does anyone know where i can purchase the hub?
check your local salvage yards.
if you have automatic hubs your best bet is to change to the manual lock outs... i had my automatic hubs go bad on me and the only place i could get a new one was from ford and they were 400 per side. so i spent the 300 dollars and did the manual hub conversion and they work extremely great and are extremely reliable.
