Does anyone out there know of a source to buy the locking washer that fits between the two nuts that hold the drum/hub to the axle tube? Also I have a recurring problem with the e-brake cables rusting/freezing up. I have replaced these twice in the last two years. Is there a mfg. of cables that work like the originals did? Any help to these problems would be greatly appreciated. the axle I am asking about is the Spicer 70 model with 3x12 brakes.
