4x4 Services Castle Rock
The differential and transfer case fluids keep your drivetrain cool and quiet. Those fluids break down and become gummy over time and numerous heat cycles. A 4x4 service will drain all of the old fluid out of the front differential, rear differential and transfer case and replace it with new, clean fluid. By keeping these fluids fresh, you will keep your 4x4 vehicle ready to tackle any terrain that you throw at it.
