Transmission questions

[Peter Golledge]

Both the diffs and the gearbox are quite sturdy.  About the only way to kill
one quickly is to Auto-X with the center diff locked and 400ft/lb of torque
coming in from the motor. :-)

It must be a sturdy differential!

.... I believe they are referring to the gear ratios inside the
transmission,
but you are correct that having unequal FDRs in the diffs can cause
excessive differentiation in the center diff, which may cause excessive
wear.  

I owned a 5000 TQ which had different ratios in the front and rear diff ....
I didn't figure that out before buying the car ... I don't know how long the
car had this configuration, but it didn't show any signs of center diff
wear.

Wouldn't that tear up the front to rear
differential?
