What is the rear end gear ratio for a 1999 ford ranger?

There's no single rear end gear ratio for a 1999 Ford Ranger. The ratio depends on several factors including engine size, transmission type (manual or automatic), cab style (regular, extended, super), and whether it was a 2WD or 4WD model. And even within those categories, Ford offered different options.

To find the gear ratio for *your* specific 1999 Ford Ranger, you need to:

* Check the sticker on the driver's side doorjamb: This often lists the axle ratio. Look for something like "Axle Ratio: 3.73" or similar.

* Look at the vehicle's identification plate (VIN plate): Sometimes, but not always, the axle code is listed here. You'd then need to consult a Ford parts manual or a decoding chart to find the corresponding ratio.

* Check the differential: This is the most definitive way. You'll need to remove the differential cover (requiring some mechanical skill) and count the teeth on the ring gear and pinion gear. The ratio is ring gear teeth divided by pinion gear teeth.

Without knowing the specifics of your 1999 Ford Ranger, it's impossible to give you the correct rear end gear ratio.
