[Healeys] Rear Axle issues

[David Nock]

There is was to look at this. The most common cause is the shims  
between the pinion bearings go bad causing some movement in the  
pinion bearings.

The only correct way to fix this is to remove the third member and  
replace the damaged shims and adjust the preload on the pinion  
bearing. Then you can install a new seal.

The other option is to simply remove the drive flange while in the  
car. You can then replace the seal re install the flange and you are  
done. The problem with doing this is if the adjusting shims are bad  
and you re torque the pinion to the original specs. You will have  
changed the pre load on the pinion bearings and they may go bad.

Either way be sure and clean up a sealing surface on the pinion  
flange with some fine emery prior to installing the flange. If there  
is a bad wear spot on the flange you also can install a redisleeve  
which will put a fresh sealing surface on the flange for the seal to  
run on.
