with the new tcase i put in and redid the sye. i left the output a little longer this time but now i have vibrations. the longer output makes the drive shaft hard to fit in. at ride height it has no up travel slip. im assuming this is where my vibs are coming from. so would adding shims fix this or do i need to make the rear lift lower or make the tcase out put shorter? i dont want to pull the case agin after all the hassle i had getting it in.
