I have a 03 Toyota Camry, when driving about 60 and pressing on the gas it stopped accelerating. I could not accelerate above 55 - 60. At slow speeds it seemed to accelerate fine. No loud noises just a humming when trying to accelerate

SOURCE: loud hum from front end-99 blazer 4x4

Sounds like the front hub bearing assembly.

check the fuel filter and when was the last time you had a tranny service done and a tune up also check the drivebelt

I have the same car. So far no problems with the Transmision. I had the Trans oil change out every 60 K Sure sounds like you need to get the Transmision checked. Is the fault light on. I have invested ina fault code reader sure is worth it. 
Good luck.  Vilmos

it may be just sound of uneven wear of tyres

From what you are describing it sounds like it must be a valve lifter sticking. Try putting a cup of transmission oil in your crankcase, or pick up some suitable additive from your local parts store. I wish i could hear it and give you a better idea. Maybe let them listen to it at the parts store, and they can determine if it's a lifter or not. Let me know how you make out.
