Question - AWD diagnostics

tjmotter · Post by **tjmotter** » 01 Feb 2020, 13:28

Working on my nephew's '08 XC90 V8. He mentioned that the AWD didn't work so I crawled under to take a look and do some basic diags. Haldex seemed fine (applied 12V to the pump and it sounds fine), Differential seemed fine but then I grabbed the driveshaft with the vehicle in Park. It spins freely. No noises coming from it and the vehicle works great as a FWD but I expected the driveshaft to be locked. I then used an extended arm camera and had my wife start the vehicle and move it a little in Drive and then Reverse. The driveshaft didn't move.

Safe to assume the Angle gear is shot?

If the propshaft spins by hand when the wheels are on the ground, then the either the sleeve is stripped or worse. Either way; that's going to be a job. The rear end engages electronically when needed.

Well.... The local dealer is happy to fix it. $2082 for labor and $5465 in parts. I guess this XC will spend the rest of its life as a 2WD.

They wouldn't give me a price breakdown on the parts but I know I can get a brand new Bevel gear from the VolvoWebstore for ~$1600 and the coupling that causes the issue is ~$150 so I'm guessing they simply didn't want to do the work.....

You can buy the parts from Tasca or another dealer online and have your local dealer install; that would be covered by the warranty as far as I know? Maybe someone will confirm this?
