RE: Backdraft 8E strange deal???? HELP!
Check to make sure your front drive shaft coming from your center diff to your front diff is not bent. If it is bent bad enough which unfortunately can be straight out of the box. It will cause you ackerman plate inbetween your servo saver posts to bounce that bounce will cause your steering knuckle to bounce.
Also check your dog bones going to the wheels for bends.
And like stated before check your front differential.
