lift kit

i have a 2001 xj with a D35 rear, and im planning to put a 3 inch RE lift on it. i was wondering if any of you guys had drive line vibrations, and what you guys did to solve it. i need to know what my chances are to escape buying the SYE kit, and put some shims, and maybe that will take care of it. thanks.

Mine has a Chrysler 8.25 rear axle, but with just factory Up Country sprins (about a 1" lift) I have serious vibrations.

Anyone lifting a '96 or newer XJ with the "improved" transfer case output shaft should plan on doing an SYE. Period.
