Help drivelineman!

Yes please tell us more. How is it supported in the middle? Detailed pics?

The carrier bearing is mounted to the crossmember and I paid $450.00 for the whole shaft.

Why are you running the two piece shaft? Did you have interference with the pan?

From the picture angle, it looks like you creat more angle on the forward section of the two piece.

And it looks like your pinion angle is pretty good.

One issue is I am running an Atlas up front. I had to shorten my shaft a couple inches due to the shorter case.

I am debating on moving my axle forward another inch and installing some 8* shims.

Before I broke the CV, it was about 28* at the case...

 

[Chaddy]

The picture is quite decieving and doesnt show how dramatic the angle really is. I tried everything to avoid the 2 piece shaft except a high pinion center section which I have ordered from my buddy at teraflex. I also had to limit strap the front end to avoid killing my driveline.

 

[muddybuddy]

man, and you only run 4" lift? i dont see how a single shaft wouldnt be good enough with that little lift??

 

[Chaddy]

The 241 has mad angle issues when you clock them flat with a low pinoin and a suspention lift, then raise the whole piviot on the drivetrain 3 inches to keep it all above the frame rails

in this situation this joint is close to one ton in strength aprox cost 289.00 to swap it- Jess

and they last too. i have been pounding on mine for a year now with out any brakeage

 

[muddybuddy]

i didnt see that you had the 241 clocked....now it makes sense

how much is the hp60 center section? now you are going to have to swap gears and ever as well right? yikes $$$$$

 

[Chaddy]

I have friends down there so I got a good deal...$1000 bucks...I will need get new shafts and I already have longfields and my buddy has a detroit he will swap for my detroit. I will pay around 450 to get it tubed

I have said it before and I will say it again, a 2 piece shaft is not going to fix angle problems, they just make it worse. Only need for them is if you have clearance problems and need to "bend" the shaft around it.

I buddy of mine ran a atlas, clocked flat, and he busted his 1350 HAD CV first trip out. He then went to the 1410 CV and never had a problem since. I think that is your only choice at this point.

I havr ran this shaft out on 5 (hard core) trails and its still alive. And my only choice to fix the angle problem is at teraflex getting built

What transmission was he running? What side drop?

Jesse -

Would you recommend grinding your 1350 CV shaft for extra clearence? I am at a point where it will bind if I flex at all.

I had to clearance my 1350 HAD rear shaft, held up to Montrose a few weeks back but not sure how it will do long term, we will see I guess.

 

[muddybuddy]

hmm now im starting to wonder what i should do for my front shaft...its getting 4" lifted 52's up front. the plan is to go 241sye and then eventually do a doubler later down the road. you think a 1350cv would work for the angle and abuse, or is one of those 1410 42* front cv's going to be necessary to utilize the flex w/o destruction?

I ran my HAD 1350 for more than 3 years with no problems. I ran it with the BDS 6" on the Dana 60 and a 241.

I doubt the 1410 CV will work with the 241 due to the CV large size...

Changing to the ATLAS created two new issues not seen with the 241. The Atlas was clocked up almost flat, and the Atlas is a couple inches shorter, so the front shaft was shorter. Both of these caused the extreme angle that exploded the CV...

 

[Chaddy]

It sounds like its time for a high pinion center section. You already have the bling of an Atlas.........you have jealous parts hehe

 

[muddybuddy]

so what caused the 1350 cv to go? was it the fact that you swapped in the atlas and had to shorten it and increase the angle? it was after you put the atlas in right?

 

[85mudblazin]

What transmission was he running? What side drop?

He was running a Th400 with the shortest adapter AA makes.

Are you using a stock 208/241 adapter with you Atlas or did you go with the short shaft and adapter from AA??

Another thing is I dont think you will be able to clean the tranny pan with the 1410, With his atlas clocked just about flat (the atlas cant be clocked perfectly flat) the cv was rubbing his tranny pan gasket but it did clear

So to fix it he put in 12* shims and went with the 1410 CV.

Another thing is do you really need a flat belly?? it might help to just clock it down 2" or so. Also you would be better off cloking it down some then pushing the whole case up a few inches to get it flat. That will angle the output of the case down a little more.

Yep you got it, the Atlas ia a very short case and when you clock it up it just kills your DL angles.

I havr ran this shaft out on 5 (hard core) trails and its still alive. And my only choice to fix the angle problem is at teraflex getting built

But you dont have alot of flex so that little shaft is never going to see the angle like a rig with alot of flex would.
