Furnace

My bedroom furnace squeals upon start up then quiets down.  It's the original furnace. Is it very difficult to pull it out and rebuild or replace? Can I still buy a new unit? 1996 U295.
Thanks

How do you get to the motor shaft bearings?

Access the furace from the outside.  Locate the two ends of the motor shaft. 

Use a light viscosity non detergent oil (sewing machine oil is a good choice).

I put a drop at a time on the end of a long screwdriver and "drop it" on the shaft as close to the motor as possible.

Put 4-5 drops on each end of the motor. It will wick in to the bearing/bushing area.
