I'm trying to replace a bad u-joint in a motor home build on a Ford E0350 Superduty chassis. It has the star/spline type bolts holding the driveshaft to the differential. Picked up a a set of metric and a set of SAE sockets figuring one would fit. None do. It's around 1/2 in. Is there s special socket for this or are they just rusted small?
Thanks, nothermark
