Whirlpool washer is very loud on the spin cycle

Brand: Whirlpool
Model Number: WTW4880AW1

I have a Whirlpool top load washing machine, bought new in 2012, it’s very loud in the spin cycle and sounds like a jet taking off. Not unbalanced, just is very loud. Any ideas?

It’s been loud for the past couple of months despite it working fine otherwise.

The most common cause for the washer to sound like a jet when spinning will be that the bearings are going out and in order to correct this the gearcase would need to be replaced. Whirlpool W11454741 Washer Gear Case (AP6993917) - AppliancePartsPros.com
