Front/Rear Ends & Differentials

ANALYZING DIFFERENTIAL FAILURE

The images below are displayed to assist you in making an accurate Analysis of Differential Failure .

Visually inspecting the failed or damaged ring and pinion gears and/or bearings can indicate the cause of the most common failures.

normal-ring-and-pinion-wear

The tooth surface on the ring and pinion apparatuses is just respectably gleaming. The machining striations on the drive surface of the ring gear teeth are still visible (on the genuine rigging set, if not in the joined picture). The face or edge of the pinion equip teeth is still squared off. This ring and pinion set shows ordinary wear.

burned-ring-pinion

On occasion a ring and pinion set has been scorched so that the tooth surface is exceptionally glossy. The machining striations are no more extended unmistakable and there is a hard edge at the foundation of the ring gear teeth demonstrating how much the surface has been scorched off. The face or edge of the pinion adapt teeth is worn to the point of being sharp. Blazing like this is brought on by oil disappointment. There was insufficient oil in the differential, or the differential was not appropriately set up, turned out to be excessively hot, and the oil separated.

very-burned-ring-and-pinion

Some ring and pinion set shows intemperate warmth displacement. Considerably more of the apparatus tooth surface has smoldered off than in the case above. The pinion adapt teeth have exhausted to a sharp edge. Once more, the cause is the oil.

broken-ring-pinion

Sometimes teeth have been sheared off this ring and pinion set. This is clear in the dull hazy areas. The sparkly regions have been pounded by the broken apparatus pieces. This does not demonstrate that the ring and pinion equip set was flawed, but instead that an excess of force was connected with an excessive amount of resistance in the tires. This can be brought about by an excessive amount of force consolidated with larger than usual tires or tires that are stuck on a rough terrain snag. Turning tires that abruptly get either go romping or on the track can break differential parts also.

PITTED BEARING AND RACE

This degree of pitting can be normal for bearings with 100,000 plus miles. This bearing and race would be extremely noisy.  Pitting can also be caused by lots of preload and by limited lubrication failure. Lubrication failure will often cause the roller cage to melt.
