[NoVa-Corvairs] The honeymoon is over

[Curtis L Shimp]

Daniel:

If you find no other apparent cause for the noise and plan to replace the
part suggested on Virtual Vairs it would be the differential not the
transmission.  I have never torn and rebuilt a differential.  In the past
it was always easier to get a replacement diff.  I think that you need
special tolls and equipment such as a shop press to replace a pinion
gear.  However, as parts get harder to find you may have to get someone
to rebuild yours - maybe The Corvair Ranch.  The last time I wanted work
done on a diff I shipped to Larry Claypool.
