why does my ford f250 jump when in four wheel drive
when i make a turn the truck ack like it wants to lock up i have check the lock in hubs they seem ok what would be the problem
check your outer universal joints on front axles near hub see if they are seized up and also jack up truck on axle check to see if you have bad ball joints loose or seized ball joints
The truck jumps because there is no differential action between the two axles. There is no problem. The 4x4 system on your (and most) truck is designed for use on slippery surfaces. Using it on dry pavement, where traction is good, will cause the drivetrain to bind. Normal Operation.
