Hi,

I just picked up a 2014 S with 35k miles. After driving it home from the dealer I have noticed a distinct howling noise coming from the rear when accelerating.

When I let off the gas the noise goes away and seems to be at any speed.
I didn't notice this when I test drove it in the city.

My explorer did this as well but they were known for bad rear differential.
Is this normal for the Xterra ?

Thanks

2x or 4x?

Second gen rear ends are known to have issues that require replacing the whole axle.

It's a 4X
