Vibration at speed. Squeak at low speed. Same part.
A U-joint is shaped like a cross with caps on each end, and inside those caps are needle bearings. When they dry out and start failing, the joint stops moving the way it should.
That's the vibration you feel and the squeak you hear. Ignore it long enough and a U-joint can let go, which turns a repair into a safety problem.
