[ROVERNET - UK] P6 Rear Axle

Thanks for getting back to me.  The car is a stock 1967 2000 TC.  I have 
not seen the either differential myself, but the owner said that he removed 
the first unit from the car and looked in the inspection port.  He told me 
that both side and pinion gears of the differential are badly damaged.  To 
what degree I am not sure.  The second unit is still in the car and he 
thinks it's the same problem and getting worse by the mile.  I have asked 
him to split the case and evaluate all the parts.  I have never had final 
drive problems other than a few broken axels, and I am about 200 miles from 
the car so I am not sure what is really going on.  I guess the real 
question is, are the differential gears normally a problem?  Any light you 
can put on this problem will be helpful.
