Need help again,My 92 W350 is still all over the road at times.I have replaced the steering box,sway bar end links,sway bar bushings,shocks and i have ordered leaf spring bushings.When i bought the truck they had just replaced the steering shaft with a new borg.I have checked the ball joints & they seem ok as well as the u joints on the end of the axles.Please anyone!!!!!!!!!!!! What eles can it be????At times it cant be controlled at all.Its like driving on ice.

 

How are the wheel bearings , alignment, and tires could be separating also try and get the frame checked.

 

If you have a w-350, you don't have ball joints, you have king pins, and they could be bad...Mark

 

Mine is a 4x4.Ive been told i have ball joints.On the moog web page they have ball joints for my truck not king pins.With is it.???

 

A dana 60 has king pins, see here https://www.dieseltruckresource.com/...4-t290373.html . unless it has been changed, it has king pins...Mark
