They used a fibre gear for noise limitation, but this came with a significant MTBF limitation as well. If "lose its teeth" means to you the same thing as "completely disintegrates every 60K/Mi" then we're talking the same language. The Ford design was just "OK" - remove the oil pan to remove the front cover to replace the gear. This, coupled with the SAAB design - disassemble the entire car, to remove the engine and transmission to remove the oil pan to remove the front cover to replace the gear,and we're well into the sub-optimal.
