Bad Transmission or Wheel Barring Problem

A little while ago my car started makeing a funnie squeeking sound comming from the wheels it sounded like. if i went around 20 MPH you could really hear it but if you go faster it goes away. IT ONLY HAPPENS WHEN I TAKE MY FOOT OFF THE GAS AND BEGIN TO SLOW DOWN. I have ignored the sound and now its making a knocking noise with my foot on the pedal, but one again only on once in a while. It cant be my brakes because i just got the fixed too. Could it bee my wheel barrings or my transmission or maby my differencial. Someone Please Help

dont mean to sound bad, but are you hard on your car ? is it a 5-sp ? auto ? because i have some advice if you're hard on it. lol

My three initial suspects (in no particular order) 1) A wheel bearing, 2) if it is a front wheel drive, ('86 or newer) a CV joint, 3) brake calipar is sticking a little and causing the brake pads to rub against the rotor a little too tight.

i mean im a little harsh on the car... but who isnt. Its a 94 toyota Celica with an auto trans. but it seems the problem changed, insted of a squeeky noise when going slow its a clunk noise when im goin about 45 and i give it a little gas. if i let of the gas it stops. 1st 2nd and 3rd if im slowly accelerating are fine its just when im crusing at 45 50. Some One Please Help
