So I have the snout here and I'm supposed to drive the shaft to the rear with a plasic hammer. I have a 3 lb plastic sledge here and I've got both hands driving and this thing WILL NOT move. I have to be doing something wrong, I feel like im gonna crack the housing.

I don't know WTH you got that advice from but you'll need to press the shaft out and you'll need a press to R&R the rear bearing as well. You can't do this job without a press.

"Now you can start disassembling the snout by first removing the retaining clip on the front end of the snout that holds the seal in. Using your rubber mallet or soft hammer, tap out the shaft from the front end of the snout. The shaft should come out fairly easily and will have one bearing still on it. There's a spring in there that will come out with the shaft also."

"Disassemble the Snout: - using a rubber mallet, tap the front of the snout shaft to knock the shaft out the bottom of the housing. It will come out with the rear coupler, rear bearing and a spring all as part of the unit."

"Remove the shaft. (Use a plastic hammer to drive the shaft to the rear of the snout. The front bearing will stay in the snout.) "

The circlip & seal being out should at least let you see better what you're dealing with, in terms of damage or signs that the snout was maybe cooked and perhaps more prone to hanging on to the bearing. The rebuild tips usually mention having to use a press when disassembling the housing/rotor bearings, but all the ones I've read repeat the same thing about simply tapping out the snout shaft/bearing.

I'd try the usual heat/cold triks, but if it comes to using a press, I'm sure you know to use care to avoid damage. Rebuilders all seem to have stories about s'chargers coming to them after an owner has already damaged them...

Ok I'm at the last step where you put the freezing bearing/drive/shaft assembly into the heated snout/bearing assembly. Has anyone done this before? I'm really worried that as soon as the hot and cold metals come in contact there will be a hell of a time getting it in.

This is a one time deal I can't afford to screw up.

If you've made it this far you'll get it done. I don' know how you got this far without a press? Even with a press I had to fab up a steel plate with hole and slot to get one of the bearings on/off. It's a pretty thankless job, but that's how it goes with 15 year old cars.

I wanted to put an update for others in the future. I talked to rzimmerl and he said to torch the housing and front bearing with a frozen shaft then assemble. It worked perfectly! They slid right into place. I figured putting it in the oven wasn't a high enough temp!

Basically just some gentle heat down the center of the snout with a MAP gas or propane torch.
