Sorry if I'm keeping on about rear axle rebuild. Now have the pinion assembly installed in the banjo. That was fun. Some say the preload torque should be 12-15 inch lbs to turn the pinion. Others say adjust to no play, slight drag when turning pinion. I don't have a torque wrench that goes down that low.... is it that critical? Mike

Don't apologize, questions are the reason for this forum! Pinion preload is most accurately obtained by the following method: Clamp the pinion shaft down in a large bench vise, take the banjo in both hands, spin as fast as you can. The preload will be correct when the banjo will make no more than one complete revolution after you release it.

Mike, I can't take credit for that tip. There actually is a KRW spring loaded indicator, however, new bearings aren't friendly to that type of indicator, as the indicator pointer will bounce erratically. The spin method I described has been used by Ford mechanics and rebuilders going back to the day.

The axle seal that's way down the tube near the wheel bearing. The rubber part of the seal is tapered to a sharp edge on one side not so much of a taper on the other side, but still a sharp edge.... witch way to install it? Same seal listed as drive shaft seal for torque tube, which way does it install.

Mike, all such seals having a directional lip install pointed toward the source of fluid, away from the dry side.
