i used to use a breaker bar and crank on them till i started noticing this prob ( i dont get to do a lot of high speed driving ) and its been really crappy this week so far and its not looking better in the forecast for the rest of the week so i prob wont get to drive it for a while but i tried rotating the drive shaft again and rotated the wheels again what are some of the causes of this type of problem that i may have overlooked any one else out there with any guesses
