Since I decided to get rid of the doubler I had to make two new driveshafts and re-route the exhaust. Rear shaft was no problems however I ran into some issues with the front.  Uploaded with ImageShack.us Uploaded with ImageShack.us Uploaded with ImageShack.usThe u-joint at the t-case sides is sooo close that if the suspension cycles it would bind the joint. As you can tell from the last picture the type of yoke I'm using (similar to the one on the right) is too shallow so there is no room for the joint to move and not enough material to grind off. So I need a deeper yoke like the others. Anyone have one they want to part with? To fit a 2" tube. |

yokes are normally really cheap at parts for trucks or drive products. mine were only 18$ each.

Looks like the bolts for the strap would hit first. Perhaps a U-bolt style yoke would help. You might be able to convert that to a U-bolt style by drilling it out, IF there is a large enough flat area on the back side for a nut to fit.

Couple of my buddies did their rear d-shafts with ford u-bolt straps from a front d-shaft that i gave them , worked well but yours might still be too tight .

I'll try to remember to look through my driveshaft parts, I probably have a deeper yoke. I should have u-bolt yoke for a 300 too.

Yokes off of a dana 44 will fit the 300. As for the drive shaft yoke,I modified a slip yoke to fit in the tube instead of a weld yoke.

I was just in the shop looking at the slip yoke and was wondering if I turned it to fit the 2" .25 wall DOM I have would it work...  Didn't think about the 44 yoke. I may even have one around here somewhere but will try the slip first. Thanks to Steve (beaver on the board) for the driveshaft. |

i got a question about drive shafts, i got into this sort of problem with my back shaft, can you put a double cardon joint on the back shaft?

for most TJ's or YJ's with more than a couple inches of lift, it is recommended to have a rear driceshaft with a double cardan joint on the t-case end.

As was mentioned typically on a short wheel base like a YJ it is a good idea to run a double cardan shaft as the driveline angles are too great for the normal driveshaft. A double cardan shaft is basically 3 u-joints instead of 2. Where the upper two joints act to reduce the operating angle of the joints by half for each joint involved. Then you shim or somehow rotate the pinion up to more or less point at the trans output thereby reducing its operating angle as well. That was a pretty quick explanation and there is a lot more detail than that involved but just get the double cardan shaft and be happy!  See pics attached.
