Loud pulley noise from A/C unit

There is a loud noise coming from my 2000 Jeep cherokee 4.0 engine. Seems to be coming from the A/C unit and the pulley attached to the unit. Found shavings around and near pulley. Pulley has ceized once. Not sure if the whole unit should be replaced or just the pulley and bearing. Is this a job for the shop or could i figure it out and do it a t home?

For the price of a new pulley and bearing assy. and labor, it might be cost effective to get a remanufacterd unit and replace it yourself. When you tighten up the belt, don't overtighten.

I have a 2000 jeep grand Cherokee limited and when i turn my air on one of the pulleys hangs up and sticks making a loud squealing noise. what is this part call and how easy is it to fix.


More than likely your air conditioning compressor has tied up. Not terribly difficult to change, however you need to have your freon removed, and them replaced after the repair.

2000 jeep grand cherokee has a loud knock in engine. Started out as a ticking sound like a lifter, know it is a loud knock. This is a V-8 Engine


If the noise still sounds like it's on top, I'd remove the valve covers and check the rocker arms to make sure they aren't broken or worn. Also crank the engine over and observe how far each travels. If any are different, a lifter or lifter and cam have gone bad.
If your oil pressure is low or the noise is deep inside the engine, likely you have a crank bearing problem. In most cases it's more economical to get a scrapyard replacement rather than do a rebuild.
Before doing anything like that, have an experienced tech listen to it. Only other thing that can make a noise like that is a broken flywheel. A good tech can tell the difference between noises and give you better advice than I can because he can hear it.

Cherokee intermitant grinding noise in neutral


Is it when the engine first starts? It sounds like to me that the starter is getting stuck in the fly wheel. what happens is when you go to start it, the solenoid push's the gear out and spins the gear almost one full action, the grinding noise could be the starter staying engaged after the motor has starter but quickly comes out of it after driving out of it. just a thought.

The 4 wheel drive on my 2000 jeep grand cherokee


The ticking noise is most likely your tranfer case chain. the chains in this case...overtime....will stretch, causing the chain to have enough slack the hit the bottom of the case.

Had belt squeal, treated w/belt dressing now loud clicking


Stop!
One of your pulleys is seizing. Most likely the a/c compressor or the tensioner (idler pulley).

Use a helper.... turn OFF a/c and have someone start the car. Observe the pulleys and see if the center one quits turning or is the source of the noise.
If can't determine and no noise, turn ON A/C and observe.
You will find it, but stay out of the line-of-fire if the belt breaks... it will be slingshot out of the engine compartment!!

Loud squealing sound in my engine


Try removing the belt and turning each pulley by hand. If everything is smooth and free, with the belt still off, drive down the block once and see if the noise is there (this will eliminate all rotating accessories on the front). If you hear the noise, then there is a problem deeper inside. Oil pressure is good? Dont' forget when doing this, you will have no power steering, so be careful.

Loud pulley noise coming from A/C unit?


it sounds like the bearing is going bad in the pulley through chrysler i believe you have to replace the whole unit. to do this you will need to recover the freon from the system which makes it hard to do at home

Loud noise that seems to be asociated with the A/C unit and pulley. Pulley seized at one point but worked the next time the jeep was started. (2000 Jeep cherokee sport 6cyl. motor) Not sure if the whole...


if the compressor is not dammaged you can just replace the whole clutch assembly which comes with the a/c clutch coil, and bearings and the clutch plate i would suggest you to seek proffessional help on this one cause it needs special tools and equipment because of freon or r134 in the system!!!!
