DIFFERENTIAL TECH TIPS
EL TATE:
5 cut gears, traditional gears, have a taper to the ring gear teeth and a wider spiral. this can create some "slapping" effect and generate unwanted gear noise in some applications like SUV's and unibody gen 3 Camaros for example. The outside edge of the ring gear is considered the "heel" and the inside edge the toe. Imagine standing on the ring gear with your toes in the center. A 5 cut tooth is higher at the heal than it is at the toe.
The 2 cut gears have a tighter spiral to them, use a much tighter backlash setting, like .003-.006 vs .006-.010thou on the 5 cut, and have teeth that are the same height from the outside edge of the gear, (heel) to the inside edge of the gear, (toe). they are inherently more quiet, and ideal for burbans, and tahoes, and expeditions etc, but much more difficult to get good patterns on. Most techs that have been doing gears for 30 years will have no clue how to set them up correctly and will chase their tails all day.
I'll be 35 in November, and the camera hides a lot of gray, lol.
