4.0?

What year?



Is this a sustained squeal or just a quick chirp and then it is done?


What is the volt meter doing when the noise is occurring?



Alternator belt.....I replaced the alternator and belt in my 1998 4.0 5 speed Wrangler this spring and no more noise.


:beer:
 
1990 wrangler 4cl . Coolcruiserfj40 told me to check the blinker fluid and the muffler bearings but I have no idea how to check those things.
 
Its just when it starts up. and not all the time either.:confused:More like a chirp.
