What is a ring gear in a differential?
The ring gear of the rear axle surrounds the housing of a differential gear train that serves as an equalizer in dividing the torque between the two driving wheels while permitting one to turn faster than the other when rounding corners.
What do the numbers on the ring gear mean?
The calculation uses the number of teeth in the ring gear and divides it by the number of teeth in the pinion gear to provide you with a “[result] to 1” ratio. For example, if the pinion gear has 41 teeth, and the ring gear has 11 teeth, the ratio would be calculated as 41/11, which is equal to 3.73 = 3.73:1.
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 can I tell what 10-bolt rear end I have?
The easiest way to identify the 8.2-inch rearend at a glance is by the shape of the housing and the spacing between the lower bolts on the cover. The 8.2-inch 10-bolt has a smooth, round, lower-case area (no cast-in protrusions), with an 11-inch cover that has a diagonal protrusion at the top.
What kind of gearing does a Toyota 4 cylinder have?
Most Toys sold in the US have 4.10 axle gearing, but this isn’t always the case. Four cylinder models with auto trannies often have 4.30 gearing, (4.87 if they came factory-equipped with 31″ tires). All V6’s with 31″ tires and 4-cylinder manuals with 31″ tires usually had 4.56 gears.
What kind of gears does a Toyota 4Runner have?
4 cylinder and V6 gears are the most common gears out there for older Toyotas. 4 cylinder Toyota gears (27 spline) are found in all pre-1995 Toyota pickups and 4Runners in the front and rear.
What kind of differential does a Toyota truck have?
It is a 4-pinion design, whereas the regular 8″ is a 2-pinion design. Many V6’s had 2-pinion cases too. The 7.5″ differential is used in the front of IFS trucks (’86 and later). It is also used as the rear differential on some 2WD trucks. The 8-inch Toyota axles are strong and utilize a third-member setup, much like the 9-inch Ford.
What kind of gears does a Toyota Yukon have?
This is due to larger carrier bearings and a larger diameter pinion shaft. However, the ring and pinion won’t fit into an earlier diff and the differential itself won’t fit into an earlier axle housing. Yukon Gears are higher end Toyota ring and pinions made of 8620 dual heat-treated alloy.
