Broken D300

[Kodiak Dodge]

He is running a rear 14 bolt with 4.56's.

Umm, let's see, the rear shaft used to be 26". I moved the 14 bolt rearward 2.5", and the new rear shaft is 18.5", so the new configuration consisting of a TBI350/TH350/NP203/D300 is about 10" longer than the factory junk, which consisted of the 258/999/D300. The angle at the t-case output is pretty severe. About 27 degrees at rest. After much discussion with Tom Woods, he recommended going with their new "Super-Flex" u-joint in the forward end of the rear shaft. He said that the super flex joint would offer a much higher angle of operation than a CV, and would hold up alot longer. I must admit that I was a bit skeptical, but trusted his judgement. I'm not dissapointed. He told me that the drawback to the super flex joint is that I may experience vibration due to the characteristics of it's offset design.

Here is a pic of the D300/NP203 combo

Here is a picture of the rear driveshaft sitting on level ground. Very extreme.

I think lengthening the wheelbase a couple inches would be the best way to deal with it.
This is the first issues he has had with it but the Jeep did sit most of the summer. If it was mine I would go give a four link a shot and push the rear back another 4-6 inches
