Direct drive, not fluid coupling V70-XC70

posted by  someone claiming to be Frank on  Thu Dec 25 04:18 CST 2003 [RELATED]

There is NO fluid coupling to the rear wheels at the front of the car, it's strictly mechanical and done via a simple bevel gear (like a ring and pinion inside). Like any differential (and FWD/AWDs are inside the auto trans), if one wheels drive axle is disconnected for any reason, the other side also won't move.
To make it RWD, it'd need a different AT w/o a differential inside BUT with an angle type gear setup to direct the power flow to the RF axle where the AWD bevel gear is attached. A trans like that doesn't exist by Volvo. The weak bevel gear (hot topic here) and rear viscous coupler (a semi fluid coupling device to control slipage in front of the rear diff) couldn't take full drive power w/o blowing.
