OK...TA Freak...checked the PS pump pulley on both my '99 Hawk and the '01 WS-6...both are mounted the same distance back from the shaft front end which I'd say approx. 1/4 inch. Another follow-up is yes installing the aftermarket idler had to shed the factory dust cover. Sounds like I need an alternator and possibly wire brushing the pulleys. Also, started to notice the
'01 had a squeal at 2000 rpm, not under and not over, so another EFFIN problem. No mods to either car and both low miles (21k-23k).
Have had 8 of these 98-02 LS-1's with only these 2 left. Know all the common problems...headlamp motors, driver's side window motor, both side door panel cracks approx. 8 inches from back of door, rear pinion seal leak, electric antenna stopping, radiator low level sensor on 98-99's, etc. Both of these are stock but I guess age is showing and making sounds. Thanks all for your help.
Hopefully the alternator will quiet the chirping sound.

red70judge, try sanding your water pump pulley so that it's smooth and see if that doesn't solve your problem. Have you ever used belt dressing? I had in the past .... so I had a build up of gunk in the pulleys. Also, have you isolated which belt - or both?
Thanks for the info on those pulleys .... and it sounds like you are well seasoned at the typical quirks of these cars. I've been there and done that on every single thing that you listed.
Lastly, what have you got under the hood of that `70 Judge? I've got a `79 Firebird 4 speed / 400. The block is from a `70 goat.

Save yourself some time and money and go out and spray some water on the ribbed side of the belt and if the chirps stop then all pulleys and bearings are fine. Also feel the surface of the water pump pulley. If it's not smooth, sand it. Have you ever used belt dressing?
