★ Top Answer
The 2002 Chevrolet Tahoe needs to have 75W-90 gear oil in the rear differential and 80W-90 in the front differential; these oils are not interchangeable. It's crucial to avoid using gear oil with a limited slip additive to prevent potential leaks. While it may seem like a small detail, the specific gear oil and additives you use are essential. Using the wrong type can increase friction, reduce efficiency, and result in significant damage to your differentials. It's best to invest in the recommended differential fluid, even if it's a bit more expensive.
