<VV> Bad Noises!!

[JVHRoberts at aol.com]

The posi diffs are notorious for having the side cover, the one with the 
clutches, break around the clutch pack, and now the ring gear will wobble a bit 
inside. It does sound like this is what may have happened. 
This part is weak by design. The non posi diffs don't have this problem. 
Otto's, or someone, used to make and maybe someone stiff does, a billet steel side 
cover for the posi diffs that fixes this problem.

I'm calling on the differential experts for a little remote trouble
shooting.  While happily driving my '66 Turbovert, I noticed some weird
noises coming from the rear end (I think).  I was parked and when I tried to
back up, there were a couple of loud bang-clank sounds accompanied by a
kinda lurch or jerk.  I pulled back into the parking place and took a quick
peek under the back, checking half-shafts etc.  Everything looked ok.  I
decided to try driving home, nothing unusual occurred, engine good, trans
good and no more weirdness.  As I pulled into our driveway, I had a bit of
coast and then power, in other words a bit of slack followed by power and
there was another clang and you could feel a kind of "hit".  I feels sort of
like something is stripped, slips and then catches again.  I'll do a more
complete look-see tomorrow in daylight. Any ideas?

Thanks in Advance.
