Well started the truck up tonight at the local bar and went to push the brake pedal and all I felt was a "shimmy" in the brake pedal. Never felt it before and thought it was weird, anyways pulled out of the parking lot and started driving down the road and everything felt great so I didnt think much of it. Hit a light and come to a COMPLETE stop in drive and can feel it again. Put it in park and can still feel it there too. Its mostly in the pedal but can be felt in your behind too. Go pedal and its gone. After about 10 minutes of driving its gone and cant get it to happen again. Anyone have this? Converter? Injector?

 

If it only does it as you slow to a stop it's probably a u-joint. I just had that problem with my 03. I think I might have another one going bad too.

 

its not when coming to a slow stop. Its COMPLETELY stopped. I can put the truck in park, let my foot of the brake, and when I touch my foot on the brake pedal again I can feel it. Like the whole drivetrain is vibrating. Pedal kinda feels like ABS kicking on but very lightly. only at idle.
