I don't understand why anyone would buy an AWD car and turn it into FWD? (Justin excluded! :rolleyes: ) It's not like they don't make them FWD... Just sounds like a waste of time if your AWD system is working fine.... And if you bought a FWD then you wouldn't have any issue with the rear Nivo suspension either. :blink:

It's not like it's a good AWD system anyway. And it's driven off of the drive axle, there isn't a center diff.

My fuel economy in city is up to 18.4 from 16 and hwy ~25/26 from 22.

If you could pull the rear axles and cut the spline for the rear hubs I bet you could grab another 2/3 mpg.

Car feels quicker. Not a single regret.

No. It's driven off the diff.

Why doesn't the dif then shit a brick when you just drop the ds like on say Subaru/Audi?

I'm not trying to argue. I'd just like to know how it passes as a diff. It still spins with the wheels on the ground regardless of traction. How is that supposed to regulate power being put down?

The older cars use a viscous coupling to regulate power sent to the rear, after ~01 Volvo went to an Active-ON-Demand rear differential. The AOD is controlled by the Differential Electronic Module (DEM) and varies the power sent to the rear via info from the CAN (ECM,BCM,TCM). We now have a newer version but Im really not to sure about it. Anyone please feel free to correct me if Im wrong.

Thanks for the -1!

I would honestly like to know how the angle gear is getting it's power if the passenger side axle is not installed.

There is a small sleeve installed in the trans that is driven off the bevel gear (angle drive, front diff) the rt axle goes through the diff and the sleeve into the trans. The axle is driven by the inside spines of the diff, and the sleeve is on the outside splines of the diff.

So the bevel gear does not contact the axle? You're saying it's getting power from the differential separately?

Yes there is a splined sleeve from the diff to the bevel gear, the axle just goes through the sleeve and the bevel gear.

You can see the sleeve in this pic - the sleeve is attached directly to the diff & the right side axle passes right through without any contact to the BG.

It will only be a problem if you don't rotate your tires....rolleyes.gif

or drive 40 miles with the OEM spare. ;)

I have already replaced it all once...car had about 95K and I am thinking about removing shaft as well...just so I don't have to deal with a 3K expense.

It snows heavy 5 days a year here where I am on Long Island. I drove the E30 all winter long and no issues. No AWD would not really affect things much as I see it.
