Really need some help. I have developed a shudder while driving my truck. If I put it in neutral and coast, the shudder follows me down to a stop. I had it up on jacks and couldnt find anything wrong with the drive shafts or carrier bearing. It seems in may be in the front end mostley. I do have a little play in the ball joints but nothing excessive. Engine runs fine with no codes recorded. With the windows down I can hear a high pitched chatter as tho a gear was rubbing something and the shudder gets worse as I slow help. Any thoughts. Would a wheel bearing in the front end be causing this? Thanks again for any help. Moe
