Did notice some whine on the drive home, one of the things on the 'to do' list, so its a good possibility its coming from the front axle? Is there a way to confirm what axle this is? One comment posted Dana 60, & another Dana 44.....You got to wonder why in 52 years there were no locking hubs? The rear has a leaky wheel cylinder and the seller made a comment about not being able to get parts for Eaton rears? I don't think brake parts would be an issue???? I will say this, I made a mistake replacing the front wheel cylinders on my 70 C 30 with Chinese junk, when I got all done, I wasn't able to bleed the brakes with a wrench, as the bleeder was against the brake hose. I had to use a needle nose vice grip to get it done....Moving forward I will bead blast the cylinders, paint, & rebuild them....
