Summary

The video follows a car enthusiast as he replaces the broken rear differential on his modified Nissan pickup truck. After searching unsuccessfully for a used Nissan differential, he installs a sturdier Ford Explorer unit. The process involves carefully measuring, welding new mounts, adapting brake lines, and test driving to ensure proper 4x4 operation. Despite challenges sourcing parts and fabricating custom brackets, the upgraded Ford differential is successfully installed, resulting in a more robust drivetrain for the high-powered Nissan.
