vibrations

I just went from a Rusty's 4.5" lift and added 3/4" coil spacers and 1.5" shackles. I also rebuilt my t-case and got a SYE (Advance Adaptors hd kit from Tom Woods). I installed everything, and after I finally got it all working, I have horrible driveline vibes. Almost like having too much lift and no SYE. Does anyone have any suggestions? I took off my rear swaybar but I don't think that has much to do with it.

Thanks in advance,
Andrew

You need to check all the angles and shim accordingly!

Front angles, rear angles, both? Do you know about what they should be?

thanks.

Your pinion should be the same as the driveshaft less a degree or two for axle wrap.
