★ Top Answer
The front differential of the 2004 Chevy TrailBlazer requires 75W-90 gear oil. Additionally, it is advisable to use an additive specifically designed for TBSS differentials. It is crucial to ensure that your differential is properly filled as it provides essential protection for your gears. The differential is responsible for distributing power to the front wheels, following its transfer from the transfer case. Should any gear become damaged, the ability to engage four-wheel drive will be lost, necessitating replacement. The confined space of the differential means that the power passing through it can generate significant heat. Using a thick oil like 75W-90 is recommended as it breaks down at a slower rate compared to thinner oils, providing better heat resistance.
