So a little background bought a 2012 DCSB right off the lot I had the 20mph vibe drove it a couple hundred miles to see if it got worse or better no change after 500 miles so I took it in to have them look at it. Wouldn't you know it they said it was normal, whatever, I figured it would probably get worse once I put the lift on which it did.(2.5" in the front with an aal in the rear) not only was it worse it now had the damn take off vibe. So jump on TW and start doing research find out Tom Woods makes a one piece that seems to work well so before I sink $500 into a new driveline I wanted to make sure it was the rear driveline. Oh I took a weekend and screwed around with shimming the axle and the CB which helped but did not eliminate the vibes. So back to my story, I took out the rear driveline put it in 4HI and took it for a drive well well no vibes so I am just about ready to pull the trigger on a new Tom Woods driveline when I notice the spare drivline I have for my 99 4Runner, it has the CV style u-joint at the transfer case side and the slip joint on the rear diff side so I take it and hold it up to the transfer case and lo and behold it fits on perfect take it back to the rear and the bolt pattern is smaller but with the flange the way it is I figure it wouldn't take nothing at all to drill it to fit it just needs to be lengthed. So I call the local driveline shop and they quote me $160 to lengthen the driveline sounds reasonable so I take it down and a few days later they call me and say its ready. Sweet so I motor on down and pick it up take the old one out and bolt on the transfer case side and hold it up to the rear diff and mark the holes, takes about 20 min to drill new ones and then bolt the rear on with some new fine thread grade 8 bolts and take it for a test drive. Guess what NO MORE DAMN VIBES!!!!!!!!! I am freakin ecstatic this was my only bitch on the whole truck besides that it has been great. I have had it in for about 2wks and it is still vibe free.
So anybody who wants to do it the cheaper way this is what you need. The rear driveline is out of a 99 4Runner but I think that gen is from 1997-2002 don't quote me on that though, I did a little research and found the drivelines at some junkyards from $40-150 I remember paying $40 for this one from a pick-a-part so basically for $200 I fixed my vibes. Don't know if it will work for everybody but it worked for me I had that same driveline shop quote me a new one custom built and it was about $550 so this way you already have the CV u-joint and the slip joint they just have to lengthen it. If anybody else does this let us know how it turns out. Oh and for those who think I didn't try hard enough with the shims and CB maybe I didn't but I thought it was a pretty weak design from toyota to begin with but to each his own I guess.
