When I record or play back a tape on my VCR (Sears brand), The unit
makes a rather annoying squealing sound like a cricket. Certainly
this can't be normal. The VCR is about two years old. Don't remember
this being a problem until recently. There is no audio or video
distortion. How does one eliminate this noise?

Some VCRs control the speed of the head drum by providing a motor that wants to turn it slightly too fast and using an electromagnetically controlled brake. Some such brakes are eddy current brakes [no mechanical contact] but others are mechanical [ecch]. Probably you need to have it done, but it shouldn't be too expensive.

Another possibilty for the crickets is the grounding button on the head cylinder. This is a very common problem with many major brands. Upon examination of the head cylinder where it mounts to the shaft, you will likely see a kind of leaf spring riding on the shaft. Sometimes, the spring shifts a litlle off center, hence, the noise as it touces parts of the head cylinder it is not intended. If this is your problem, it's easy to check and very easy to fix (just looses the set screw and move it back where it belongs).
