Look for weird wear paterns.  I've had in the past strange noises from
the wheel wells and found out it was 'cupped' tires or tires were
rubbing because of an out of aligned wheel.

Its hard to say without hearing the sound. Might be nice to post a .wav or .mp3 file with it. It could be anything.

On stairing right U had no sounds. At the moment, left front and rear wheel have allot of presure on it. Going sraight less. And the more you stair left, the les presser on it.

My gues would be, on left front or rear wheel:
- Barings (Front U did, maybe need 2 check the rear one aswell)
- Suspension left side : Could be that an assembly point needs tightning, rubbers and bushes (if I wrote that correctly :+ ) could be worn out.
- Last point could be is a bearing of the stearing wheel. This however would mean you feel some fibrations trough the stearing wheel.

Also test a few things:
- While accelerating a bit in a corner (not 2 much, U dont need 2 crash :-) )
- While braking a bit in a corner (not 2 much, U dont need 2 crash :-) )
- On a straight (empty) road, do a little slalom (left right left right a few times)

Hear and look if there are some fibrations around, if the sound changes with one of these possiblities, and if you can hear where it comes from (open your windows wenn trying, and put a passanger in the car. tell where U hear it. Let them tell where they here it.
We where figuraing out where sound came from for 1 month. Then I became passanger. He thought it came from the left, I also heared it left. After looking further, we found that in the roof of the car, there was a small box, with sunglasses in it. The sunglasses where the cause :-)
So look for stuff like that aswell :-)
