Squeeky Noise When Dryer Runs

I have a squeeking noise when the dryer drum turns or when the blower turns. Hard to tell which component is making the noise. What is the problem and what do I need to fix the problem…or do I just need to lubricate something. Please send link to instructions if possible.

Kenmore Elite Electric Dryer Model# 110 60982990 Serial# MK0705480

After further investigation, I noticed that the squeeking noise is coming from the motor when I turn it. I blew out all of the lint from the motor and it seems to not squeek as frequently. I get periods of squeeking and times where the dryer is quite. Is there some type of maintainence I can do to the motor to eliminate the squeeking noise?
