Serpentine Belt Squealing Like A Stuck Pig? I Have A Story For You!

One afternoon I had picked a friend up from Dallas Fort Worth Airport and was headed back out of the airport. I stopped to pay the toll at the booth and pretty much floored it leaving the booth (you pretty much have to if you want any chance of merging with the rest of the INDY 500 competitors. Anyway... about 200 yards into the sprint, I heard a noise and the steering went stiff on me. I knew immediately what happened and pulled over to lift the hood and confirm... sure enough, the belt had disintegrated leaving nasty little strips of serpentine goodness wrapped around every moving part. Not a big deal I say and go procure a new belt and head immediately back to the airport for the quick fix. All went well and I cranked it up and headed on out... but I had a new friend with me that I didn't expect. It sounded like someone was trying to decapitate a pig every time I stepped on the gas. I'm thinking I still have some goodness wrapped around something that I missed in my haste to make a quick repair. I get home and went to work looking for the suspect. This was no ordinary suspect however. It was elusive and had a personality all its own! Sometimes it was there... sometimes not. Occasionally... after a long warm-up it would subside altogether. Some days it would sound like a slaughter house from the time I cranked it up until the time I shut it off. I thought I had damaged "something" when the belt wrapped itself up in "everything" leaving the toll booth. The noise was so loud and obnoxious that I couldn't pinpoint it! It was all-encompassing and seemed to be coming from everywhere... and yet nowhere! First, I fingered the water pump for replacement. After replacing that, the noise was not gone, yet its tendencies had changed. I got a bad pump! Better go get another one! I replaced that one... no dice! The slaughter house was open for business... and business was good. Well... I knew my AC compressor was not functioning well and when I spun it, I could detect "some noise" that I didn't think should be there. Better replace that! So I did! You guessed it... no dice! I get some local knowledge to try and detect where it is coming from and "of course" they figured it was the idler pulley. I replaced that... no dice. Next I move to the tensioner pulley. Without going into the gory details, I will just say that it took me 10 painful hours to change that little bastage out. This did NOT do the trick. At this point, I'm looking for PETA to show up every time I crank up my mobile slaughter house. I tried belt dressing on my DURALAST belt and what do you know! It stopped the squeek... for about a mile. Now I think I know what the problem is... a bunk belt. So I go to Autozone and pony up for the Gatorback belt and squeal on home (I was too cheap to do this the first time). I get home and change the Duralast belt for the Goodyear belt. Guess what! THE SQUEAL IS GONE! So... after spending close to $500.00 and many many hours to kill this squeal, all it was was a crappy quality belt! All things being equal, I probably could have used a few of these parts on my 1996 Grand Cherokee 5.2 with a quarter-million miles but for heavens sake! If you ever have a squeal on your Grand Cherokee... just replace your crappy belt with one that costs 15 clams more (the Gatorback in my case) and save yourself a LOT of time "and" expense! I was close to losing my sanity over this issue and tonight, the weight of the world is off my shoulders and I can ride proudly to work in the 6:30 am Dallas traffic. No more hiding my face every time I'm next to someone (which was pretty much constantly)!:cheers2:

I can only hope that "someone" will be spared the agony I went through in this process by reading this story...

I had a similar issue happen one time. I did not replace every pulley though :teehee: I purchased another belt and the squeak went away. Three weeks later it started squeaking even louder. So i put the old one back on again because i just had to see what sound it would make (i am like that lol) just a little squeak every now and again so i left that belt on. Long story short i was driving down the highway and the power steering pulley imploded causing all kinds of damage. Fixed the issues and to this day my belt will still squeak a little bit when it feels like it. :laugh:

My ZJ is squeaking at turning, when slowing down etc. I had the water pump go replaced it made less of a squeak.. but we had to take the belt off and put it back on. Now i thought it was the power steering pump... when jesus its the damn serpentine belt.

YES!

???????? No belt, engine running, no pullies, water pump, power steering pump, or A/c compressor turning, how is this going to tell you it is not the belt?:confused:

Sounds Familiar, it's never what you think:

I had a squeak,
drove me nuts for ten weeks
I told my girl I thought it was the tensioner,
she said never agian to metion it to her,
I replaced the alternator because I got the lifetime warranty
that did'nt do it, so I replaced the Idler pulley
I still had the squeak so what did I do?
I replaced the Tensioner with one less improved,
still it was squeaking, and in the end
I sprayed some TFL dry lube and it was quiet again.

And a week later it needed a new belt.

Great story

I replaced my belt and picked up a small squeel which rapidly increased to the slaughtering point. I was getting ready to replace my water pump thinking the bearing were shot. When I remembered seeing an article about a serpentine belt issue. Well yours isn't the one I original read, but I tell you I enjoy reading it. Thanks for the info and the laugh. After reading your post I tightened my belt an no more slaughtering pigs.:2thumbsup:

I had the belt squealing followed by the power steering pulley implosion, and then discovered that the culprit to bot problems was actually the power steering pump bracket cracked causing a slight pulley misalignment. after replacing the power steering pump bracket I get no squealing even with a cheap serpentine belt.

ps if you have had the belt squealing problem on a 5.2l zj I would be willing to bet that at some point you will have the power steering pulley issue and most likely your ps pump bracket will eventually fail, as there was a design flaw in the bracket (as admitted by dc when they redesigned the bracket)

i bought a cheap belt and a week later it started to squeal, so i took it off and got a new one and i noticed the new one was about 4 inches shorter, so i figured they gave me the wrong one, so i put the new one on and all was good, and a couples weeks later it started to squeal again, so i looked and the tensioner is maxed out and not keeping enough tension on it. sure enough the belt was about 5 inches longer that is should be, they kept stretching, so now i have a 120$ gatorback on it and i haven't had any issues yet, so i have learnt to not cheap out on parts.

Oooh, good thread. I've been dealing with this one myself. Sounds like the same symptoms too. Sometimes it would sequel like a slaughter house, other times less often, it wound't make a sound. And everywhere in between. At first I thought It was my A/C clutch going out, but then decided to try spraying some CRC belt conditioner on it. That quickly produced the loudest obnoxious stuck pig slaughter house sound you've ever heard. Since then its quited down but its still producing a very annoying chirping sound, like two of the loudest birds you've ever heard going at it hard.
From there I bough a cheap automotive stethoscope and checked all the pulleys. It wasn't conclusive but I'm sure its coming from power steering pump now. Ill have to look at getting a new bracket while i'm replacing the pump, and a gatorback belt while im at it.
Question, is it worth getting a power steering pump from the junk yard or should I opt for new?

Gaterback belts are junk,no better then dayco or the cheaper serp belts,they all are still made out of Neoprene.

Spend the little extra money and get the EPDM Gates belt for your older Jeep.Just by looking at a Neoprene belt and a EPDM belt you will now what one is better quality and will last 2-3 times longer also.

I wouldn't go that far, they are a pretty good belt and keep the supercharger pulley from slipping as much as other belts on my Lightning. Although I have not tried an EPDM belt.

I like that story... very entertaining to read with vivid language. :laugh::laugh:

This helps me out, since I will need a new belt soon. Now I know I need a good quality one! :thumbsup:

Hey guys, please chime in.

Mine squeeled last winter when it got cold. Drove it like that all winter.
Summer came around and it was fine all summer.

Now that temps have dropped, it's squeeling again. The squeeling is getting worse now though and I need to fix something. I have noticed sometimes that my steering gets very heavy when the squeeling is happening. My Volts also drop done to 9 volts and most of the time will just fall straight to zero. It still drives however.

Any ideas?

Yea, sounds like in your situation your belt isnt tight enough, or wasnt at one point and now may have a glaze on it...once it slicks up its pretty much done. Would seem to be logical that a warmer belt would be "stickier" and a colder belt would be "stiffer" and with just the right lack of tension you could see differences in belt traction like you are during different temps. I personally use a gatorback, I believe they have a lifetime(?) warranty and are rather high quality.

I had a similar issue and it turned out to be the magnet that engages the AC clutch. Mine worked loose from its bracket and got stuck behind the clutch causing constantly open AC. No problem at the time as it was 50*C at the time. When it did finally melt and fall out though I was not happy. Up to the JY, used AC compressor and good to go! :D

Nice story though

WOW very useful information. The squeak just started on mine. The belt is only 6 months old, and the power steering pump was replaced last year.

The Quick Oil change place I went to sprayed it, and it sounded like the neighbor's cat got stuck in there... was embarrassing to drive.

Since the crap has burned off, it's back but from a chirp that went away when warm to a quiet constant squeak.

I'm stumped what it is.... and need this damned thing running before it starts snowing or I'm screwed.

You can buy them off a plethora of online stores, including amazon.com.

I dont know how long the belts are for any of the engines, but here is a spec sheet with belt lengths and part numbers.

Goodyear® Engineered Products :: Gatorback

Figure out what length your belt is and look for the part number on amazon, and be sure to count the ridges on your pulleys to get the right number of ridges on the belt.
