if I thought an R a few months ago. I was having a little fun the other night and the front wheels broke loose. I shut the traction control off and the front wheels will just spin. any ideas? coupler, angle gear, haldex.. is there anyway to diagnose what broke?

Probably the collar sleeve... Is there any fluid coming out of the angle gear? If it was Haldex, you'd probably have an error message.

Drive carefully or your front tires will be worn to threads in a week.

No error codes. And no leaking that I've noticed.

you can try thins: jack up one side of the car so you can turn a front wheel and still see the center prop shaft (use stands of course)! If the sleeve is stripped you will be able to turn the front wheel and the prop shaft will not turn. If the sleeve is intact then the prop shaft will spin with the wheel.

If you scan the car, most of the rear end failures will show up in the DEM fault code list- pump failures, DEM failures etc.

For my part- I had a bad pump motor most likely caused by the clogged haldex filter with "lifetime" fluid...

Would Those failures cause a cel? Or would I have to scan to see the dtc

No CEL/warning light- you would have to scan to get the code.

Yep, if the DEM detects the oil pressure in the Haldex unit is too low it throws a code but no message at all on the dash.
There's probably a lot of AWD Volvos running in FWD mode with clueless owners...

What type of scanning would I need to use to detect it

If that coller is stripped, no codes will pop up. The center drive shaft always spins with the front tires. If its not spinning your sleeve is dead. Simple as that.

I'll check the shaft before I do anything. Might need to track down a scanner. I'm used to vagwith all my vws.. the R is my first Volvo

'04r... my money is on a stripped collar/sleeve. +1000000 if it's never been replaced before.

Hasn't been replaced as far as I know. Car was owned by an older guy and maintained regularly at the dealership.. only has 80k mi. Really hoping its something simpler and not as expensive. My luck its probably the worst case. I'll know in a couple hours when I check the shaft spin.

So I jacked up one side of the car. Spun the front wheel freely.. car was in neutral and the rear wheel was still on the ground. Does one entire side have to be off the ground or just the front wheel? Also, car doesn't need to be in gear for this.. correct?

If you had three on the ground with only one frt wheel lifted when you were able to spin then it is the collar.
Does not have to be in gear.
