J20 front axle question

[Phils67]

For those that don't already know, I am building J20 diffs for my Gladiator. 2 questions.
First, does anyone know the part number for the debris shields on the inner axle shaft? I have googled all night and can't seem to come up with anything.
Second, does anyone know the thread pitch of the upper ball joint sleeves? One of the threads is slightly boogered on the "C" and I want to chase it before I install the new ones. I have the socket for them but the one on the driver side tube is being difficult and it will only be worse to remove it in the future if I don't address it now. They were a b!tch to remove the old ones. Passenger side threads in by hand. Driver side goes about 3 threads and gets really tight to turn.
Any advise is much appreciated!

Take a look around this site if you haven't already.

I got a lot of parts from them, they have good tech/install info too. I have an idea of what you're looking for, but not positive.
I assume the ball joint sleeves came with the ball joints? Contacting the ball joint supplier might be the easiest way. I'm sure it's on the internet somewhere, but I know how difficult it can be to track some of this specific stuff down.

Sleeves came with the joints, they are genuine Spicer. The sleeves aren't the issue, its the area they thread into. I emailed Spicer. Hopefully they respond. I will check that link tonight when I have time, lunch break is almost over.

That sleeve is, I believe, the preload adjustment sleeve. I should be a straight thread without any taper. I couldn't tell you the size or thread pitch though.

You have a dial vernier caliper? Measure the diameter and the length of some threads.

What year is the axle? My book shows a 8128285 axle retainer for '74-77. Presume this is what you mean by dust shield. It may only be available with the shaft assembly for later years.

By dust shield I am referring to the metal ring that is pressed onto the inner shaft just behind the yoke that prevents debris from entering the axle tubes. I have them for the stub shafts but can not find them for the inner ones.

Yes, 8128285. Shows in the parts book.

That number crosses to Spicer number 36364, which I already have here and are for the outer stubs. They will not fit the inners unfortunately.

This is from the '74-80 book. 9.368-1 is the complete shaft assembly. 9.368-9 only applies to the 80-90 models (CJs) so that's for a 30. Looks like you have to buy the shaft assembly to get the part you want, if you bought it from Jeep in the day. The shaft listing says "includes inner slinger and universal joint."

[Phils67]

That sucks. I just bought the shafts and they didn't come with them

FYI if anyone is interested, I established that the upper ball joint sleeve thread pitch is 1 1/8-12. I ordered a tap that size online last night. When it arrives I will update this post.

Its good info to have

Exactly. You can not achieve proper torque with damaged threads.

The tap arrived today and all I have to say is it is a 5 1/2" long thread cutting behemoth but it IS the correct size and pitch for the upper ball joint sleeves on Dana 44 and GM 10 bolts and repaired the threads beautifully. The sleeves thread effortlessly now so tonight the knuckles are getting torqued and then I can start getting parts to wrap up this front diff build.

[derf]

How much was the tap and where did you get it?

[Stuka]

Good to hear. Do you have a part number for the tool?

[Phils67]

Drillandcutters.com part number DWTP1-1/8-12 plug tap. It was about 30 to the door.
