    Vibration after new CSB & subframe bushings

    This weekend I installed revshift subframe bushings and RTABs. I got the subframe riser ones and installed the differential spacers which accompany the kit. I installed a new CSB also while I had them out bc the old one had a crack in it and produced a mild vibration in 1st gear. Giubo is also new (<10k miles).

    Now after getting everything all buttoned up I have a vibration from top of 2nd to bottom 3rd when I give it the beans. At freeway speeds theres no vibration. What could it be? I preloaded the CSB and all the bolts are tight at the tranny and the differential. I maybe, maybe forgot to tighten the collar nut that combines the two driveshaft ends. Would this be it?

    I've also done the driveshaft multiple times before so I know the process and I lubed all the joints w silicon spray.

    Going to go back under today but wanted R3v's input.

    Thanks guys.

    I'm sure it has always been there, just that the new hard bushing makes it more noticable. After I replace my subframe bushings with akg stuff, the differential got louder and some vibration that wasn't there before.
