First time driving it since the D60 install. D60 was rebuilt with everything new, cept the rotors. I didn't turn them either (resurface). So when I'm driving with any speed of 20mph or more, and step on the brakes I get a good amount of vibes on the whole truck. I'm hoping its just the rotors needing to be resurfaced. When the D44 was still in I had no vibes at all when braking.
