Bought a Lionel SRR PS4 with TMCC. Made about 2005. After about a week it started squealing when running. My question is do I need to remove all screws on the under side plate that holds the drivers on to reach the gears and driver axles? Thanks.

Squeaks can come from alot of places, the pickup rollers, pilot or engine truck, the shaft bearing on the can motor.
I would try to narrow down the location. If you've lubed the axle bushings and gearbox, typically the gears don't squeal.

This locomotive does not have a removable bottom plate.
Remove the grease screw and put .5-1.0 mL of grease in there and put a drop or two of light oil on the axle between the frame and each driver.
Make sure you oil all the pivots and valve guides of the drive rods as well.
If you don't have the owners manual see pg 28 here: TMCC PS4 Owners Manual.
This should prevent any noise from these areas. Again, axle bearings and gears usually don't squeal. Its typically the pickup rollers or the shaft bushing on the can motor that do.
If its a high pitched squeal I'd be going after the motor shaft bushing. This is more involved and requires removing the shell.
