General Electric DBVH512EF0WW Electric dryer squeaks as soon as you turn it on. Replaced the belt squeak stopped but returned after a few more loads. What else can be causing the squeak?

That dryer has a drum bearing that needs to be replaced. You buy a kit and lubricate well with white lithium grease. If you will tear it down and clean it and grease all bearings once a year it will never wear out. You will need to totally tear it down, which is a simple job, and clean all air ducts, including the filter duct and blower wheel. Wash out most parts except motor.

I hope this helps. It's really easy to do this since several women have done it with no problems. Just move dryer to garage and get help in positioning drum and bearing because that's the place for problems.
