Belt Squeakin again.... so so so so upset.

ive already spent 180 bucks on just belts alone... and when the OEM belt was fine before.. something had to cause this to start

 

Something is out of alignment of not spinning freely.

 

Definitely worse when its cold.. And noticed that when I left from work to go home.. It was a chirp at idle, constant squeal anything over 1500,, Slowly got better over the 20 to 30 minute trip.. Practically quiet when I got home...

 

Have you tried turning you AC on max low to see if the noise changes? Or turn the defrost off and on?

 

some have clutch fans that will start squeaking/wearing out making noise.

 

its the belt making the noise.. But something is causing the belt to make the noise.

 

Yes. Yes and more yes

 

Any update today?

 

Only thing else I can think of is one of the accessories on the engine is dragging and thats why its squeaking. Such as ac compressor...I dont think it has egr pump on it?

 

Looking at the 4.0l belt diagram, there is not a lot of belt contact on the water pump pully. You have changed the belt 5 times. Time to move on to something else. There are two things left, pully and pump. How much for a pully from the upick?

 

Can you take some pressure off the belt when the truck is running or put more pressure on it?

 

yes.. Have tried this several times. Adding pressure doesn't help. Going slack sometimes did a little, but usually caused belt to jump track

 

@Lthompson
This is about the last piece of advice here I would try other than taking to the dealer and getting warranty work. Process of elimination for repairs which sounds like you've done just about all you can do. You could always try swapping stuff out and return if no change in noise? Just a thought hope it works out for ya.

 

All I can do it just change stuff til it quits I guess. Something started it all. Because it was fine last year. Then all the sudden I'm dealing with this. So at this point I'm just replacing stuff 1 by 1. I aint takin it to the dealer though.

 

I think you should just keep changing those belts. Its only like $60.

 

Sorry if this has been suggested already but...

Have you tried some sandpaper to scuff/clean the pulleys before installing new belt? Maybe there is something on there.

If there is an alignment issue and you've already done tensioner/idler and think the WP is fine... Have you checked the harmonic balancer? I once had a balancer bolt under-torqued (other vehicle) and eventually the balancer pulley itself came forward EVER so slightly as to disturb the alignment. I replaced everything too before finding this.

 

At the start of all this I noticed the balancer wobbling, so I thought that was causing the squeal. .. So I replaced it.. ive got it as tight as I can get it with the tool I created without shearing off the 10.5 bolts.

 

Sounds like you're over torquing the bolts.

 

I'm going to guess belt tensioner but I'm probably wrong
