How do I know what axle gearing I have?
Method 1: Count the number of teeth on the ring gear and the pinion. Divide the number of the ring gear’s teeth by the number of the pinion’s teeth. This will give you the axle ratio.
What do rear end gear numbers mean?
In simple terms, the numbers mean how many turns of the drive shaft to one turn of the rear wheel. If you are cruising down the freeway at 60 MPH with 3.00 gears, in a typical high gear with a 1:1 output ratio, it simply means that the drive shaft (engine) is spinning 3 times for every 1 rotation of your tire.
What gear ratio is best for acceleration?
A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.
Do front and rear axle ratios have to match?
Final drive ratios must be the same. A diff doesn’t have a ratio and is always the same, ie, One wheel stopped, the other side twice the speed. All diffs are the same. Any difference in final drive ratios front to rear will cause failure unless a centre diff is running the DIFFERENCE of speeds.
How do I find out what gear ratio my Ram truck has?
You can always look at the tag on the differential. It has the ratio printed on it. You can also get your build sheet which is specific to your truck and lists all components used to build your truck. Simply plug your Vin number into that link.
What is the gear code on a Toyota 4×4?
This one is from a 1989 Toyota 4X4. The gear code is circle in red and is G292, which indicates an 8″ rear diff with 4.10 gears and a 2 pinion carrier. Above is a typcial earlier model Toyota VIN plate, located on the engine compartment fire wall. This is from a 1986 Toyota 4X2 truck.
Where is the Axle code on a Toyota?
The axle code is on the driver side door jam for those who don’t know and I bet most will start with a “B”. Any one else with a 7.5″ ring gear. I just find it odd on a V-6 auto. A04C whatever that means.. A04C whatever that means..
What is the gear ratio on a Toyota?
The second and third digit, both numbers “29” refer to the gear ratio. In this case, the gear ratio is 4.10. The fourth and final digit, “2” denotes the number of pinions of the rear diff and whether the rear diff is an open or LSD type.
What is the Axle code on a Toyota 4Runner?
The first position of the Axle Code is a letter which identifies the diameter of the ring gear. Toyota trucks and 4Runners have always used the 7.5″ and 8″ diameters, but the others are listed here for completeness.
