What does front diff mean?
What does front diff mean?
The differential is a set of gears that transmits engine power to the wheels, while allowing them to turn at different speeds on turns. With front-wheel-drive (FWD), the differential is alongside the transmission inside a housing, and the unit is called a transaxle.
How are differentials identified without an ID tag?
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. Dropout differentials are also referred to as 3rd members or pumpkins.
What do the numbers mean on a Dana differential?
The Bill of Material (BOM) number is used to identify Dana differentials. The BOM will identify the model number, the gear ratio, the type of differential, and all component parts. Traditional BOM’s are 6 digits followed by 1 or 2 digits and start with the numbers 60 or 61.
What do the numbers mean on a Ford axle tag?
It will either be a three-digit code with a space between the first digit and the remaining two or, it will be a digit and then a letter ‘L’ followed by two more digits. The ‘L’ indicates the gear ration is of a locked traction type.
Which is the best way to identify a differential?
Differential Identification by Tag Number The most accurate differential identification is provided by the bottom line of the tag number or axle tube stamp. Differential tags can easily be used to identify Dana and Ford differentials. Dana Spicer Differential Tags
Where do I find the rear differential ratio tag?
It is normally located on the side of the rear differential that is closer to the front of the vehicle. This ratio tag will state required gear ratios for the rear differential for your specific vehicle and usually ranges from 2.50:1 up through 4.30:1.
