horrible squeak

Hey guys, I have a GE electric dryer that is probably a little over ten years old. It makes this horrible squeaking noise w/ every rotation. I was wondering if there is a grease fitting that needs attention or if anyone might know how to make it a squeakless laundry experience. Any knowledge would be appreciated.

Here are your parts

Could be a bunch of things so you will have to open the unit up to find the cause.

The most common cuase in these units is a dried out or worn rear drum support bearing.
If it needs re-lubing be sure to use a high temperature grease.

Could also be the front drum support, belt idler wheel or motor bearings.

This is agood time to also check other internal parts and give it a good cleaning.
I would also check/clean the vent system.
