Well, that wopld be odd, cause I too have a problem with my drivetrain over
55. The thing is its 4wd and I just replaced all of the U-Joints this week
along witha complete diff service. Shafts were check for balance as well.
and new input output shaft seals at both ends of transfer, along with a great
break job, my brakes are so excellent...
