My 2005 4.0 pony has 165,000 miles on it. I recently had a seal on the right rear start leaking and had them both replaced. Now, about 2 months later, the rear end has started a whining noise. when I am coasting there is no noise, only under acceleration.

Could it be the wheel bearings making the noise or is it more likely to be the differential?

Thanks!

    I had both (right and left ) rear axle seals replaced and the lube that went in it was 75w140 synthetic gear lube.

    Thanks!
