rear wheel bearing

[Calmg0d]

Excellent thread going here. Just this past weekend I replaced all four struts, lower control arms and the things that go from strut to front sway bar. Anyway, I thought that would fix the insane grinding sound I get when aggressively taking corners. It didn't. After I took it to get aligned today the guy at my alignment shop said that the thumping noise I was getting was caused by a bad left rear bearing. So I figured I could replace it. I have access to a shop with practically every piece of mechanical kit and lifts known. My son and I did the change in 8 hours but we were beat.

Finally, my question. How technical is the bearing pull/replacement? I have decided to park the 2000S until I get the bearings in because the thumping of the left rear is only getting louder and more distressing.

Will I be able to accomplish the pull/replacement in 7 hours for both rear bearings?
Thanks for any and all info.
