I'm shopping for a used AWD CRV.

I wondered if anybody on the group(s) knows if there's a simple way to
tell if the rear differential on a CRV can be tested (in shop, no
roadtest).

My theory (which I never tried on our last CRV):

Engine stopped, tranny in gear, (or park for an auto) lift one rear
wheel off the floor. I figure you should be able to rotate that wheel
forward or backward slowly, with a fair bit of felt resistance. If it
was really cold outside, the resistance would be greater because the
'Dual Pump Fluid' would be stickier in the differential's clutches.

Anybody read a procedure like this in a service manual?

P.S. I realize this is a very narrow test of what the differential does,
and wouldn't spot other (possibly expensive) problems.

What do you think ? ? ?
