Whirlpool LSQ9544KQ0 washer makes knocking sound on spin cycle

[lqqk_out]

Hi!
I have a washing machine that is making a knocking sound on the spin cycle.
Make: Whirlpool
Model Number: LSQ9544KQ0

This machine is probably over 15 years old. I've been maintaining it and fixing the little problems that pop up. Within the past year I've replaced:
1. Short Cam Agitator Repair Kit, CAM-AGIT, (285809)
2. Agitator Bolt Washer (3949550)
3. Thrust Spacer Washer (3951608)
4. Whirlpool Direct Drive Washer Motor Coupling (3364003)
5. Replaced the two washer filter plugs (8522271)
6. Replaced the water fill valve
7. Replaced water supply lines
8. New control timer part number: 3951702H
9. Changed (2) top console panel screws, replaced OEM size (8-18 x 1.25) with: 8-32 x 3/4"
10. Replaced lid bumpers, Whirlpool 9724509

The battle with this machine continues. I'm now hearing a knocking sound during the spin cycle.
Actually, it sounds just like the machine in this YouTube video. Unfortunately, the person that uploaded the video didn't state a fix for the issue.

Can someone please tell me what part I now need to replace? Gearcase?

Could be a stripped out basket drive block - If a steady loud knock as the washer comes to a stop this is the most likely problem.

Part number: 389140

If the knocking starts once the washer gets up to a high speed spin with an empty load check the three snubber pads under the  skate plate.

Part number: 285744
