What Are Some Common Rear Differential Problems in Dodge Vehicles?


Quick Answer

Common rear differential problems in Dodge vehicles include carrier bearing wear, pinion bearing wear, worn or broken spider gears, worn or stuck clutches, and damaged ring and pinion gears. Almost all differential problems in Dodge vehicles are first indicated by noise issuing from the rear differential. In the case of severe damage to the ring and pinion or spider gears, driving the vehicle may become difficult and continued use can lead to catastrophic differential failure.

A crunching or grinding noise when the vehicle turns or starts in motion usually indicates worn clutches in a limited-slip differential, and damaged spider gears in a standard open differential. Both limited-slip clutches and standard open spider gears are within the differential carrier, which is inside the axle housing. A whirring noise on deceleration typically only indicates worn or damaged pinion bearings. A whirring noise on acceleration or over a limited range of speeds indicates worn or damaged ring and pinion gears.

The differential carrier turns on carrier bearings, which can wear out. A whirring or growling noise at speed, especially over 20 miles per hour, indicates worn or loose carrier bearings. If work was recently done on the Dodge rear differential, noise on acceleration may indicate a ring and pinion gear that was poorly set up.
