Wow, another ex Bell Telephone truck ( special order green paint). These C 20 No Spins have a problem of "racheting up" on left turns. Eventually they wipe out pinion bearings and your rear end howls going down the road. No problem, at 250K when this happened to me, I junked the 4.57 No Spin it and replaced it with a 4.10 standard differential, quiet again.
