Does VIN number tell gear ratio?
The vehicle identification number (VIN) is a 17-digit code that is used to identify and track every automobile produced. … The codes on that tag will tell you the gear ratio. The VIN will not give you gear ratios in most cases.
How do you find the gear ratio on a GM rear end?
Count the teeth on the small gear in the forward part of the axle housing, called the pinion gear. Count the number of the teeth in the big ring gear attached to the differential. Divide the number of teeth on the pinion into the number of teeth on the ring gear. This is the gear ratio.
How do I know if I have a limited slip differential?
The easiest way to tell if you have an open differential is to jack up the car and spin one of the rear tires. If the other wheel spins in the opposite direction, you have an open differential. If it spins in the same direction, you have a limited slip differential, or LSD.
How do I identify my GM rear differential?
The rear cover’s shape and the number of bolts are identifying features for GM rear differentials.

How do I identify my differential?
Without an ID tag, differentials are identified by the number of cover bolts, the distinctive shape of the cover, the number of ring gear bolts, and ring gear diameter. They can also be identified by whether the center section is an integral or dropout design.
What type of fluid goes in the rear differential?
Every front or rear axle is filled with a special oil (also called differential fluid, or gear oil) that takes care of this. The differential fluid lubricates the gears, bearings and other internal parts, and provides cooling to these components as well.
What are the different types of differential?
Different typesAn open differential (OD) is the most common type. … A limited slip differential (LSD) overcomes this problem. … A locking differential (locker) is able to lock the two drive wheels on an axle together. … A spool is an open differential in which the axles have been mechanically fastened together.
