Your 2000 Chevy Silverado uses sae 75w-140 differential fluid in the front. The differential is a part of Your vehicle that compensates for the difference between the inner wheel and the outer wheels travel when You turn a corner. It is recommended that the differential fluid be changed every 30,000 to 60,000 miles. It is a messy job and should be done by a licensed mechanic. Getting the old fluid out of Your car can ensure it runs smoother and prevents any damage to the gears. If the gear oil runs low or becomes excessively d***y, it can cause the gears to whine or howl as they turn.
