87 300TD rear wheel Bearing (Help!)

Deep dark depression, excessive misery! If it weren't for bad luck, I'd have no luck at all!

I was about to leave work this afternoon (sick as a dog) when my wife calls and says the wagon is making strange noise in the back, especially while braking and going around corners.

I took it for a drive and there was definitely some noise back there, mostly when turning to the right. I was kind of a clunking noise, not unlike what you would hear from a bad CV joint on a front wheel car, but not quite as severe. Into the garage and onto the jacks (after I applied all of my own safety advice), and here is what I found. Drive shafts and center bearing, flex palte all look ok. Right wheel has a lot off slop (wheel bearing type of slop), left wheel is OK. No noises turning manually. I really think it is a bad wheel bearing, especially after removing the whell to shake the hardware up close and personal.

I popped in my handy dandy CD and did my research and see all kinds of pullers and presses are neede if parts are stuck. Obviously, I don't have all these, but I am a pretty good jury rigger at times. I have also replaced pressed in wheel bearings on front wheel drive cars many times, when I had access to a hydraulic press.

Will I really need to use all these tools or should I just cut my time losses, tuck my tail and bring it directly to the shop? I am willing to buy the axle nut socket and half shaft bolt (what is the size, # of splines for this?).

I probably need to start tomorrow, so any words of wisdom my "Shop" buddies can give me would be appreciated. In the mean time my wife is driving my baby (Suzanne, '72 280 SEL 4.5) which is more than enough incentive to get this fixed ASAP!
