need help on noise in front-end? Sounds like a u-joint,but all joints are good. If it is pig in front-end where can I get a used one. 85 F-250 4-wheel.
What kind of noise? When in 4x4 some front end noise is normal, especially at street speeds. A low pitched whine is normal and I wouldn't worry about it. Just make sure your differential and transfer case have the right level of fluid. If the noise doesn't go away when in 2WD with the hubs unlocked, check your bearings.
