The 7.625-inch ring gear differential in these vans sees heavy loading from the rear-heavy weight distribution. AWD models have additional drivetrain noise sources. Noise typically increases with speed and may change tone under load vs. coast.
Common Symptoms

On the 1990-2005 Chevrolet Astro, aWD-equipped Astros suffer from transfer case issues including encoder motor failure and stretched drive chains. The encoder motor controls the AWD engagement and when it fails, the system may default to 2WD or make grinding noises. Chain stretch causes a noticeable clunk on acceleration from a stop.
Common Symptoms
- AWD not engaging
- Grinding noise from under vehicle
- Clunk on acceleration from stop
- Service 4WD light on
How to Fix
Replace the encoder motor if the AWD is not engaging properly. For chain noise, the transfer case must be opened and the chain replaced. Change transfer case fluid every 30,000 miles with AutoTrak II fluid. Do not use conventional ATF — the Astro AWD system requires the specific NP-233 fluid.
