SYE installed at 3"lift, now 4" lift= vibes??

To make a long story short, I had an SYE kit installed when I had a 3" lift installed, now that I have moved to a 4" lift kit, I'm feeling drivline vibrations. Is there an adjustment that needs to be made or something? I appreciate any help you all could give me. Thanks.

did you re-adjust the angle of the rear axle to point toward the TC?

Take a look at the rear yoke, it should be pointed at the yoke on the TC

If you are going from truly 3" to truly 4", the driveshaft you bought when you did the 3" lift should still work, so you should be able to correct by adjusting the upper control arms. Just out of curiosity, did you drive without the SYE when you did the 3" lift, or did you do at the same time?

You need upper rear adjustable control arms to make the adjustment.

Just crawled under the Jeep and saw what your talking about. It doesn't look to hard to install. Will it be easy to make the adjustements, and do you have any suggestions on making them?? Thanks for your help.

Like otis said you'll need adjustable control arms first. If you have them already (in most cases) you just have to unbolt 1 end and give it a few spins to lengthen the arm. Pay attention to how many turns you do and do the same amount to the other side. Once everything is lined up better tighten the jam nut again and give it a shot.

Yea you can put a jack under the front of the diff than remove one end of the upper control arms. Jack the front of the pinion up until it's lined up then adjust your control arms and put them back on.
