How often should you lubricate the torque tube-diff front gear assy and what type of grease would you use?

I would guess something like bearing grease? As for age or mileage I don't think its mentioned in the service schedules. If you don't know when it was last checked I guess that's a good reason to do it?

Lubricate on assembly with the heaviest stickiest grease you can get.
