How do i know what kind of rear end i have?

To determine the type of rear end (differential) in your vehicle, you can start by checking the owner's manual, which often specifies the differential type. Another method is to inspect the rear axle for any identification tags or numbers stamped on the housing. Additionally, you can look for the number of bolts on the cover, as certain configurations correspond to specific differential types. Finally, you can also consult with a mechanic or use online forums specific to your vehicle model for detailed guidance.
