The supposedly “best” rear end, Ferd 9 inch uses a green style bearing and it’s used from daily driving to pro-touring to auto cross. So why is it when the same style of bearing is used in a Mopar, they can’t take the side loading?
Ford 9’s have used several different bearing styles over the years. Let's see, most popular seems to be the Timken Set 20, heeeeeey, wait a minute! That's a tapered bearing!
"This is the superior design that came stock on 1979-86 Bronco's and F150's. It is a tapered roller bearing that will work on the 1978 and prior Ford 9" 31 and 35 Spline axles.
- Single-row bearings can accommodate radial load and axial load in one direction.
- This type of bearing is suitable for use under heavy load or impact load.
- Bearings are classified into standard, intermediate and steep types, in accordance with their contact angle.
- The larger the contact angle is, the greater the bearing resistance to axial load.
