Re: ac noise squeek

There is a bearing for the pulley that can be replaced without removing the freon. This bearing is sealed so refilling the system would not help this.

Reproduce the problem and then shut the engine off and remove the belt. Spin the pulley by hand and see if the noise happens. This will tell you if the pulley bearing is the issue.

If the noise is coming from the compressor, I doubt a drain and refill will help the noise.
