Sounds like you have a bearing failure either in the extension housing or at the rear of the impellers.
you can remove the extension housing by first removing the pulley at the front and removing the bolts at the rear of the housing where it meets the main body of the supercharger and slide it foreward if there is room.
I stripped down my supercharger after I had it reconditioned because the mechanic had left a small piece of aluminium shaving inside it and it jammed the impellers and it would not turn at all, I replaced all the bearings and seals as well and have had no more trouble so far.
I hope this helps you.

How do i time my Golf 1 correctly? it consumes a lot

its tricky enough if your not sure what your doing but ill run you through it. 1. remove top rocker cover and timing belt cover. 2 make up the position of the pully on the cam shaft at the top and the drive shaft at the bottom, this marks are you fail safe incase you cant time the engine. 3 remove the timing belt and pully tentioner, note if your going this far you are as well to replace the timing belt,tentioner and water pump. 4 On the cam shaft at the top if you force them to turn you will see a small indicator mark on the shaft this mark has to line up with the other indicator mark on the housing between the cam shaft and the cam shaft pully, once they line up your top end is timed, mark up the pully incase it moves. 5 on the drive shaft pully there is also markings that have to line up but you can also feel the position of the pully as you turn it, you will feel the piston been forced up and it is timed at top dead centre on cylinder one, which means the the piston has to be at the top just before the point of returning back down, using your feeling as a guide and the markings lined up you will have timing. also mark up this pully, your new marking should be very very close to the fail safe markings you put on at the start. when you have your marking replace the timing belt with the longest distance between pully contact going on first, try not disturb your timing or your hard work will have been for nothing, make sure the tentioner on the belt is tight but not to tight to the point where you ll stretch the belt or snap it, put everything back as you found it and crank the engine, job done, best of luck. hope this helps( rate me on my answer thanks )

Crank shaft pully makeing a lot of noise

needs to be replaced, rubber bushings are possibly worn causing these noises. This could eventually allow the outter and inner parts of the pulley to separate.

Serpentine Belt Alignment

you shouldnt have any allignment issues, assuming that the pully is good. if it needed to be replaced, you would know it. you would hear all kinds of odd noises...but my guess is that when the tension was put back on the belt, it was overlapping one of the edges on a pully farther down. just take a close look at where the belt is routed, and make sure that it is on its track on every pully. if not, release the tension, reallign, and tighten up again.

I have a high pitched noise which appears to be coming from front right engine compartment (as you are looking at the engine) which sounds kind of like a belt that is squealing. It is intermittent. Just...

Could be several things. WHICH ENGINE?.. 4 cylinder (has three belts, power steering/water pump, alternator & A/C compressor, one tensioner pully A/C compressor), The V6 2.7 (has only one belt, 1 Idler pully and 1 tensioner pully), the V6 3.5 has two belts - A/C/alternator, and power steering - there are two tensioner pullys). Noises can be caused by the belt(s) themselves, pullys, bearings, pully bearings, water pump shaft bearings (or belts/pullys rubbing up against something). Let's not forget that there is also belt(s) behind the Timing Belt cover as well as pullys and bearings associated with the timing system. You could start by removing one accy drive belt at a time (alternator, water pump, compressor, power steering, etc) to see whether or not the noise goes away in each case. If after each case, you discover the noise is still there, it's probably behind the timing belt cover (idler/tensioner pully, water pump shaft bearing, crankshaft bearing, etc.). Good Luck

Replace water pump for a 1988 pontiac grand am

The pullies have to be pressed off. If you have an AutoZone close by, they can take them off for you.
Do Not hammer the pullies onto the waterpump! Place the pullies face down on your bench or hard surface and tap the pump into the pullies using a punch on the shaft only!
