2000 Explorer with vibration

I have a 2000 Explorer XLT with 57,000 miles. There is a
strong vibration that increases and decreases with speed
and resembles a thumping sound under the floorboard.

Tires and brakes are okay.

Any suggestions appreciated.

I'm no expert, but I'd see if your U joints need replacement. You can do
this by twisting your driveshaft and see if there is any play in it.

Check your universal joint. I just replaced mine last night for a
similar, but very slight, vibration.
