General situation: Almost systematically, after about 40 min of driving at higher speed, car starts whining at speeds ranging from 45 mph to about 60 mph. The noise appears ONLY when my steering wheel is straight, or slightly turned turned to the right (say pointing at 1 o’clock).
Whining: first it slowly progresses from a timid whining, to eventually a whining that can be felt through the steering wheel.The whining is close to the frequency of the note F (about 700hz) , and seems to be coming almost from the steering wheel, or the engine bay. PLUS (…) when I let go of the gas, whining continues, but when I touch the breaks, whining stops immediately.
Condition of car: the car is obviously older, has around 120k miles, all fluids changed just past month. Everything is running fine otherwise.
I’ve been trying to figure out what the problem is but haven’t had much luck, so I’m trying my luck here. I tried to be as specific as possible but if I have left something out, def please ask, and if you could help me diagnose what the issue is, please let me know.
