joints, a tire/wheel issue, loose bearing, or a bad suspension part look at your rear brakes. The rear, drum style, brakes on my XLT were "loose". The reason they were loose, the self adjustment mechanism was not working properly. Actually it was so loose I could take it off with out removing it the way the manual instructs.
Since I had to replace the passenger side self adjuster I spent the extra $20 and did the driver side and also replaced ALL the springs in the both rear drum sets.
The truck stops like a dream now and doesn't shake on the highway. I surmised the rear passenger side shoe were dragging on the drum, heating up and then acting like an anti-lock brake system pulsing on and off generating the shaking at high speed.
I'll post a few pics later.
