Thanks Rob, I should have said everything I already checked.
I can't say that I've "seen" the rubber bushings on the flywheel/turntable, but when turning it each way it seems to be cushioned well.
The motor is a bit noisier than most, maybe I'll take it apart and give it a good going over, or first loosen it up top and bottom and try moving it around.
The rest I had checked/lubed/adjusted already.
But right now I'm on a Wurlitzer 1400. Ugh, I don't like those mechs.

In no particular order, likely causes are:
Missing/deteriorated rubber bushings in the flywheel. These couple the drive ‘yoke” and the flywheel.
Excessive looseness in the thrust bearing on the shafts of either the vertical worm gear or the turntable shaft.
The long vertical bearing above the worm can cause flutter due to lack of lubrication. The result is often glazing of the bearing, which displaces oil. But this is often associated with a loud screech as well.
Damage to any of the continuous drive gears. In particular the fiber gear.
Badly misaligned motor which causes excessive vibration. When it get bad enough to cause flutter, you’ll feel the mach vibrating.

Trying to narrow down this annoying warble sound. Does it on all records but not always easy to hear. I only hear it in the vocals and just on the A side. B sides are OK. The motor mounts are all nice and soft as is the motor coupler. It does it at all volumes low or high, low or high bass/treble. Can a failing motor drive cap cause it? I know the motor cap is getting switched going from play to select/scan mode, that difference is easy to hear from the motor.
This machine is mine and although it's in nice condition, they are so ugly I might have to part it out. It got put aside but I have limited space for other machines in the shop so I'd like to sell it/get rid of it. I can't sell it with the warble. Any clues yet as to what is causing this? I didn't try changing the motor cap since it does it on only one side.
