I did research on you tube to find a video of a repair for this issue. All, including Appliance Parts Pros recommended replacing the drum support rollers. There are 4 on my particular dryer so I ordered 4 just in case. I watched the video a few times and was confident that this was the problem. When the rollers arrived, I took the dryer apart. I did find the blower fan plugged with lint and hair that went almost 3/4's of the way around the fan. The fan spins at a high speed and it being unbalanced would have certainly cause the vibration and noise we were experiencing. I removed all the lint and cleaned the fan. I took apart the rest of the dryer to get to the rear rollers and found 1 roller a little stiff. I elected to change out the two rollers in the read as they are the hardest to get to. The front rollers were in good condition, no binding or wear. After putting the dryer together the noise and vibration was gone. I'm pretty sure the cause was the lint packed fan more than the rollers so definitely check that first, it may save you some time and you don't have to disassemble the entire dryer to fix it.
