Default Hot vibrations?

Couldnt think of a better title. This same thing came up last year. Ill run my 93 up to temp/188-193 runs strong no miss plenty of power. Then ill get a vibration or fast thumping from what seems under the car. Ill put her in neutral and its still there. It will usually go away after a while. Didnt happen during winter. I replaced u joints. What will cause this in the drive train when it heats up? Hub bearings? Half shafts? Rotor? Ive checked all wheel lugs. Brake pads were replaced last year. Rotors (look) good? Thanks Dave

After listening on way home yesterday in 90+ heat it seems to be coming from right front. I lightly touched brake and it seemed to stop or let up some. Any thoughts?
