___ CRV differential diagnosis question:

    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 ? ? ?

    The correct technique (from the manual) requires all wheels of the
    ground, put it in gear. All wheels must be spinning. Then set the
    parking brake. In auto trans. vehicle all wheels must stop, in manual
    trans. - the vehicle must stall.

    HTH,
    Dmitry.
