It is a rather involved job to replace the bearings, it will involve removing the A/C clutch and disassembling the compressor. I would check to see if the noise is coming from the A/C clutch or the compressor, itself. The A/C clutch isn't to hard to replace. I would really consider a replacement compressor.

You don't you change the compressor. but i would try putting lubricant into the system first. over time the system can lose freon and with it will go the lubricant. if it gets too low the compressor may be damaged and sometimes replacing the lube will bring it back to life. you should try before replacing the compressor. good luck

You change the entire compressor. May not be compressor

Ac makes whining noise on a 2004 Pontiac grand prix

Is the whining noise coming from the engine compartment where the compressor is located or is the noise coming from inside the car? If the noise if coming from inside the car it could be your blower. When a blower wears down the bushing is the first thing to wear down and it begins to have play. That makes the blower/fan vibrate making a loud whining noise. Replacing the blower could solve that whining noise.
If the noise if coming from the AC compressor, it also could be a bad bearing within the compressor.

Grinding noise coming from alternator or A/C compressor, now engine does not turn off...

Lot of time the A/C compressor bearing brake and lock the belt. After the engine shut down the belt melt and stick to the compressor pulley. remove the belt and start the engine shortly. replace the compressor clutch and bearing or sometimes is better to replace the complete compressor.
Good luck

My 94 grand marquis shut off seconds after a loud grinding noise that sounded like it was coming from the front left hand side. I tried turning it back on after it happened and the check engine and oi

I interpret this as the Passengers side of your car. Usually the serpentine belt breaks when the A/C compressor seizes. That is the part which is probably grinding or the A/C clutch bearing is seized.

Although this is Winter, the Defroster is made to activate the compressor to lube it during the Winter. Now the pulley that turns the compressor has a clutch bearing. It is ALWAYS turning when the engine is on except when electricity is applied to the compressor clutch and it locks and turns the A/C compressor shaft.

What needs to be done now is to determine if the A/C clutch bearing is bad or if the A/C compressor is bad. Most A/C clutch bearings can be removed and replaced. SOME of the bearings within the A/C clutch can be changed and then they are as good as new.

The procedure for replacing the bearing is 1 step beyond replacing the entire A/C clutch. The fan shroud must be removed, the serpentine belt must come off, then a small bolt and a retaining clip must be removed and the clutch slid off the compressor.

There is no need to remove the compressor or lose Freon. The bearing situation can be determined once the serpentine belt is removed and the parts turned by hand.

How can you tell if the a/c clutch or the a/c compressor is going out if the noise is coming from the same location as well as the compressor still blowing cool air?

This answer is a little tricky to understand unless you read it carefully.

The compressor clutch has an idler bearing in it. This means the clutch can constantly make noise while it turns and the compressor is off. On an individual basis, each bearing is unique by the amount of bearing wear has occurred. Most will be quieter when engaging the compressor in "lock" position, but a bearing missing rollers can be loose in the locked position and be lopsided in how it grips the compressor. The pulley will not roll true or straight to the rotating compressor shaft.

The compressor can make noise separately from the clutch because it needs an internal oil supply for its bearings. There are A/C oil cans and
Freon cans with oil in them. Just like motor oil, there are differences in what type of oil the compressor takes. It is relatively inexpensive to add this type of oil to renew the life of the compressor.

When the compressor is turning, the inner pulley will be locked to the front pulley clutch and both pulleys will be turning. If there is a rumbling sound, it is likely the compressor, but try oil first. The compressor is a pump. It is not silent. You can expect to hear the muffled chirping or clicking of internal valving as it forces compressed gas or liquid past the valving. The valving clicks or chirps as it keeps the flow from backing up into the compressor head.

For a time, the compressor will cool as long as it turns and the clutch turns the compressor shaft. If the bearings inside the compressor seize up, it will probably break the serpetine belt. If the compressor clutch bearings fail, they will start making noise both when the A/C is off and when the A/c is on.

Many times a clutch will be changed only to find that the compressor is also bad. It is not a 1 to 1 relationship. A guess would be a 1 in 10 or 20 occurrence. And it is something even the best mechanics may misdiagnose. This is why sometimes a compressor is included as part of the total estimate, a worst case senario.

The noise is your A/C pump clutch bearings. You can have the clutch replaced or possibly buy the belt for the truck that didn't come with A/C and it may fit without routing it around the pump pulley. If you leave it, the bearing will eventually fail and the belt will shred. You'll lose power stearing, cooling and charging...not good.

Ac compressor clutch is making a noise is the clutch is replaceable without replacing compressor

I had the same issue with my 2006. I thought the compressor clutch bearings were faulty. After further research, the rattling noise was actually coming from the serpentine belt tensioner. Easy repair!
Hope this helps.
