6" lift. 3/4 ton axles.
So a few updates

1. Transmission
Got a new deep derale pan installed as well as the temp sender for the trans gauge plumbed in as well. Also filled her back up. No leaks yet.

2. NP241
Installed and filled up.
No leaks yet.
Rear driveline installed

3. Front driveshaft
Dropped off the pinion side of the shaft at a machine shop next door to my work today. Gonna have them machine the part done to slip tightly inside the square tube. I figure some plug welds and a full weld around the face will be sufficient. Hoping to get that back tomoro.

4.only thing left I'd like to do before wheeling this weekend outside of driveshaft

Change bailing twine steps to chain versions
Reeled exhaust mount
Swap plug wires
 
I'm so cool, my truck does 90 without the gauge in!

got the speedo back from auto meter. Not bad. I think maybe 2 weeks from day I shipped it out, and most of that was the return shipping cuz they send it ground.

Got the pinion end of the driveshaft back!
Had it machined down to fit in the tube

You can see the vertical groove they made to have a right tight slip fit even with the inner seam.

Tonight I should have the shaft finished
 
Ill try to grab some pictures later. Shaft is all put together and happy.
Went to put in it and ... ****!

The new derale trans pan I just put on has the temp sender right where the driveshaft lives. First time it turns its gonna rip it out. And since the pan is full I don't wanna pull the temp sender out.

So I'm going to have to drain trans again, take out temp sender and plug the port. ****beans. On the other hand it looks like the shaft is exactly the length needed. Ill have 7" of extension and 7" of compression from static height.

Just a couple of pictures from yesterday.

You can see the sender (gold piece coming out sideways) and how it interferes in relation to where the driveshaft flange lives.

Extended and collapsed. Now ill admit a mistake.
Just kidding. I never make mistakes



When I ordered the tubes,I didn't pay close enough attention and got 3/16 on both pieces. Ideally you'd get 1/4" thickness cuz it will leave a very tight fit. Luckily for me I didn't since I also forgot to get seamless on the outside tube so it wouldn't have fit anyway.
All I did was add some weld material to the corners of the inner tube to take up some slack. We will see how it works out.
 
I did the exact same thing on my tranny pan. Put the sender on the passenger side without even thinking. So now I have a passenger side drain plug, and driverside sending unit, and they both leak. :rolleyes: :haha:

that's why I got a pan with them installed bcuz the last pan where I added one of those plug kits leaked. well wouldn't you know it. LOL should've just kept the factory and added in another leaker and kept the damn money!
oh well. wont happen next time!
 
Shaft looks good.

You are saying the weld seam on the tube is whats making it a snug fit?

I have a feeling that's gonna wear pretty quick, plus its only on one side of the tube so its going to offset just that little much :dunno:


Only way to know is to try it though. Unless your going really fast, I bet it will be fine.

No. I'm saying I added more weld to the four outside corners of the inside tube. Same idea tho
 
Gotchya. Idk if its enough to offset it to bother or not.

Could always grind a little v on the outside of the inner if it was.


Waiting for trail report :thumb::popcorn:

It's not enough that I'm worried about. Ill have much worse issues to worry about I'm sure.

Removed pan. Plugged port. Added port in other side.
Replaced pan

Installed driveshaft.
Tomorrow ill add the fluid back in and hope she no leaky.

The picture is hard to get but that shows how close the shaft gets to the pan. Hopefully we don't get any contact there.
