Normally this is the bearings going bad.
Possibly and it can be the drive belt making a noise. It you hear a whine it is likely the alternator bearings are shot. You can remove the alternator and have it tested at most auto parts stores, after you make sure the belt is good.
If your 88 CRX SI alternator belt is making a strange intermittent noise shortly after changing the alternator what's wrong, the belt tension could be off. Adjust the belt slightly.
im not sure but in my 2000 Plymouth neon my alternator has been making squeeking noises in the morning when its cold and just recently its been making a clicking noise as the engine is ruvving down or sometime ruvving up, not sure if that has to do with the alternator
Could be you have a bad belt or belt is loose.. Also it might be possible that the bushings are worn out of the alternator
How do you replace an alternator on 2008 dodge Avenger? My car is making a whining noise and this may be the problem.
If bearings go bad on a alternator/ will make a grindind noise or long squilling noise.. but if only electronic's inside alternator are damage no noise wil be heard
In my case the bearing went bad and "froze" making a loud noise and making the fan belt smoke. If it does not make a noise, check the voltmeter on your dash - failure to charge could indicate the alternator is not working, but I think others things are more likely . It should be easy for a mechanic to test to see if the alternator is charging.
If i am correct, this is the alternator.In police vehicles, such as the P71 Ford Crown Victoria, the noise is much louder and happens more often when idling due to the higher end alternator in place. A quick search on Google for "Alternator Noise" will head an answer....
It sounds like the alternator belt is slipping with the high electrical load. Tighten or replace the alternator belt.
replace alternator belt
check for bad bearings in alternator OR TALK BELT OFF THEN RECRANK. IF STILL MAKING NOISE SPRAY WD 40 ROUND YOUR THROTLEBODY. CAREFUL IT IS FLAMEBLE. SEE IF NOISE STOPS OR QUITENS. I RE-BUILT MY ALTERNATOR YESTERDAY SILL MADE NOISE, CHANGED BELT AND BELT TENSONER LAST NIGHT THEN IT MADE NOISE AGIAN. WHILE IT WAS MAKING NOISE TODAY ME AND MY SON TOOK BELT OFF STLL MAKING NOISE "NOT BELT OR ANY PULLIES" SPRAYED THROLTE BODY WD 4O FOUND IT IS SUCKING AIR WHERE CABLE WORKS THROTLE MAKING THE HIGH PITCH LOAD NOISE. THE NOISE GOES AWAY WHEN SPRAY. WASTED 135 YESTERDAY ON PARTS
If the Chrysler is only making a clicking noise and will not start, check the starter. Also check the alternator, and the battery. The starter solenoid is more than likely the reason the car is clicking and not starting.
