JohnQ Posted February 19, 2007 Share Posted February 19, 2007 Any ideas where the darn squeaking is coming from? I just changed my fan clutch and will be changing my water pump sometime this week. I gave all the pulleys a nice bath in WD40 and I loosened my belt to see if that would help, but nothing. :wrench: Link to comment Share on other sites More sharing options...
BIGMASS Posted February 19, 2007 Share Posted February 19, 2007 Sounds like you may have some bad bearings in a pulley or two. Remove the belt and check each one for smooth rotational movement and any side to side or in and out play. Link to comment Share on other sites More sharing options...
87manche Posted February 19, 2007 Share Posted February 19, 2007 that's an odd one. when you stepped on the gas it went from a light squek squek heavy squeak to heavy heavy heavy. So it sounds like a shaft is moving when you step on the gas. check the alternator bearings. Alternatively, get yourself a large section of rubber hose and use it like a stethoscope, just be very careful not to get it into the belt/fan while the motor is running.

Remove the belt and check each one for smooth rotational movement and any side to side or in and out play. This is what I would do.... I would think it was the Alt OR the idler/tentioner pulley. (If yours has one. ;) ) Also WD40 is a SUCKY lubricator!! It works good for removing crayon marks from the wall and displacing water under your dist cap, but thats about it!! Keep it OFF the belts!! When youa all done, I would replace that belt. Its likely, at least PART of your noise. GOOD LUCK, CW Link to comment Share on other sites More sharing options...
JohnQ Posted February 20, 2007 Author Share Posted February 20, 2007 I give up. I pulled her all apart again and couldn't fine anything that would be suspect. Tomorrow I will limp her down to the Firestone experts and see if they can find the problem. :headpop: Link to comment Share on other sites More sharing options...
feerocknok Posted February 20, 2007 Share Posted February 20, 2007 I would think it was the Alt OR the idler/tentioner pulley. (If yours has one. ;) )CW :agree: Pull your belt off and spin the pulleys by hand. Link to comment Share on other sites More sharing options...
BIGMASS Posted February 20, 2007 Share Posted February 20, 2007 If not pulleys or alt bearings it could be alt brushes too Link to comment Share on other sites More sharing options...

(If yours has one. ;) )CW :agree: Pull your belt off and spin the pulleys by hand. I did. Nothing seems worn or making any noise. The alternator only has 25 miles on it. :hmm: I think it may be my water pump, at least thats where the sqeaking seems to be coming from, it's too hard to tell.

BIGMASS Posted February 20, 2007 Share Posted February 20, 2007 Did you run it with the belt off? That would narrow it down alot and let us know if we are looking in the right place :dunno: Link to comment Share on other sites More sharing options...
watchamakalit Posted February 20, 2007 Share Posted February 20, 2007 Check the balancer. Make sure it isn't hitting the timing cover. If it is the rubber isolator in it is shot. Just went through that with the wifes xj. Link to comment Share on other sites More sharing options...
JohnQ Posted February 21, 2007 Author Share Posted February 21, 2007 I ran her without the belt and no squeaking. I took my alternator to the autoparts store to have it checked and no squeaking. So while I was there I went ahead and ordered some new pulley's. Should have those on tomorrow. Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted February 21, 2007 Share Posted February 21, 2007 don't forget....buy a new belt!!!! :roll: :brows: CW Link to comment Share on other sites More sharing options...
JohnQ Posted February 21, 2007 Author Share Posted February 21, 2007 Ok, new pulley's are on and still the same damn sqeaking! :headpop: The only things left would be the water pump, the power steering pump, or the bearing behind the cooling fan pulley. How do I change the bearing behind the fan?? Same stupid squeaking with the new parts. I will be putting the new water pump on this weekend, hopefully that will help? :roll: Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted February 21, 2007 Share Posted February 21, 2007 OK, How about trying something strange....Rig up something to spin these items individually. you will need something to use as a belt. A Drill motor with something "chucked up" to run the make shift belt on. You will be able to spin everything sans the bottom pulley. That one can be spun by simply starting the jeep. (don't run it too long....) I keep thinking your noise is belt related.....I didnt see you say you changed the belt itself. The one you have on there "LOOKS" good, but still could be causing this noise. If cash is really tight, you could buy it, put it on. then run it long enough to rule out or in the belt. If its NOT the belt. Remove it and return. No harm no foul as its perfectly good for the next guy. but then you will have ruled OUT the belt itself as the culprit. GOOD LUCK!!!

BIGMASS Posted February 21, 2007 Share Posted February 21, 2007 I listened to both sound clips and it seems to be better, no? I will be putting the new water pump on this weekend Is the water pump known to be bad? If so it could cause such a problem. What all pulleys were replaced?

It's not bad, it is just a suspect for the squeaking noise. I already have a new one, so it can't hurt to change it. The only problem is that I have never changed one before or messed with the closed coolant system. I don't have a clue what to do first. :wrench: Link to comment Share on other sites More sharing options...

watchamakalit Posted February 22, 2007 Share Posted February 22, 2007 before you tear your motor apart try listening. Get a long pry bar or screwdriver or something metal. Put it against the waterpump and put your ear up to the other end. You should be able to hear the squeak. You might also try a mechanics stephescope. Or a piece of vacum hose will work too.

JohnQ Posted February 25, 2007 Author Share Posted February 25, 2007 I drowned everything in silicon spray and the squeaking stopped. :D I am still going to replace my water pump before I don't have a choice. Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted February 25, 2007 Share Posted February 25, 2007 I was thinking about you and this thread today as I was swapping out my alt. It $#!& the bed last night!! Luckly I have a spare or two!! :D :brows: It wasnt marked for output. The one in th MJ, that went bad is a replacement. I do not have AC so I am assuming it is a smaller unit. the one I swapped in was from a XJ limited with power everything as well as AC. So I am going to assume it is of a higher output.

Pete M Posted February 27, 2007 Share Posted February 27, 2007 The idler pulley in my minivan squeaks and we touch a bar of soap to the belt to make it shut up. :D Cheaper and lasts longer than belt dressing I tried. Link to comment Share on other sites More sharing options...
JohnQ Posted March 8, 2007 Author Share Posted March 8, 2007 don't forget....buy a new belt!!!! :roll: :brows: CW The silicon spray lasted for about 15 minutes. Put a new belt on her today and no more squeaking! :D Link to comment Share on other sites More sharing options...
