<VV> 65 CorvairPG pinion gear.

[james davis]

Extreemely common on UltraVans and FCs.  I had three spun pinions in my 
UltraVan over 188,000 miles.  The current theory is that forced 
downshifts at full throttle is the primary cause.  Of this is only one 
explanition.  Walt Davison was of the opinion that the pinion gear and 
shaft were married at the factory and do not take kindly to divorce.  I 
have spun two pinions in my Rampside over the last 35 years.  Both were 
where the pinion was swapped onto different a shaft.  My Rampside works 
for a living often flat towing other Corvairs or hauling a 3,000 lb 
loaded trailer.

I was slowing down to a stop in my 65 4 door when I heard a high pitched sound. when I stepped on the gas to go it would not move. I've started removing the engine to replace the differential but want to be sure I'm changing the right thing. Jerry Brown
