The Toyota Differential is the rounded part (the "pumpkin"), in the middle of the rear axle of a rear-wheel-drive vehicle that actually performs three different functions. It allows the wheels to revolve at different speeds during turns, provides the final gear reduction and changes the angle of drive 90 degrees. This is what actually allows your wheels to turn in general, since your Toyota's drive shaft is turning in a different direction than your wheels are. Your Toyota's Differential is quite an interesting part with a very important and involved job to do. Your Toyota is made with extremely high quality and durability, so you can expect your Differential to last, even for the life of your Toyota. However, if you should ever need to replace your Differential for some reason, perhaps you just want to install a different one for a change in gearing, make sure you only install equally high quality and durable parts on your Toyota, to preserve those qualities. You chose a Toyota for these same features of quality and durability, in addition to its dependable performance and classic good looks. You do not want to compromise these attributes by installing lesser quality parts on your Toyota. Choose a manufacturer whose focus is also on high quality and long-lasting reliability, to enhance and maximize these qualities. In addition, make sure you select a manufacturer who has experience making parts for Toyotas specifically, to ensure proper fit and function.
