so I managed to get the car back together last weekend, fortunately the engine is smooth and feels strong. I did change the gear oil in the angle gear, the oil i took out did not look that bad, i also repacked the front cv joint on the rear drive shaft, installed a new right side axle shaft, installed the B4 servo cover and flushed the trans. Unfortunately the trans has a slight flair going from 2-3, and also experiencing had P to R and D engagements.....so i may be looking into options for repair/replacing trans. I hope i do not have to buy a new one. I really enjoy driving this car. I am very grateful to volvo xc70.com, a lot of great info here, and helpful people :-D
