Squeal in Motor

[theeaman]

had a problem with a squeal in the motor during acceleration/deceleration; replaced the alternator & a/c belts; squeal is gone for the most part, but still shows up under heavy acceleration & deceleration.

have i over-looked something that may be to blame?

If the belts are tight, you may have early signs of the bearings on the alternator or A/C compressor freezing up. You can try using belt dressing from a local auto parts store, but my guess is you are close to replacing the A/C compressor.
