Having problems with your 2002 GMC Sierra ?
Vibration at 40mph to 45mph, smooth up to and after
Do you have a clunk sound from the drive shaft? either way you may have a bad u-joint or it is a tire balance issue. but tires usually have issue's around 55 to 65 and u joints are more in the 40's . so have the u-joints checked out because this is the most likely cause. let me know if you have any more question and good luck
