Approximately 4,500 miles ago I installed an entirely rebuilt 3:73 Posi
diff in my 62' Corvette. The frist problem was a pinion seal that started
a very slight leak at about 1,000 miles while I was on a trip. It was
replaced at about 4,200 miles when I got back from Spearfish! The Red Line
75w-90 had a ton of very small flecks of metal in it, which I found upon
replacing the seal. I immediately changed it (both times adding the GM
Posi Lube) and now some 400 miles later I have more flecks of metal. No
sounds or other discernible problems with Posi or diff at this point. I
also replaced the axles and axle bearings when I put in the "new" Posi diff.
Questions:
(1) What is the most probable source of metal flecks?
(2) If this a self-correcting problem short of failure? (Yah I know, but I
had to ask!) If not what is the correction?
(3) If I continue to drive it, what is the likely outcome?
Thanks in advance...
