Drive Axle - Rear - 8.8" & 9.75" Ring Gear: Description
WARNING:
On vehicles equipped with air suspension, power to air suspension must be shut off before hoisting, jacking or towing. Failure to do so can result in unexpected inflation or deflation of air springs, which can result in shifting of vehicle during servicing.
Rear axle is a hypoid-design ring and pinion gear encased in an integral cast iron axle housing. A one-piece differential case contains a conventional 2-pinion differential assembly.
To signal rear anti-lock brake system operation, rear axles use an exciter ring pressed on differential case behind ring gear, and a sensor mounted in axle housing. A space is provided between ring gear and exciter ring for measuring ring gear runout.
