Replacing the Enclosed Driveshaft Seals and Bushings
Here is he basic procedure: You remove the 4 bolts (standard transmission/ 6 on an automatic transmission) holding the ball housing flange to the transmission, loosen the rear threaded collar nut on the ball housing and slide it back as far as possible on the torque tube. Slide the ball housing back as far as possible and this will expose the U-joint (have a pan under the u-joint area, as there should be oil coming from the ball housing when you slide it back).
Warning! The driveshaft is under tension from the rear springs and is heavy, so before you disconnect the U-joint, be sure to have a jack of some sort under the driveshaft for support.
Once you disconnect the 4 (or 6) bolts holding the U-joint together, the rear yolk will push back into the torque tube and you can drop the driveshaft down. Then the ball housing and threaded collar will slide off the torque tube and you can change the rear ball housing threaded collar nut seal (sandwiched between two steel washers), the tapered gasket in the transmission flange and the shims. There is a procedure for adjusting the ball housing using the shims (without the driveshaft attached). This procedure must be done with the driveshaft lowered. Basically, you install the tapered cork gasket in the forward flange and a few shims (there are 4-bolt and 6-bolt shims in the kit-the 4-bolt is for the manual transmission and the 6-bolt shim is for automatic transmissions ) . Bolt the flange with the tapered cork gasket, shims and ball housing to the transmission and check to see if you can move the tail part of the ball housing. If you can move the tail piece by hand, you need to remove a couple of shims and bolt it up again. When it’s too tight to move by hand, this is the shim setting you want. You just want enough shims to not be able to move the tail piece of the ball housing by hand. Note! Make sure your ball housing doesn’t have any major grooves or dings the outside where the tapered cork gasket and rear collar seal would contact it, as this can cause an oil leak, even with new gaskets. If you do have these issues, you will need to repair or replace the ball housing. Then you reinstall the threaded collar and ball housing (separately) back on the torque tube, slide them all the way back, raise the driveshaft to align with the front u-joint yolk, bolt the U-joint together with new lock plates,
fold the tabs onto the bolt heads, slide the ball housing over the U-joint, bolt the flange to the transmission, slide the rear threaded collar with the new seal in it and tighten it with a large locking pliers until the rear gasket seals against the torque tube. This keeps oil from leaking out of the rear of the ball housing. Then you need to add a pint of gear lube to the fill plug on the rear of the transmission (rear passenger’s side I believe). This is so you don’t run the U-joint dry before the transmission has a chance to send lube to it.
Note! When you have the driveshaft lowered, you need to remove the rear yolk and check for excessive play in the front driveshaft bushing. It should be free from side-to-side play (or VERY little play). If you get a lot of play in the driveshaft, you need to install a torque tube bushing (Filling Station part number V-10*). This is a whole new project but should be addressed when you have the driveshaft lowered.
One more thing you should do while you are performing this procedure is to remove the plug at the differential to see if it is overfilled. If you get a lot of oil coming from the drain plug area (at a normal driving stance with the driveline attached) this is an indication that the seal in the front of the driveline is leaking oil from the ball housing area, down the torque tube, into the differential. The good thing is that the V-10* torque tube bushing corrects not only both front bushings, but puts in a new seal as well, correcting all of the issues with the front of the torque tube. The new seal in the V-10* bushing assembly rides on a part of the driveshaft that has never been used, so you have a new surface for the seal.
Installing a SB V8 in your old Chevy?
Here are some tips from a customer that had to find the correct radiator hoses!
It seems like this should be an easy task, but as my customer found out after numerous trips back and forth to the parts store, it’s NOT a no brainer! Gale Whitley has a 1948 Chevy pickup that he had me do some restoration work on and he found that the seemingly simple task of fitting radiator hoses to the small block V8 engine he installed was not so simple. He spent days researching and making trips to the NAPA store and finally found the hoses that would work for this combination. He said that the hoses he found route nicely but he did have to trim off some of the excess hose.
He asked me to pass on this information to save future restorers the headache of going through this task, so here’s the scoop:
Upper hose: Gates brand #20416
Lower hose: Gates brand #20345
New! 1951-55 1st Series Chevy Pickup Door Restoration videos!
This year I added seven new videos to my channel, specifically dealing with the removal, restoration, and reassembly of the doors for 1951-55 Chevy trucks. If you are planning to tackle this project on your truck, these are must-see videos.
You can see the series on my channel:

1951 – 1955 1st series Chevy Truck Door Assembly Procedure
Starting from a bare door shell:
- Install the door latch
- Install the outside door handle
- Install the window regulator
- There is a rubber strip (scraper) that rubs against the glass when the window rolls up and down. There is a channel inside the outer door skin that this strip slides into. Most times, there is an old brittle strip of rubber in this channel that you have to take out in 1” chunks. There is a space in the middle of this channel that aids in removing these chunks. I use a screwdriver and hammer to chunk it out. Once this is removed, cut the new rubber to length and slide the rubber strip into place. I start in the center, then slide one side in the track and tuck the other side in with a flat blade screwdriver. It is normally fairly loose and floppy in this channel which is OK.
- Install the rear window channel retainer (2 sheet metal screws from the outside rear of the door shell attach this channel and there is one at the top pf the metal retainer that is originally attached, but this is optional in my opinion).
- Install the felt run channel that goes from the rear window channel retainer to the vent window. There is a clip at the bottom of the retainer that the felt channel slips into. Slide the felt channel into the door window opening, then slip the channel into this clip and leave the run channel long and cut it once you have the vent window in place. For now, just let the felt channel hang out of the window opening.
- With the window regulator in the “window closed” position (the roller at the top of its travel) carefully install the door glass (with sash channel attached) onto the window regulator roller, roll the window down and push the glass to the rear of the door and into the felt run channel you previously installed.
- Note! Before you install the vent window, chase the threads in the nut at the bottom of the vent window vertical post and put a little grease in the nut. This will make installing the 5/16-18 hex head bolt much easier later. Don’t try to install a used rusty bolt here, you will hate life! You will see what I mean later.
- Slide the vent window assembly down into the door.
- Once the vent window assembly is in the door, you need to get the door glass into the felt channel of the vent window post and work the vent window assembly into place where it will bolt into the upper door window opening and where the lower post will line up with the bracket down inside the door (this may take some manipulation so be patient). Don’t screw in the upper vent window assembly just yet. You need to get the lower post bolt in place first.
- Now the fun part… You need to install the 5/16-18 x ¾” bolt through the bracket inside the door and into the nut of the vent window post. Access to this is through the lower hinge cover plate opening. You need to locate the bracket in the door (I use a mirror and flashlight in the door) and the vent window post with the nut over the bracket hole. Now you need to thread the bolt into the vent window post. If you are like me, I can’t get my arm with a nut and lock washer far enough into that opening to get this bolt into the vent post nut, so what I do is get a short 9/16” socket and a ratchet extension (maybe 10” or so) that is long enough to get the bolt up to the bracket (no ratchet attached yet) and allow you to get the bolt started. Once you have the bolt started, you are home free. Now you can attach your ratchet to the extension and tighten the bolt.
- Now that you have the lower bolt attached to the vent post, you can screw in the three sheet metal screws along the leading edge of the vent window assembly and the two ¼-20 screws at the bottom of the window opening to secure the vent window in place.
- Now take the felt channel that you left long previously and work it into the upper window opening and over to the vent window to determine the length you need to cut it. After you cut the channel you can work it into place and secure the channel into the window opening with a few #6×3/8” self-drilling Philips Head screws This is the easiest way I have found to secure the channel into place. 4-5 screws in the channel should be enough. https://www.ebay.com/itm/6-Self-Drilling-Sheet-Metal-Screws-TEK-Tap-Pan-Head-Stainless-Steel-All-Sizes/263162027646?var=562159980733&hash=item3d45adde7e:m:mqdbAhukx7AlEY-3ktAcgIQ:sc:USPSFirstClass!97355!US!-1
- Now attach your door handle regulator by first fitting the oblong hole of the long arm to the door latch, then swing it up in place and attach with 3 screws.
- Now make sure all components are working properly, then attach your inner door window trim, door panel, door & window handles and arm rest (if you have one).
I know this all sounds complicated but it actually goes fairly quick once you get this rolling. The second door should take you half the time.
