| I have a mitsubishi mini truck that I have built using a jeep dana 44 solid axle.Ended up with about 10 in. of lift.I've had a custom driveshaft built for it by modifing the mit. slip yoke to a toyota flange using a toyota u joint 2 1/2 in. pipe for the shaft and ending up with a jeep 1310 series yoke at the pinion end . The decision to use toyota at the trans case was made because it offers the most angle . problem is I need more. Does anyone have a cure for this. Do they make a cv assembly for toyota ? Would it offer more angle ? |

High Angle Driveline. http://highangledriveline.com/ Its not going to be cheap though.
You might want to consider cutting and turning the knuckles on the D44 for a better pinion angle. |

| Actually just got done rolling the pinion up another 5 deg.Doesn't bind at ride height anymore but still gonna be afew deg shy at full droop. Would anyone recommend grinding the toyota components to achieve this ? |

Okay here is the deal. A Toyota CV from a solid axled truck (85 and earlier) is good to 35 degrees max of droop. However, the non-CV standard u-joint shafts are good to 41 degrees.
The 1310 doesn't have anywhere close to that amount of angle. However, Tom Woods makes an offset joint that will give you more angle before it binds. http://www.4xshaft.com/Super-Flex.html
I do think that if you have a short front shaft, then you won't be able to run a CV at all at the Tcase side. You'll need the standard shaft. |

| My problem isn,t at the pinion where the 1310 joint is , its at the t case where the toy joint is. Ive rolled the pinion up to 30 deg. , making the 1310 joint straight with the shaft. Do they make an off set toyota joint ? |

No. They don't.
If its binding at the Tcase then you need to eliminate the CV all together. The shaft is too short, so unless you want to spend $750 on a High Angle CV shaft, then just eliminate the CV. |

| Scotty , I don t have a cv in the shaft.I thought adding one would help increase the angle. Just a single toyota joint at the t case. Even though it offers 40 degress I need a little more at full droop. Is it fessable to do a little grinding on the flange to acheive this? Maybe 3 - 5 deg. The shaft is only being used when on the trail and removed during road use. |

Ahh, okay I get it now. I guess you could grind a little bit, but I still don't see it helping much. Seems to me a limit strap would be better served as you'll be hosing u-joints quite often at those angles anyway.
How long is the front driveshaft BTW? |

| If I remember right , the shaft is 22 5/8 at operating height and 24 1/8 at full droop. It only has about 7 deg. between each. T case points up 4 deg. pinion points up roughly 32 deg. making oper. angle 36 deg. and full droop 43 deg. Engine swap is in the future , but for now just wanna get all 4 spinning and do some wheeling. |

You are likely going to burn up the upper pinion bearing with the pinion that high. I take it its not a HP housing? |

| No it isn,t hopefully parking it on a steep hill and over filling the crap out of it will work. |
