Grinding at highway speeds

Hey fellas,

I have an '01 CLs completely stock with 148,xxx miles. I did a quick search and didnt turn up with anything.

While driving at highway speeds, usually around 70mph, after about 10-15 minutes of driving I can hear and feel a grinding noise. i feel the grind in the pedal and floorboard. When I first heard the noise it would last for about 3-5 seconds and go away. Today while driving the freeway, It lasted a good 20 seconds. i pulled over to the shoulder and sat for a bit, then proceeded with no noise.

i have had no recent work done nor have i been in an accident. Totally confused and concerned.

thanks in advance

Wheel bearings or rotors. CL's warp rotors like nobody's business.
