I have some rattling sound on my 03 Evo that increases the faster I go almost like a knocking. It sounds like it is coming from the back tires. It seems like a flat tire sounds but the tires are fine. Can anyone help me??

 

your differential might be going bad.

 

From one or both sides?

It maybe a flat spot

 

it seems like one side but when I look at my tires they seem fine. It is really driving me crazy I don't know if I should stop driving the car until I take it to the dealer, I don't want to make it worse.

 

does it make the sound when you make turns and accelerate?

 

it makes the sound when I accelerate it gets a little faster. Sometimes I hear a creaking when I turn but I don't know if its related.

 

Check your lugs.

 

sounds like a flat spot on the tire(s) did you skid to a stop or slide out?

 

dont have anything stuck in the tread like a rock or something?

 

Same thing happened to me. It gets louder and dies out as I go slower. I hope its not my rear diff......I launches last night and I was burning out. I hope it wasn't fwding on me

 

UPDATE: I took my car into mitsubishi and drove it with a tech that has an EVO. He had no idea what it was at first. After taking a look at it underneath he told me he re-torqued something and the sound went away. It wasnt the lug nuts but he said something else and I could understand him ( he has a really thick accent). Anyway the sound is gone now so now I just have to think of the things he could have re-tourqed underneth the rear of the car!
