Have you checked the transmission mounts? also, you might want to check the bearing for the output shaft on the back of trans?

Vabration


IS that vibration related to RPM? If so the harmonic balancer and or the crank shaft might be out of balance. If it is not related to RPM, then you need to check to see if the shafts are all installed correctly and the motor mounts are ok. It could also be the tires flat spotted if they sat a long time.

You will need to check things logically. Run the truck in the air and note where the vibration is at. Take the wheels OFF and put a few lug nuts to hold the rotors on, take the truck to 45mph or whatever the vibration is the worst. is it still there? if its gone, check wheels/ tires. if its still there, check rotors, axles. A drive shaft will make a rapid vibration at low speeds since it turns 3 to 4 times faster than the wheels. does it vibrate on or off the gas? Can you power through the vibration like go 60 and then coast back through? You have replaced a lot of parts that would not cause vibrations. Are you just changing parts willy nilly or is someone actually checking and verifying that these parts really bad?
