srange noise

[Tomy]

Hi,

From several weeks I heare strange noises from rear of the car
(sometimes I think it is from front, but it could be my imagination)
This noice come on 40 mph and is going to be loder with spped.
What is strange that if I turn left (long corner or short corner) noise disappeared, If I turn right it is still with me ,could it be wheel bearings? all wheel are cold after driving, this noise going to be to loud to accept.So I need advice
