How do I know if my AC compressor bearings are bad?
How do I know if my AC compressor bearings are bad?
A worn bearing will produce a high pitched squealing or grinding sound, while a seized bearing will produce a grinding noise or a noticeable belt squeal. Due to the complexity and nature of how compressors are assembled, it is usually easiest to replace the entire compressor instead of attempting a repair.
Can you drive with a bad AC compressor bearing?
You will be fine as long as you don’t need or want AC in your car. If the clutch doesn’t work properly, you will still be able to drive your car. A damaged or failing compressor will not be able to properly regulate the refrigerant flow in the AC system, and as a result, the AC will not function properly.
How can I tell if my AC motor bearings are worn?
You can usually recognize the presence of worn bearings because the motor makes a rattling sound. Confirm that the power supply is off. Never attempt to replace bearings on an AC motor if the power supply is connected. Locate the screws on the AC fan motor housing; there are usually four to six, equally spaced.
Where are the bearings on an AC fan?
All motors, including alternating current (AC) fan motors, have bearings fitted between the armature and the motor housing. The bearings allow the armature to rotate freely without causing friction.
How do you replace bearings on an AC motor?
Never attempt to replace bearings on an AC motor if the power supply is connected. Locate the screws on the AC fan motor housing; there are usually four to six, equally spaced. The screws hold the two halves of the casing together. Use a screwdriver to remove the screws.
Why is the pulley bearing on a compressor hard to remove?
The pulley bearing is pressed onto the aluminum casting of the compressor body so you are not prying against the compressor shaft. The bearing can be hard to remove because the steel bearing in contact with the aluminum frame will cause a dissimilar metal weld. Clean off all the surfaces and threads using a wire brush and / or some sand paper.

What’s the difference between a bad bushing and a bearing?
A bad bushing will ‘scream’ or ‘screech’ while a bearing will make a ‘whirring’ or grinding sound. The noise was definitely a bearing sound. I listened to the noise with a mechanics stethoscope and determined that the noise was either coming from the air conditioning compressor pulley bearing or the belt tensioner.
