AWD not working. Need help troubleshooting.

[JRL]

AWD system does not show failure messages in a display code-
You can see a DEM module or pressure sensor failures only thru VIDA at a Volvo dealer or if you have a VIDA-DICE set up

I can't wait to dig into this problem with the support I get here.
Thanks again...

Ok guy's, here is the update. I lifted the car and ran it in drive. No driveshaft spin! I have good mechanical skills and above average tools. Any tips or tricks before I dig in?
Hey, Thank you! Absolutely appreciated.....

if driveshaft = propeller shaft
then no AWD

Take down the propeller-shaft for next step. see Resources for pertinent how-to.
Also read Howard's take on this.
Please do not take shortcuts and/or rush if you are taking it on.
SAFETY FIRST. You can do it with fewer F words.

I will be carefull. Will anything leak out with the removal of the prop shaft?

Any idea what this repair would cost at a dealer??

[JRL]

Broken collar gear only?
$120 or so for the gear, probably 4-5 hours labor

It took myself and a friend about 9 hours, but I took my time and also replaced the front L&R axles.
I used the method of pulling the collar off using a 3-arm puller that I rented at local auto store and cut slots (angle grinder) into the sleeve so the puller would have a good purchase.
There is also a home-made device consisting of a large (cannot remember size) socket, some washers, and a bolt, whereby it rested on the inside spline (trans side) to provide an anchor for the puller.
This method went smoothly and because there were no impact tools used on removing the sleeve, I did not induce damage to the transmission or drivetrain.
The parts are dealer only... I purchased my sleeve and M02 grease from Tasca. I also used phenolic sealer to keep water/crud out of the sleeve portion of the housing which is not isolated from the elements and used a large amount of M02 grease hoping it wasn't going to rust itself together with the spline again.... we'll see!

There's a good write up on Swedespeed, which covers the entire procedure.

Maybe a little 75W90 will come out. More importantly, make sure you somehow keep track or label exactly which bolts came from which bolt hole and that everything goes back in exactly the same order.
