I'll defer to Mat for the final answer here, but a clean and relube of the main bearing would certainly be smart. I'd also inspect the drive belts, looking for cracks. The worst that could happen there would be one might snap while you are listening. Give 'em a try first.
From my notes, here are Brent's (Brf) yearly maintenance tasks:
1) Clean and re-lube the main bearing with lithium PTFE grease. Use a Q-tip dipped in alcohol to clean out the old grease. Check the ball bearing tip for any flat spots. Apply a small amount of lithium grease on the ball bearing itself.
2) Place one drop of light weight oil below the brass collar on the motor shaft - If your motor is running quiet, I would not concern myself with lubricating the motor shaft. To do it correctly requires removing/adjusting the brass motor collar which can be tricky.
3) Place the o-ring drive belt(s) into boiling water for 20 seconds
4) Clean the phono rca and ground connections (pipe cleaner + DeOxit)
5) Clean the cartridge pin connectors (pipe cleaner + DeOxit)
6) Check the table for level
7) Check the table for correct speed
You might also consider a tear-down and rebuild of the tonearm lift. Try a viscosity of 300K cst. It can also be done with 500k cst which allows the tonearm to drop even slower. Personal preference.

Nice. Those are a far better choice!

The bearing on my platter (hw19 mkiv) is "opposite" than that in the video. The ball is at the bottom of the shaft that is attached to the platter.
I remember briefly that lubricating this one is different than the video - I'm supposed to use oil instead of grease? I think I tried grease once and it was a disaster - lots of friction.
Can I use a few drops of food grade mineral oil?
Thanks!
