Squealing pulley

[JustBeachin]

So, I've been living with a squealing noise from one of my pullies. It would squeal a lot when I first started it up, but after a while, it would get quieter.

So Cliff and Brian come over Old School SoCalSyTy guys, and we pop the hood and Cliff listens for a while, and tries to isolate where it's coming from. So he asks if I have some silicone spray. I go look....nope. So he asks, "What about a water bottle." Sure, I always hafta put some fire out in the barbeque. So he sprays some water on the pully, belt, and squealing subsides. "Hmmmmm, maybe you should get a new belt." He says.

Then I let him take it around the block to check out the close ratio steering box. After I let Brian try it, he proceeded to go and buy one. So Cliff trys it, and he says, '"Wow, this is nice" It's Cliff's turn to get one now.


Later on that afternoon I'm out picking up milk, 5:45 on a Sunday afternoon, I swing by Autozone, half expecting them to be closed, and they're open. So my daughter and I go in, and pick one up.

So after dinner, I change it. 5 minute job, and start it up...........quiet. That's a big relief, no pulleys or water pumps to change.


:tup::tup:


Two thumbs up.

Thanks Cliff !

Re: Squealing pulley

99% of the time, the belt is the culprit of squealing. Never had one squeal after changing the belt.

Re: Squealing pulley

IMO, I’d check the bearings in the tensioner and idler pulleys. Just after I got my truck I changed the belt. Found the idler pulley retainer bolt just beyond finger tight, weird. Also the idler pulley was the “old style” plastic type. The new one is steel. I suggest it be changed if you have plastic.

Agreed. The bearings in the pully on the end of the tensioner are gone on both my trucks; not shot, but they feel less than smooth during rotation. Get the number off the bearing and bring it to the parts store, don't even bother asking for a tensioner idler pulley bearing; the moron won't be able to find it, and if they do, it'll probably be wrong.

Re: Squealing pulley

Heres one for you that happened yesterday. MY truck squeeled the same way for a few months, because I wasnt sure where the noise was coming from. Sounded like the alternater. I add a little wd-40 and check the waterpump pulley nuts. [electric fan] Nuts were alittle loose, tightned them up, and the squeel stopped. So Im in denver for the weekend, and im heading back toward Co. Spgs when I loose a serp. belt. No problem, I carry a spare. Yeah right, THE DAMN PULLEY BROKE off the waterpump! The loose nuts caused the holes to wallow and enlongate. [hence the squeel] Cycle fatigue caused cracks and ult. pulley failure. I found a used pulley from a local 4x4 shop, but had the the wrong spacing. So I super glued 4 nickles the back of the pulley to give the right offset. All this happens at 4:45 when every thing is closing. I hate working in the dark, and being on foot. It got me home!

Very MacGyver-esque repair.
