Solid Axle Swap BS Thread

When installing my axle shaft and long fields, do I need the compression c clip? I've heard both ways but don't want to blow anything up...

Edit: Running it, I'll try and find another for the other side since I broke that one coming out of the donor axle.

 

What's the argument for not running it? When you go to pull the shaft and birf out the birf would just slide off the shaft and you'd be left with like 2" of shaft to try and grab to pull out.

 

What I came up with.

For not running it:
1. Not necessary (not sure about this...)
2. I already have a locker, so the axle shafts won't slip into the diff too far. (Only half the reason to run them anyways.)
3. If axle shaft breaks off inside birf it's hard to get out

For running it:
Stops the axle shaft from migrating too far into the birf causing failure

 

I doubt you'll ever break the shaft, the birf or the gearset is always what blows up. I don't think the shaft can slide too far in the birf. The birfs blows up when they are put in a bind at too much steering angle.

 

If the axle shaft can't slide too far into the birf I dont really see the point in running it. If I can find one locally though I'll run it anyways.

 

Just thought of something. The axle shaft has a smooth place the the axle seal seals on. With the clip installed the shaft won't float around allowing the seal to ride in the same location on the sealing surface

 

You have to run that clip, it prevents the shaft from binding and the inner shaft from stripping out. The clip thats optional is out by the hub.

edit: I think the optional C-Clip is only if you martack?

 

So many opinions over on pirate... so much "I've done this and it worked..."

For me:
1. Air Locker prevents axle shaft from going too far into the differential (I tried this without the Longfields to check, and the axle shaft stops before the splines reach the sealing surface)
So, martacking seems pointless to me.

2. My axle shafts do NOT have two places for c clips. They only have the one the diagram above shows as optional. I installed the short side last night and will try to find the "optional" c-clip for the longer side. (See above picture for reference, post #6949 in this thread.)

3. I am planning on running the c-clips holding the Longfields out against the brass bushings.


So I will be running all c-clips that are available to me on my setup ymmv.

 

this makes 2 trips to Moab without breaking a single part.

 

well that comment was the kiss of death

 

time for upgrades anyways lol.

 

Getting close to being done with the truck and will be getting drive shafts made here pretty soon. Whats everyone using for the rear? A one piece or 2 piece? And whose using a slip yoke on the front?

 

Personally I'd run two piece and the slip yoke at the axle end. Better ground clearance over a one piece.

 

I agree about the ground clearence but have heard of people having some bad vibrations with the two piece so curious to hear what others are. Trucks still my dd for the most part so want it to be comftorable to drive.

 

I have a 2 piece in my 01 double cab and have no vibrations.I am solid axle and use a long spline front driveshaft and all works well.

 

Two piece in the rear. Jess at hi angle driveline talked me out of a one piece when i did my crawler. No highway vibes either. I never even kissed the driveshaft until i swapped in the 80 axle and it was no longer protected by the gas tank. Now its dented to hell.

Stay 2 piece.

What do you mean by "slip yoke in the front"?

 

Sorry, not a slip yoke. A long spline set up for the front.

Did you guys have anything special done to the 2 piece?

 

The only thing special was i got the first (closest to the tcase) shaft shortened locally for the crawler, that's it. I'm going to need to get the rear part re-tubed and straightened now but that's more from the 80 axle and losing the protection from the gas tank. If you are really worried, i would get the carrier bearing to axle shaft re tubed at a local shop with some thicker tubeing and run the two piece, and go buy a bunch of beer and tanks of gas with the money left over.

If you have a rear shackle setup up front, you will need a long travel/slip front shaft.

 

I'm running a TG long slip in the front and it works great. For the rear I'm running a .250 wall DOM 1 piece shaft with ridiculous joint angles lol
