One of the problems was gear alignment. They now put a stronger spring in the shifting mechanism. The main gear also had issues. Now, the main gear made from 17-4 stainless. The pinion gear is already made from this harder steel. Just send it in for the fix. It's free.

Mr Bill
17-4PH High Carbon stainless is high dollar stuff... Aircraft Quality metal used for doublers in high stress areas of the wing root and horizontal stabilizer.
Made a lot of repairs on DC-8's and B 727, 737 with 17-4PH and 17-7PH sheet material.. we hand formed annealed and heat treated it.
