Cherokee Classic 1999 making whining noise in back

Hi there,

I have a 1999 Cherokee Classic, when I have drive at low speeds 10 - 40mph a low whining can be heard from the back of the car. When on the freeway it is less noticable. Do I need to change my differential. Any help would be great

Many thanks,
Miro

I would pull the cover and give the gears a look. Check the fluid for excessive metal particles, and if all looks good refill with new fluid and see if the sound is still present. It could be a bad bearing, low fluid, worn gears, it's hard to say without a visual examination.

Might be dumb to mention....but could it be the sound of your fuel pump? I know mine makes noise I can hear at idle (but then again I am without carpet in the jeep).

Thanks guys, I don't think it's the fuel pump, when I'm idle, there is no noise, when I drive from 5 to 40 mph you can hear the noise. BTW, how much would a grear box run me.

Thanks

Hey ThaKingXJ,

How have you dealt with it? What have you found out?
