    Anyone know why I would get a loud clacking/binding sound in 4 wheel drive? As soon as I get on the gas or turn the wheel, it starts clacking in the drivetrain area. Tried rebuilding the front driveshaft, but that did not solve the problem. Thoughts?

    if you have auto hubs, they might not be unlocked all the way.. try backing up bout 15 feet to disengage them.. mine sounds like a ratchet if i don't back up far enuf.. hope that helps /forums/images/graemlins/cool.gif

    Sounds like it might be time for new front axle u-joints......

    could be the front u-joints, like previously mentioned. but a buddies truck did that, and it was his manual hubs. they weren't locking all the way. the previous owner competely filled them grease. i guess he thought that they would work better. /forums/images/graemlins/rotfl.gif /forums/images/graemlins/rotfl.gif but anyway, check your hubs. /forums/images/graemlins/thumb.gif
