pulley problems

[Ogrestiva]

I think the pulley on either the ac pulley or the alternator pulley is going bad. Is there a good way to tell if it's the actual pulley or if it's the alternator that is going bad and if its the pulley, can it be replaced easily or is it better to get a new alternator? When I start up my car one of the pulley's, I think it's the ac pulley,(I haven't been able to pull off the belt yet to tell which it is)is making a wobblie-scraping sound. If the a/c pulley is bad is it easy to fix?

Never known a pully to go bad. Could It be you just need to tighten up the alt. belt? Sometimes there bad about loosing up.

A/c clutches, and alt bearings within the unit can go bad. Take the belt off and wiggle the alt pulley to check for play. Any significant amount of 1/8" or more is sure signs of part failure. Check if the a/c pulle y binds or sticks...as well as the clutch.

If its the A/C one just pull the belt off. Packrat had a waterpump pulley crack around the inside and come apart. With the engine running look to see if a pulley is wobbleling.

The bottom pulley that attaches the a/c belt does look as if it is wobbleling is it ok to just pull the ac belt off and drive the car without the ac belt?

[festivaWES]

yes.

AC belt only drives the compressor.
Alt/Water belt are a single belt, lose that and you need to pull over and shut down!
