I've always been a fan of the older E36 body style BMWs so I figured it would be a project car and I bought the tool. It's basically a mechanical press that sits on the axle. Never got around to redoing the interior though and the car may be finding a new owner today. The hardest part of the job was getting the snap rings back in over the new bearings. The cheap Napa snap ring pliers just weren't stout enough. I ran all over town looking for better pliers until I saw the guy in the Mac Tool truck parked a local garage who hooked me up with what I needed.
