Can the gears with less teeth be causing these issues?

    Hello all,

    Recently has to replace spider gears as well as the shaft with bearings. Due to need of use of the jeep i had to replace the gears that had less teeth than original. Original gears have 14 teeth for the large gears and 10 on the smaller ones. I ended up with humming from the rear end and the u joints have broken two times in a span of about six months. My question is, can the gears with less teeth be causing the humming as well as breaking the joints? I'd appreciate any help.
