Re: Bentley Chassis B-145-GP - Rear Axle Pinion GB.2351 - Mileage 14,216. I am forwarding to you a GB.2351 pinion taken out of a noisy axle. The case hardening of the shaft has sunk and is badly pitted. It would appear to be due to the depth of the hardening not being sufficient. This is the first case we have had of this complaint.
