...can you take the platter off and put it into run mode i.e. the idler against the motor spindle? If you can then put a stationary object right against the idler edge and see if there is any 'out of roundness' with the idler wheel.

A small variation in the idler will be visible but it will be tiny. If it looks perfect then look to the platter as Triode suggested. Make sure it's clean on the contact edge and clean it with a Q-tip or something else with Iso-alcohol. If you don't have Isopropyl Alcohol use Vodka

If you can spin the platter by hand with no power and idler off with nothing contacting the platter, see if it spins freely or if it seems to get hung up somewhere during the spin. Mark the rotation with a magic marker somewhere and see if the 'Mark' you've made comes to a standstill near the same spot over and over again.

You can clean up any magic marker with Iso-Alcohol so don't worry if it's on metal.
