After watching a couple of You Tube DIY videos, I figured out how to open the dryer up. Initially I thought it was the bearing or drum belt. After opening up the dryer, it was assumed that it might be the missing felt that was causing the squeaking noise. Thanks to AppliancePartsPros suggestion to buy the bearing slides along with the felt that made me realized what the root cause was. There was only 1 bearing slide left on the dryer drum front support bearing because it was so broken. With all new parts in place, the squeaking noise is gone! Thank you, AppliancePartPros!
