99 Yukon belt squeak

[bigfootchiro]

ok i went and verified the clearance on the P/S pump pulley. if your diagram is right the pulley has definitely walked itself out over the years. cant even see the pump shaft i had to feel for it. its a good half inch out. so i guess its that time. i know these are a real pain to do on these trucks also. r.i.p.

truck is on its 3rd belt i ruled out defective belt a while ago. im gonna replace the pump / pulley and then the belt. if the squeak comes back i will try the sand paper idea. i have heard of these cheapo autozone belts causing squeaking. im going to go all out and go gator back lol

i did wire brush all the accessory drive pulleys including crank pulley before installing new belts in the past already. never actually tried sand paper the surface hmmm.


edit: just ordered 2 new gator back belts lol lets see how this works after the pump install

Just use a pulley puller/installer and push it back on. You’ll hear a difinitive “pop” sound when it’s set in place.

Agreed, I’d just reseat the pulley and not worry about a new pump. It really sounds like someone did work in there and never got it seated all the way on.

just wanted to thank everyone for the proper guidance here. it turns out the p/s pump pulley was causing it! I had a shop push it back on and the squeak went away instantly. i would do it myself i dont have the tool. im mechanically inclined and i would really never of thought the pulley could walk its way out that far. from what i know those pulleys usually pop into place once they are seated which is weird how it walked about a half inch out .

Haha well, possibly the first or third owners messed with the pulley. She’s a well riden Hoe! Been passed around like one, that’s for sure!
