hello everyone.i have a 06 f150 with a 9.75" rear end with 3.73 gears and limited slip. lately there has been a real bad whine coming from the rear end and imnot sure what it is. i dont hav te money to mess aroso i need to figure it out and fix it using as little money as possible. heres some additional info: there is no up, down or sideways movement to the driveshaft. its no the axl beaings. i replaced those already. here is link to the video i made inside the truck. just listen for the whine over my exhaut. thanks ahead of time everyone.

If it has enough oil in it, does it have the limited slip additive in there too? Just asking for something simple. May want to add it if not.

Attyates

yes I checked that. and when I changed it I did make sure to add fords friction modifier
