Now I know that there is going to be a whine but it isn't a constant whine it only occurs at certain speeds is it part of the break in will it quiet after breakin miles or is it always going to be like that?

 

I've had my gears for about 6k miles...the whine seems to be permenant.

 

does it quiet because it is really loud at some constant speeds

 

Mine really sing at about 72-74mph.

 

The 4.57 car I've driven whines the loudest from 3000-4500 RPM at light throttle inputs.

 

Get use to it... it wont go away even after breakin.

 

Mine whine, nothing major, but I am like Slows2k rpm range

 

My 4.57 were loud but my 4.56 gears were near OEM quiet I am putting in a new setup tonight I built with 4.56 gears. I think it's the luck of the draw when it comes to the amount of gear wine you end up with sometimes the rear is quiet with only a slight wine at certain RPM

 

haha i just made a post about my 4.77 whining and everyone said its not normal and in this post everyones saying the complete opposite..i have no clue now

 

Gears from Richmond are cut straighter and are thick, this is why they wine. The 4.56 and the old 4.57 are Richmond gears the 4.77 gears are from KIA and are made for the everyday driver.
