Hey everyone. New to the forums. I have been searching for a good BMW forum for a while now. Hope you can give me some advice on my problem. I have this really annoying whine sound from my X5 when I rev the engine and when I am driving at slow speeds. Can't really hear it when driving fast. My ps pump was going bad because it made noise when turning the wheel, whine in park etc... I ordered a new $1200 power steering pump
, and reservoir from FCP Euro, and installed it yesterday. I replaced all of the pullies, tensioner, and belt as well.
I drained the fluid out at the rack. Before I installed the power steering pulley, I manually cranked the pump with a little screwdriver in one of the bolt holes to bleed the system a little and get fluid to the pump before starting. I turned the wheel from lock to lock while on jack stands 20-30 times at least while avoiding lock for more than a second. After I didn't see any more bubbles I lowered the vehicle.
The steering feels a lot better and when turning the wheel there is no more noise like before but I can't get rid of this freaking whine for the life of me
I put a mechanics stethoscope on the alternator and ac compressor and didn't hear anything really from those prior to getting the steering pump.
Any suggestions? I have no clue at this point. Here are two videos. One inside the vehicle with the door opened, and one of the engine revving.
Is the new pump bad? Any help or advice would be appreciated.
