I have a 742 center section rear axle with a leaking pinion seal.
1. The FSM says to use a special tool to set seal depth when installing a new seal. Do I need it? Is the a shadetree way to get the seal depth right?
2. Will I be able to replace the yoke after the seal replacement without affecting bearing preload?
3. How do you torque the nut holding the yoke properly?

TIA
