Recently had the front drive shaft replaced. After a few weeks, the truck started to ride louder and vibration at around 35mph. Once the car reaches above that it subsides. Seems to be shifting normally. Having the guys that did the repair take a look tomorrow. Just wanted to get some thoughts prior to seeing him.
