Angles deff to high .

 

Ds not hitting at other end theres two different kinds that bolt to case ? Are the three shafts you tried all same kind ?

 

No, two of them are front xj shafts and the one that's on it now is a zj shaft

 

Can ya post a pic of other end.

 

My whole thing is...if the angle is too high with the tcase drop in... then with the tcase drop out it would make the angle better....but even with a better angle I get more vibes with the tcase drop out. This is why I'm puzzled

 

Theres two different style on the other end one will bind if angles to great .

 

Less angle at rear might be causing worse angle at tc case end ...ya gotta eliminate what its not.

 

Xj shaft on top zj on the bottom. They are identical double cardan joints

 

I guess vibes were present b4 sye

 

vibes were slightly present before the sye, but I was only at 3.5"s then with the 1" tcase drop. When I installed the SYE I also installed a 2" extended shackle in the rear.

The vibes now are worse now at 5-5.5" of lift with the SYE and tcase drop, then they were without the SYE at 3.5"s

When I first installed the SYE I did drive it at 3.5"s for a day, there were no vibes then, but the jeep looked goofy with the front sitting a 5"s and the back at 3.5"s which is why I installed the 2" shackle.


is the D35 a much lower pinion then a C8.25? because I plan on doing that swap in the near future since I want to run 33's or 35's my thinking is I can justify the 8.25 a lot sooner if the pinion is higher and it will be easier to get rid of vibes

 

might need 2degree shims drop shackles also pitch yoke up.

 

Im having a similar issue. Part of the problem was my front shaft. When I went to 4.5" the front pinion angle was WAY off. I added some LCA drop brackets and adjustable LCA to fix it. I still need to find a new shaft so the old one is out. However I still have vibes as 60+ mph. Had and alignment down and the tires balanced and nothing changed. I have 4 degree shims with extended shackles. I measure the angles and they about 1 degree out so I should be fine at 60 mph. Im trying to find another ZJ shaft and see if that changes anything.

Blue, I was thinking we should swap shafts, no homo and see if the vibes swap with them. Then we would know the source of the problem I would think.

 

I've tried all three of my shafts in the rear of the jeep with no front shaft in. Still get slight vibes in don't think the shafts are the problem. Idk anymore lol

 

us LI guys have no luck lol.... im vibe free but havent done my slip yoke yet plan on doing it good luck guys. and blue i never see you at your own meets guess im showing up to late in the mustang. Blue Fox Gt on slicks and welds..
