High Pitch Whine. Help?

High Pitch Whine. Help?
Just noticed a very high pitched whine coming from the car while driving yesterday, It's through every RPM range, and in every gear, however its most noticeable at 60+MPH. It responds INSTANTLY to throttle response, If I let off the throttle, the whine is gone, if I get back on it, the whine is back. I'm guessing its a belt or pulley but that's my only assumption. I will get a video of the sound within 1-2 hours to post because I know how hard it is to diagnose an issue without actually being there or hearing it.

Haha, I wish, Found out it was noise that was being transmitted already but wasn't being picked up by the rubber bushings in the LCA's. Swapped LCA's for a set with different bushings and the noise has almost completely gone away. Now I just have to get a set of Stock Over axle pipes with resonators to get rid of the tin can sound from the exhaust.

i have the EXACT same issue. do you have the TORSEN 3:73 diff?
its a differential whine. mine was always there when i bought the car but i could easily talk over it or drown it out with music at a low volume. as soon as i installed my lower control arms and panhard bar, the noise became almost unbearable. the harder bushings transferred way more noise. it drives me crazy but I'm still dealing with it. its really bad at 60+mph.
i have not done anything about it..., It was no big deal with all the stock arms on it but now i have poly bushings everywhere and the noise is brutal. i cant take it to the dealer because their fix would be to put the stock stuff back on :/

Glad it made your day and glad my wife doesn't read the forum.

Which endings did you swap for? Poly? I'm still getting some NVH, but thats to be expected with harder nonstock parts lol.

Hmm alright, I've got BMR but with their other kind...the name of the bushings slips my memory atm, still have something that sounds like a harmonic coming from the rear. Also have some insane metal on metal sounds around 3500-4000 RPM now, lifted the car and checked everything under, I see nothing rubbing or hitting and all bolts are tight on the entire undercarriage. I'm at a loss to what the noise could be currently.
