DrB, I'm actually in the middle of doing that right now (it's a FWD V70, which means all but two of the rear suspension bushings are the same as on the AWD/R models). I've been pressing out the bushings using a combination of a 20-ton hydraulic press from Harbor Freight, and a ball joint kit from Amazon. So far I've got all the bushings out of both spindles, and while the HF press is great, the weird contours of the spindles are such that I've been primarily using the ball joint kit (hard to get always get the proper clearance for the press arm).
Subframe DEFINITELY has to be dropped if you want to replace the upper control arm bushings; dropping the subframe will also make it much easier to remove the front toe control arm bushings. It's been pretty slow going for me on this project, but that's mainly because I've only been able to squeeze in an hour or two a couple nights a week after work. Right now, I'm trying to find a local machine shop that will make some delrin bushings for the three upper control arm attachment points, and the inner LCA bushing, as well (since there's no poly version available for FWD vehicles). My concern is that, with all other positions replaced with poly, OEM UCA bushings (even if freshly installed) won't hold up very well (and given that the front UCA bushings on both sides of my car were totally thrashed, I'm suspecting that these positions do seem a fair amount of stress).
Biggest surprise so far; while taking apart the passenger side, I found that the bushings/arms were under virtually NO preload, whereas the driver side was clearly under tension. I'm thinking that this (along with the thrashed bushings) is *hopefully* the source of my weird, passenger-side sidehop-type issue. Will see once we get it all buttoned up and back on the road.
