In 6th gear at about 85 mph I hear a whinning noise coming from the rear. Is this normal? It almost goes away completely at around 90mph. Im paranoid because I had a rearend on my Ranger lock up on me once.

Change your diff fluid and see if it helps.

 

a little gear whine, nothing serious. You can hear it pretty well in the Z cause there is not much sound deadening material back there. Mine does it too, but its not a problem I dont think.

 

Same here. I always hear some whine on my way to work in the morning. Nothing serious.

 

Is your wife/ girlfriend in the trunk?

 

That was the first thing I thought off when I saw the title.

 

same here. there was a thread about this, and someone had the rear end replaced by the dealer, and the noise was still there. I guess in his situation the noise was from the tranny. I could swear that its coming from the rear of the car though.

 

Hey guys
Have the same noise at about the same Mph.
Take my foot off the accelerator and it disappears, tap the gas and its back.
Anybody ??

 

i have the same exact problem when at 3200rpm and doing 80-85 its a low tone but its gone when i take my foot off the gas

 

Ok well Im not going to worry too much. Seems like its just one of those things that was "included for free".

 

well just maintain your rear-end diff fluid. if you autocross or track frequently or say even drift you should change it whevenver you can, . but if its daily driven with no time about 30k change the fluid. thats advice from some of my friends who track their vehicles.
