3. Side Cover Seals: These seals seal the gaps between the differential cover and the housing, preventing the fluid from leaking out and protecting the internal components from dust and debris.

Installation of the seals is relatively straightforward, but it is crucial to follow the correct procedure to ensure proper alignment, sealing, and lubrication. The kit may also include installation instructions, but it is essential to consult the vehicle's service manual or consult a professional technician for guidance if needed.
