The lube chart shows two grease points for the driveshaft. One at midpoint on the torque tube for the center bearing, and one on the clamsh*ll for the universal joint. The questions are; is EP2 grease appropriate, how many shots with a lever gun at each of the two points and how does the front driveshaft bearing get lubed, as I don't see it indicated on the Ford lube chart? Can these points be over greased?

center drive shaft about 1/2 dozen shots, front clam sh*ll there are two theories on that one, first just about the same with ep2 grease, other to which I subscribe is a grease tub filled with 1/2 synthetic grease, 1/2 synthetic doping pumped into the front fitting which in turn not only applies grease to the clamsh*ll but also to the universal joint to which it covers, this mixture is just about consistency of mustard and allows the uni to run thu it with out creating a tunnel and thus lubing the uni. I use a air powered grease gun and do this every 5000 miles

Thank you for the info Alan. I'm still not sure how the front driveshaft bearing is lubed. As I understand the various parts/service manuals I have read, and rebuild videos I have watched, the front bearing is about 8-10" back from the clamsh*ll. So does the lube from the clamsh*ll/u-joint migrate back to the front bearing?

I use John Deere Corn Head Grease in the universal housing, and i know this grease does migrate back to the front driveshaft bearing. I also occasionally remove the speedometer turtle housing from the torque tube which allows visual inspection of grease in that area. If this area appears to lack lube, I pump some JDCHG into that cavity.

you need to look at the parts drawing to get a better understanding of the layout of the front of the torque tube/driveshaft bearings/seals/speedometer gear/ and the universal and then you will understand what I and another have told you. cornhead grease is about the same as my mixture. I also use my mixture in the steering box, heat from the exhaust manifold does not degrade it

This is what the u-joint housing looks like without any grease. I have seen them stuffed full.

Thanks all for your responses. More research on the net resulted in finding a PDF, detailing the front bearing installation procedure, and the article specifically refers to the holes in the thrust washer that are there to allow grease to get from the u-joint area into the front bearing.

The front bearing is liberally lubricated by the oil from the transmission that leaks back. As for the center bearing, be aware that the grease fitting holds the driveshaft center bearing in place. If the fitting must be replaced for any reason, use an identical fitting, and be sure the bearing is, in fact, in the right place.
