There is a whining, whirring sound coming from drive shaft?

Hi,

Don't laugh, but often I find the rear tires are chopped or worn in a way that causes this type of noise. Check that first. If they are worn evenly, then check the differential fluid to make sure it isn't low.

On the differential, there is a fill plug and a drain plug. Remove the fill plug (see pic 2 below). You want the gear oil to be no more than 1/4" below the bottom of where the drain plug screws into the cover. Also, make sure the oil is clean. It should be a golden-brown color.

If that is in good condition, I attached diagnostics below for you. Take a look through them and let me know if you are comfortable performing them.

Also, see if the sound changes when making turns, and let me know.


Take care,

Joe
