Ok, so out of nowhere my car starts making this wiiierd high pitich noise....not like a grind. It was coming and going when it pleases, but now it is constant 24/7. It sounds like when an airplane puts its landing gear up (that really high pitch noise like weeeeeeeeeeeeeeeeeeeeee) It sounds like its coming from my rear end.... I searched forever and only found that some people experienced a "grinding" noise after they changed the rear diff fluid, but I changed mine about 3000 miles ago and it just started about 300 miles ago. Does anyone have any suggestions on what it might be??? Thanks in advance for all help.

 

anyone???

 

transfer case???

 

it doesn't quite sound as loud as the "death whine" and it doesn't get louder in higher rpm's or anything n the highway....but it could still be the t-case i suppose eh?

 

most likely the transfer case

 

i had the same problem start yesterday. It get loader with speed. its not the engine car its not rpm related. it started all of the sudden. i changed the center diff fluid and it did nothing. the faster i go the louder it gets,

check your exhaust hangers to make sure they aren't stretching and the exhaust lying on the support bars underneath the car, I had this problem before, just a suggestion

 

i think the noise is coming from the center diff. what would the exhaust be hitting? or why would the exhaust make thatt noise?

 

oh sorry I was talking about the first guy, but do you have an aftermarket exhaust? I'm talking about the tie-bar that sits underneath the downpipe

 

maybe from fuel pump?
My car makes those kinna high pitch noise after I installed welbo..

 

but not everytime tho..

 

it's the start of the deathwhine..save ur t-case before it's too late

 

from your description i would guess that it is your fuel pump, you have a walbro and thats the sound that mine makes...

 

hmm come to think of it the noise did start just a lil while after the walbro was installed, I'll probably change it back to stock just to see if it goes away....hopefully that's all it is and not my transfer case, thanks for the help guys
