Differential Assembly: Description and Operation

Rear Drive Axle Description and Operation





Getrag Differential

All models have a 7 5/8 inch ring gear. Each ring gear has specific setup dimensions, A1 and A2 values, stamped onto the side area of the gear. The A1 and A2 values are unique to each ring gear/pinion and are determined during the manufacturers gear/pinion noise and vibration setup and testing. The vehicle speed sensor reluctor ring is incorporated into the outside area of the ring gear. The vehicle speed sensor detects the rotational pulses produced by the reluctor ring and send the signal to the Vehicle Control Module (VCM).

The differential assembly is available in three gear ratios. The 3.42 ratio axle is used in all manual transmission applications. The 2.73 ratio axle is standard equipment for automatic transmission applications with an optional 3.15 ratio axle available.
