Pre-2001 Volvo XC70 AWD Drive Shaft Removal
From reading this and other forums, lots of people are running former AWD cars w/o the driveshaft. The actual driveshaft unbolts from the angle gear and the viscous coupling at two flexible couplings. Here is a picture of mine at the rear. The front coupling is identical.
1. Remove two bolts from center exhaust hanger that hold the center bearing support in place. You may have to loosen (or remove) the support itself from the body, four bolts.
2. Remove six 6mm allen-head cap screws from the front and rear “flanges” of the drive shaft.
3. Sharp raps on the rear flange (the rusty part in the image previous to this post) until the rear of the shaft falls free.
4. Remove shaft to the rear of the vehicle.
