High speed shake

[72Fins1]

I've been having a problem with my 94 Explorer that happens at high speeds. It does fine from until 60 mph but after that it shaking in the front. It still accelerates but the shaking doesn't quit. Does anybody have any idea where I should start to try and figure out what it is? Any feedback would be greatly appreciated and thanks for taking the time to view this thread.

Jack up each front wheel and grasping at the 12:00 and 6:00 positions push top in and pull bottom out and reverse, feeling for any play or clunking. If you have any the wheel bearings or ball joints are loose. Do the same test only using 9:00 and 3:00 to check for loose steering parts.

The Explorers are known for a shake at around 62 - 65 mph and many have spent good money chasing a solution... me, I just drive at around 60 mph on a 70 mph Interstate.
