I had the same thing, the pinion gear was bad.
The howling is most likely one of the wheel bearings.
replace wheel bearings
most common is wheel bearings
Need to check left and right front wheel bearings.
If a wheel bearing is bad you will hear a howling noise while your driving.
Probably have problems with the pinion bearings, carrier bearings and or ring and pinion gears inside the rear differential.
Signs of when your car needs new bearings: 1. The bearings are howling, or you may hear a knocking noise as you drive along 2. When your car is on a jack and you pull your tire back and forth and it feels like it shifts a little or is wobbly. 3. When your car is on a jack and you have a hard time spinning the tires. 4. If you take off the hub cap and it looks like all the grease has run out of the bearings.
