Roar fron the rear end indicates the pinion is not meshing with the crown , most probably bad bearings, disconnect the drive shaft and rock the yoke or turn it slow you will feel the roughness, the only fix is replacement of the rear end

If the sensor is not in the transmission, it could be in the rear differential. The sensors at the wheels and differentials are usually for the abs system.

Rear end on f-350 makes roaring noise. I checked oil level and it was ok. The oil seems to be very thin. Could wrong oil cause rear end noise?


Differential roaring noise is usually caused by a bearing that is worn or has pitting in the bearing race (half of bearing without rollers). A whining noise would be caused by worn ring and pinion gears. the roaring could be from the carrier bearings (two bearings holding the differential case to the axle housing) or fron the pinion bearings. The fluid is typically heavier but will seem thin when hot. The fluid isn't the causing of the noise but if the wrong fluid is in the differntial it could have caused the bearing to go bad which then causes the noise. good luck.

try the cooling fan its controlled by a thermo clutch,check it out.go online they tell you how.or if the fan free wheels to easy it likely is defective.

i'm thinking that your tires need speed balancing :),, if is not the tires then one of your bearings on the hub needs replacing or the exhaust has a hole somewhere.
