My air conditioning compressor recently started squeaking while the compressor is engaged. Turn AC off & no squeak. I'm thinking bearing but haven't found a diagram to know that can be changed.

I recently did the heater core and the AC is cold. The less I have to disturb the radiator or AC the better. The usual "I want to be down as little as possible" applies.

So...Can the bearing be replaced?

Can it be replaced without removing the compressor?

Does the radiator have to come out?

Is the bearing a Dodge only part or is the bearing a standard size?

We have a bearing supply house & I could order from there if only the bearing needs to be changed.

It looks like bearing would be pressed into the pulley (P1 #3) of the pdf. In which case, I may be able to press out & simply replace. Comments?

If it does it only when the compressor is running, then the compressor itself is going or the clutch isn't engaging all the way.

 

What part of the compressor? Clutch can be replaced. How do I test for which it is?

 

Remove the belt then check the pulley for play.

 

before replacing anything check voltage at clutch by backprobing at connection, squeaking is usually clutch slipping

 

Thanks. That is an idea I hadn't seen. Much too expensive to mis-diagnose & install the wrong parts.

 

Check your air gap between belt pulley and the part that attaches to compressor, proper spec is available from dodge or compressor mfg. I have a compressor manual if need be. You will need a special tool to remove part and remove shims untill proper air gap is set
