Hey everybody,

I am new to this forum as of today. And I wanted to know with only 61k miles, I would after 6 months owning my 350, under the chassis I started to hear..whirling like these videos 1.) The next video is the closest description 2.) Pleas, if anyone can help would sincerely appreciate it, thank you in advance!!!

 

Does this happen when you're moving or when the car is still, like in the video? Automatic or manual transmission? Year of vehicle? Mods?

 

Hey Thanks for the reply.

In the video, NOT moving...just sitting there idling, even as if sitting there...revving the motor sound is still there. It is a 5 speed automatic. As normal, start up the car in the morning as usual no problem. Sometimes in the afternoon, I would start up the car, that faint sounding compressor noise comes around...very close to the #2 video. Never really drive it hard or red lined the engine. Just checking the Driveshaft of ALL the bearings connected not from there. not sure at this point. Just had spark plugs, oil changed early over 4 weeks ago, before my smog. That's about it this point, it does not hinder the performance, still drives really nice. Oh by the way, My apologies the #1 video sounds like He he has a 6 speed transmission...fyi

 

Start with the simple things: Check the condition of your ATF and look for play in the exhaust heat shields and check for exhaust leaks at the flanges (or maybe some other type physical damage.) Have a friend lay on the ground next to the car (not under the car) and see if they can determine where exactly the sound is coming from.

 

Great, thanks a bunch..guy! I kind of was thinking Catalytic converter Heat shield rusted of the welds or something. The ATF fluid, not sure if the previous owner changed it but, also so checked this when I did my oil change! Looks normal not Amber in color though. Also I forgot mention....When I installed the 2 Belts a/c and alternator belts...I may tightened it TO TOO TIGHT, maybe this effected the Water pump!! I'l try and ask my friend, has has a garage lift...and go from there, i guess.
Thanks again!
