I decided to finally tackle the swap of the rear subframe and gas tank on the Volvo. The original rear end to the silver car has a center differential that is caked with grease, it appears that the halfshaft seals are leaking.

At about 7 hour in to get to the point of having the replacement rear subframe bolted into place.

At about 10 hours to have the car back together. I now have the good rear installed with 2000 V70R vented rear brakes with SS braided lines. I also got the IPD rear sway bar swapped onto this rear. All I have left is to replace the cv joints on the driveshaft and I will have AWD again.
