[urq] DAMMIT! Center diff casing failure

[james accordino]

On my 89 200q, the output bearing failed.  Wiped out
the seal and fluid dumped all over.  Replaced the
bearing and the next bearing in along with the seal.
Refilled with fluid and is all good for 20k miles so
far.  Something to explore when looking for a cause.
Seems to me that the output bearing on the center
diff. and the input bearing on the rear diff. take
alot of stress and should be checked/replaced after
say 150-200k miles.
