'02 V70 XC: Rear diff gears vs Haldex pump vs. What's next?

FWD conversion "until further notice" done. Have put a few hundred miles on it already, seems to be holding fine.

@scot850 you asked me to list what I used to hold the collar sleeve in place. To be clear, I don't think the collar sleeve on this car is going anywhere, but just in case, I did add some bits and pieces. My caliper put the diameter of the shaft at 27mm while I could only find collars at 28mm so I ended up buying these:

https://www.amazon.com/dp/B0CMQMQJ93 (0.5mm brass flashing)
https://www.amazon.com/dp/B0FM3DP5JR (2x 28mm clamps)

Not expensive at all, and looks clean and robust in place. I carefully cut the brass flashing to exact size (took a couple tries) so that I could wrap it around the shaft and increase the diameter by 1mm. I used both clamps rotated 180 degrees from one another, with red loctite on the bolts, both right up against each other and pushed right up against the angle collar. Seems to be holding just fine, I don't see any evidence of movement and I've had it on the highway at 80+ miles per hour for a couple hours.

The restoration of AWD is doing to be a "someday" project as I'm pretty sure the viscous coupler is shot as well. There were a couple instances of "rear wheel ship" when making sharp, tight turns right before the noises began. Not sure which failed first but whichever it was probably helped the other part to fail, so I don't know that there's a point in just doing one piece.

I'll keep my eye out for an angle gear and a rear carrier/coupler, if they turn up, great, and I'll probably rebuild the prop shaft as well as I do it. But I'm not in a super rush... time will tell.
