REMOVAL

Disconnect negative battery cable.
Remove supercharger drive belt.

NOTE: J34730-1 Fuel Pressure Gauge or equivalent required.

Disconnect the negative battery cable, to avoid fuel pump turn on, if an accidental attempt is made to start the engine.
Loosen the fuel filler cap to relieve tank vapor pressure.
Connect the fuel pressure gauge to the pressure connection. Wrap a shop towel around the fitting while connecting the gauge to avoid spillage.
Install bleed hose into an approved container and open the valve to bleed the system pressure. Fuel connections are now safe for servicing.
Drain any fuel remaining in the gauge into an approved container.
Remove injector shield.

Remove fuel rail with injectors attached.
Disconnect intake air duct.
Disconnect EGR pipe from supercharger.
Remove throttle and cruise control cables and brackets from throttle body.

Remove supercharger to manifold bolts and carefully lift supercharger from engine. (Note alignment pins. Do not drop supercharger onto manifold.)

Thanks! I'm not in danger of replacing the supercharger until the weather gets warmer. But I'm sure your response will be quite helpful at that time.
My Buick has nearly 200,000 miles and has been running unbelievably well until the last few months. Best car I've ever had! A clattering/knocking sound is coming from the pully end of the supercharger, with hard acceleration loses power and knocks, and also idles rough. I'm wondering if replacing the supercharger will address all those issues.

check the tensioner and

check the tensioner and pulley frist, mine was making a chattering just befor i put it away this winter"98 gtp", i thought at frist it was charger but after isolating it turned out to be tensioner. anyway check pulleys and belt for any build up in the groves.
