after lifting my truck (fj-60) 5" (4" springs, 2" shackles) the rear driveshaft vibrates
i've tried 4 deg., 6 deg., 2 deg. shims and it still vibrates
i was putting 'em the thiker side to shackle, correct me if im wrong

could anyone tell me how to mesure the pinion angle in the rear?

i stoped by a driveshaft shop and they told me they have a CV joint with a drive shaft what has to be shortened to fit my truck,
everything $160

what do i do?

I ran into the same problem and a cv shaft was the only thing that fixed it. Contact a guy that goes by onetoncv on this board I hear he make very good shafts. I got mine from Arizona Driveline and am not impressed by the quality, but it's doing its job and has not broke after some serious rock runs. good luck. <IMG SRC="smilies/beer.gif" border="0">

thanks for expensive news
i also forgot to mention another solution that a guy in the shop recomended
he advised to drop the t-case one inch so it will loose some of that angle
whats is i think the easyestand chipest way to go
but i may also run into other probs like t-case shifter and tranny shifter...
and the main thing is:it's actually DROPING the t case.

What you need is the back of the t-case and the rear third member flange at the same angle so they are parallel, but how you achieve this doen't matter. I think dropping your t-case to match the flange will work, but as you said there are issues there also. I assumed you had done everything to get the two parallel already and had no luck. Some trucks just seam to want a cv shaft <IMG SRC="smilies/biggrin.gif" border="0"> . It's just me but after all the time I put in trying to shim things that didn't work and now having to drop my t-case and tranny to repair the seals that the vibration toasted and anything else the vibration smoked I would say fix it fast our your going to spend more then the 160 in the long run. By the way since mine was for an fj 40 It cost me 350 including shipping to get shafted so if they quoted you 160 to convert yours jump quick. enjoy your search <IMG SRC="smilies/biggrin.gif" border="0">
