take a stab.

when going at low speeds, (10-15 mph), i hear howling occaisionally if i turn left/right at sharp angles (more than 1 steering wheel turn).

guess what it is! My guess is a CV boot!

 

I think its probably the "low blinker fl00id buzzer". It has a moaning, howling sound to it because its resonated by the resonator on the reservior. See, what happens is when you turn around sharp turns, the fl00id moves to one side of the reservior, which tricks the sensor into thinking the level is low. Then when you get back in a straight line, the fl00id is spread out evenly and the sensor thinks its full and stops buzzing.

 

Raise your tire pressure.

 

is it coming slower than 10-15mph. Possibly wen like turning out of a parking space or turning left at sharp angles and giving it a little gas?
