I determined area of dryer where squeak was coming from. In my case it was towards top front of dryer.
After reviewing appliancepartspro fix it video, I removed the top and front of the dryer to assess the problem. I determined the parts I needed, front support bearing, all 4 bearing slides, felt duct trap and new bulb. I then placed my order for replacement parts.
When parts arrived 3 days later, I reviewed the repair videos, then installed the parts. Time involved 1/2 hour takedown, 1/2 hour reinstall parts. Plus time to watch videos. I vacuumed out all dust and lint from dryer, and cleaned exhaust pipe while waiting for parts to arrive.
