Hi i have a 2001 525i and as i'm driving down the road i hear a noise that
sounds like something is spinning and hitting something. it's sounds like a
whoop whopp whopp whoop. The sound becomes very noticeable when i make a
left or right turn. This was happening piror to me changing the 4 pads and
rotors. I'm not exactly sure where to start looking. At times it sounds like
it's coming from the front but I can't tell. Any ideas where to start

You are describing the noises made by a wheel bearing. I would not expect a
wheel bearing to be worn out on that car yet, but it could be.
You have to pull the tires off and look for obvious stuff that is not
supposed to be there. Lift the car and spin the tire and listen for noise.
Hold the tire by the sides and top & bottom and see if it moves. Then take
the tire off and inspect.
This is one of those jobs that if you can't stumble on the cause within a
couple of minutes, you will probably need a service center. I's be taking
this opportunity to form a relationship with a non-dealer service center in
your area. Pull out the Yellow Pages ...
No I get aftermarket tires but they are the same size as recommended in the
cars manual. I am due for 4 new tires as that will be taken care of by the
end of the month. I'll hope that it corrects some of the issue. I will keep
that in mind when I purchase my next 4
