Engine/Transmission (1998.5 - 2002) Squeaky Pulleys

[MLeppen]

Hi All,

This is my 1st post ,longtime lurker. My truck has developed a loud squeak on one of the pulleys. How would one tell what pulley is squeaking?It sounds like all of them are doing it but know it's just one,Ideas? Truck has 62k

Pulleys

Maybe loose belts or bad bearings in pulleys. If it's on shut down it because of having a auto transmission.

Is it when you shut it down?

If it is it is a known problem with these trucks,put a Gatorback belt on it from Goodyear and it stops this,my old 2000 did it and so does my 2004.

If it is a pulley doing it when it is running,then you probably have a bad pulley,there are some after market pulleys out there that are better than the OEM,you can do a search to find it.

That's the first time I have heard this for a reason. Why would the Auto cause the infamous "stop squeak".

Chipstien,



The story I heard was because of the super quick stop the engine makes because it doesn't have the heavy fly wheel but my manual has done it a time or two, not nearly like my old 93 auto did though.



MLeppen,



If it's a running squeak, it could be anything that's turning but something that usually shows up this time of year is a bad clutch assembly for the A/C, that'as usually more of a ringing / clanging type of noise. Have you replaced the belt recently? Other good culprit is the tensioner pulley.

If you suspect a bad idler, take the belt off and spin your suspect. Check the pulley surface for irregularities and spin it. Trust me, a bad bearing is obvious.

Well duh..... Of course, sometimes the most obvious reasons are the ones you overlook. Forgot about the Flywheel.

Yeah it's definatly a bearing squeak. I just hope it's not the a/c bearing, that seems like it would be a pain to fix.

I had the same problem years ago. Went out and picked up a cheap stethoscope with probe type setup from a parts store. Very easy to isolate the squeak source. Watch out while the engine is running and working around all the moving parts. If you catch the hose part you could rip your ears off. Then again you wouldn't hear the squeak anymore. Problem fixed.
