Are those of you running centered rear diffs, just running the stock tcase with a double CV shaft? Buddy has swapped in a D44 and had a shaft made, but no CV, I am thinking it will vibrate like all hell...anyone got experience?

It just depends on how much of an angle it is. I know people run yota axles with their regular suzuki shafts not even CV and they say it ain't to bad.

I run a centered rear diff with a stock t-case, however I have a Toy CV. Works well for me...:)

same here ...I have yota axles,had the stock sami shaft and it would vibrate the whole t-case bad in first and second.I put the larger out put flange on the t-case ,redrilled it for to and put a 1979 front cv d/s from a toy p/u.No more vibes and way beefier.

it's all about the toy cases :D
