Will, I responded back to you via Fordbarn pm earlier today. I'll double check to make sure it actually went out.

For info. about torque tube center bearing read this:
https://www.fordbarn.com/forum/showt...center+bearing

Here's what my original 40 Ford center bearing looked like in 2017 when I replaced it. The car was "raked" and banjo oil went into torque tube and dissolved the rubber encasing the bearing. It was just a pile of "goo" with a metal bearing hiding inside. The outside grease fitting does line up with a "lube hole" in the bearing rubber casing.

OEM bearings (3rd photo) are impossible to find and if you do find one be prepared to "
step up" to some high dollars, like several hundred dollar bills.

Installing the OEM bearing requires a special KR Wilson tool. Otherwise, it's extremely difficult to do. Best to go with Skip's bearing. Cheaper and easier to install. Good luck.

Thanks 19Fordy. That's quite the goo pile. Mine wasn't quite that bad, the rubber in the center was ok but the outside 1/4" on both sides was dissoled/dissolving. I'm waiting to receive replacement from Skip. I almost choked on the price after converting from our VERY poor Canadian dollar, I can't imagine OEM bearing pricing...

Would it be wise to install a zerk in the torque tube to lubricate the front roller bearing? Currently there is not one, the closest zerk is in the clam shell. There is one on the attached photo were I'm thinking one should be on my torque tube, I'm assuming the pic is of a hollow drive shaft given the width(taken from VP website).

Pack the bearing and install as is or install zerk?

It should get enough lubricant from the U-joint cavity overflow. Ford had it designed that way so they didn't put a zerk in most I've seen. I'm not sure how easy it would be to put one in the average Ford torque tube. The bearing and outer race take up a lot of the room in there. The grease fitting would have to be pretty shallow in the depth it protrudes if one is installed. The speedometer drive is also mounted pretty close there. It can be removed if someone wants to put some lube in there.

Thanks rotorwrench. I'll leave as is.

The good ol waiting game now...all parts, pieces, gaskets and seals in mail and enroute. Can't wait to get this thing back together!

So..... I've got the differential back together. New seals, carrier bearings/races and new to me, used axles. I reused the pinion, ring gear and pinion bearings/race as they were in great shape. Was quite the task but with the help of a couple resources I found online, vern tardels book and numerous threads/forums from the fabulous folks on the ford barn and hamb it's together and waiting for paint to cure/harden before finally assembly of torque tube, spring and finally into the car. I ended up purchasing a 12ton hydraulic press(luckily on sale) which made the job so much easier and cost effective.

Upon further inspection I decided to replace the spring shackles. To say this job is a PITA is an understatement! The ones in the spring came out with the hydraulic press no problem. But the ones in the axle housing were a different story. I made a hand press with some scraps I had kickin' around which helped for the left side but not so much the right. After hammering out the bolt, the hand press pushed out the metal sleeve with ease. However, the right side not so much. It would not budge! I ended up using the hacksaw method to cut into it, once I was thru enough I wedged in a screw driver to curl the sleeve enough to put in some penetrating fluid. I was then able to press it out. The handle on the press pictured is really of no use, was on the threaded rod already, I just used a long wrench over the stub for leverage.

Can't wait for final assembly and installation! At least I still have some summer left to hit the road!

Pretty excited to test the results of my transverse leaf spring lubrication experiment. Due to location and current covid situation I was not able to acquire any "slip plate" and am not a big fan of the Teflon strips for my leaf spring. The only dry lubricant available is an airosolized graphite, thinking it wouldn't last long I decided to get creative and try something different.

I mixed 26grams dry flake graphite powder with 625ml tremclad oil based gloss paint. I made a mini paint mixing tool for my drill and very slowly added the graphite while mixing the paint.

All the leaves were separated and taken down to bare metal. After applying an etching primer I applied the first coat of pre mixed graphite/paint. After allowed to dry and cure a second coat was applied. This time before paint was allowed to dry I shook 6.5g of dry flake graphite evenly over each leaf. This was done to both sides of each leaf(except bottom of last leaf and top of first leaf). Once the leaves cured and hardened they were assembled and sprayed as a whole with the same paint but without the graphite.

Will keep you posted as to the final results.

After second coat of paint/ graphite mix and dusted with flake graphite.

New spring shackles finally arrived, no thanks to Canadian customs who held them for over a week. Between multiple other projects and the honey do list, I managed to get it all assembled today. Tomorrow I can instal it into the car If all goes well new rubber going on early in the week, get insurance and on the road by next weekend.

Will, this has been quite a project for you!!! Nice job from the looks of your pictures.
I went through a similar process with my '39 and because I didn't have a shop press, made a great connection with a machine shop and machinist! Your description of the spring perch removal brought back old "memories" !!

Best of luck!!

What direction did you install the front driveshaft seal ? Some have installed these backwards .

Great looking rear axle. I still have to tackle that job. Be sure to install an anti-squeak pad for the rear spring, between the spring and the crossmember.

1. Driveshaft seal: Sharp edge/open spring side facing U joint.
2. Inner axle seals: Sharp edge/ open spring side facing differential.
3. Drum brake seal: Sharp edge/ open spring side facing toward roller bearing.

Thank you Zeke3. I did install an anti-squeak pad between the spring and crossmember.

Got it all bolted back in and new brake cables installed. Tomorrow after work I can adjust the brakes and put the floor back together in the cab. A guy could really use 3 other hands to install the clam shell....

The driveshaft and u joint lined up well. I had the diff sitting on a 4 wheel dolly with a just enough clearance between the spring and cross member. One i got it aligned and started from the top side I was able to hold onto the rear bumper, with my feet on either side of the diff on the axle housings it pushed right on/together.

One more step closer

Road test went Great! no issues, funny noises or leaks. I managed to get off work early today and get insurance. Put on 80 miles and had a blast! Sure missed driving er. Just about got a deer on the way home, thank God he didn't stop, just trotted right across. Sure made my heart jump

Thank you to everyone who helped with direction, advice and parts! Sure wouldn't have got her back together without all the great help on the Ford Barn
