Knocking noise when turning.

[Uppie89]

Well I havent messed with the suspension on my Super Duty yet. When I turn the wheel there is a clunking or knocking noise from the front end. Only when I turn. Ball joints, Universal joing, tie rods. Any way to check?

thanks

well they can clunk when your hubs are locked in causing the axle joint to turn and clunking, usually when they clunk when turining(and moving) indicates a bad joint. you can look at the joints looking for rust or if they are loose. or you can pick the front end of the truck off the ground lock one hub turn the wheels all the way to the left or right and then try to turn the wheel that has the hub locked if it doesn't want to turn this means the joint is froozen on that side. I hope this helps

I also have a popping clunk. Looked under the truck today saw on both sides the seal behind the ujoint is free and sitting on the axle. not to sure what this is called or what to do??

I had a clunking on mine and found that the sway bar bracket bolts that hold it to the frame were loose.

well that is a "dust" seal and keeps all the dirt and debris out of the axle tubes. This is pretty common they just get old and rot.

So on the left i cant see in the tube. On the right i can! what should i do with these "dust" seals how do i get them back in thay are not torn or have any rot??

well you have to pull your axle shafts out and get the new inner seals from the ford dealer. if you do that you want to check out the axle joints really well and make sure all your vaccuum seals are okay for your automatic locking hubs. (have you checked your axles joints while they are in the vehicle yet?) If you have any questions or need further assistance or something to be cleared up let me know

Had the same thing as cubalz but my bracket was broken, replace it and problem was gone

Same issue with the noise all mine turned out to be was the leaf spring bushing, I have heard the same issues being the sway bar bushings. Easy way to tell is spray the bushing with a lubricant one at a time and test drive when you have found the culperate the noise will significantly lessen or go away entirely. Good Luck.
