Re: clocking dana 300, any lubrication concerns?
With the D300 normally mounted, the main input/output bearings are lubricated through splashing from the turning gears. Clocking the case actually helps the lubrication.
In fact for flat towing (with the tcase in neutral) it gives the output bearing a good chance of getting adequate lubrication since no gears turn, but just the shift collar and shaft.
My d300 is pretty flat and I have driven over 10,000 miles on it without a problem. Some of those miles were full-day drives at freeway speeds.
