We just replaced a howling rear diff on an 04 xc70. Now after getting rid of all the network issues (here's that: http://www.volvoxc.com/forums/showth...-s-how-it-went )
We are at a loss as to when and how haldex works. When we got the car and found the issue on jack stands, all 4 wheels turned.
Now only the fronts spin. On dirt and pavement, in the air, only front wheels turn.
I took my car out, and same thing 2 wheel peel. Mine has not been worked on, and they both have no messages on the dash other than SRS.
Ugh, someone explain the ins and outs on haldex?
How do I know if and when the AWD works???
