Price a new S60 bare housing and compare against the core + labor.

Also give some thought about whether you care about the lack of snubber provisions and very slightly greater complexity of service (compared to an S60 with diff bearing adjusters) on truck housings.

I'd done that a few years ago and at the time I think there was a small savings going with a salvage yard piece, but it
may have been worth it to pay lightly extra and not have to do any of the work, and have a shiny housing with no grease or rust to deal with, nothing to cut, just build it.
