Many problems with the rear differential of the 2000 Chevy Silverado typically involve worn pinion gears or seals, leading to grinding noises and reduced axle performance. When a new GM rear differential and axles are put in, they can reach very high temperatures while hauling loads during the initial 500 miles, potentially breaking down the gear oil. It is recommended by the manufacturer to change the differential oil with 75W-90 full synthetic after the first 500 miles to mitigate these issues. Once this initial break-in period is completed, the service interval can be extended to every 40,000-50,000 miles, and the axles should not put as much strain on the gear oil. Replacement of the pinion gear seal is estimated to cost between $240-$400, while changing out the gears can run upwards of $1,500 in total for parts and labor.

If you hear noises coming from the rear end or rear differential of your 2000 Chevy Silverado, it's probably because the gears have worn out from being overloaded and a lack of proper lubrication.
