What causes turntable rumble


My Rega P25 tt has begun to have a low level rumble. Never present before it is audible during quiet passages.
what causes this and how can I rid my tt of this annoyance?

rumble is there on all records and only when a record is playing. had increased VTF as recommended on a prior thread because the cart didn't sound very good and someone suggested to increase VTF to max recommended to sound better. cart has 50 hours and sounds better probably due to more break-in, but with rumble. I'll drop the VTF back today and see/hear what happens
added a few drops of sewing machine oil to bearing which was almost dry, thought not completely
