All,

I'm days away from getting this car finally on the road (2007, XC70, 198k miles), and after cleaning all the rust off of all the brake rotors I decided to check and see if the rear wheels spin as I'm starting to believe PO had zero experience with an AWD car.

Sure enough I started the car, E-brake off and I slid the car into R and stepped out of the car. Front wheels move but rear wheels do not.

I do the same with D, and I get the same result.

Can you say CRAP!!!!!

Wasn't planning on changing the Haldex or rear differential fluid just yet, but it looks like I'm going to now.

Any ideas as to where I should start in diagnosing the problem?

Additional information is that the info screen tells me that "Anti skid service required", not sure if this is related or not. I'm so new to this car that I have no idea, but will dig in to fix this, cause that's how I roll.

Thanks in advance,

Matt
