How's that for a catchy article title? I was debating on using that or "Be sure to lube your rear end" and decided to stick with the former rather than the latter. In this case, we'll stick to discussing your vehicle rear end. What you do with yours is your business.
The rear end of rear wheel drive vehicles and four wheel drive vehicles has an assembly called a differential. The differential is designed to allow the power from the engine to be transferred through the rear wheels. The driveshaft goes straight back into the differential and the rear wheel axles come in from the sides. The housing is filled with a special gear oil.
