I have had to replace all 3 u joints in the front driveshaft along with the ball kit in the H-Yoke. About a month later the horrible noise came back... a loud roaring noise underneath me... took the driveshaft back out and the whole cv in the double cardan this time.... something happened to cause the driveshaft to eat the cv yoke... I replaced it... and it sounds like the roaring is coming back... can someone help me and tell me what keeps eating my cv in the driveshaft?

 

Do you have a lift kit?

It is always my first thought for drivetrain issues.. It messes up the geometry of the drive-train. I had a vibration on my xj as well after 3.5" lift. Transfer case dropped via skyjacker kit (sold in some auto stores locally). Fixed the issue.. smooth and quiet again. However, I would not have described my noise as a roar..

 

Taken pics of your front driveshaft on flat ground tomorrow. Lets see its angle. Also did you put longer lCA on her.

 

Its has the BDS 3.5" lift.... don't think the tcase was dropped though.

 

Did you install new LCAs

 

Don't know.... not the owner who had lift installed... it doesn't say it in the receipts.... if there is any type of spacer between the cross member and frame then it was dropped, correct?

 

That would be correct

 

The reason I ask is sinply because I want to see the angles. See if its bad, how bad ad let you know how well fix it. Also wat kind of u joints did you install?

 

Pics will tell all

 

The angle isn't that bad.. the tcase was dropped. And I put precision and moog in for ujoints

 

X2. Want to see it lol.

 

What is the front pinon angle?

 

Pics..... front dshaft angle isn't much... tcase was dropped....

 

No answers??

 

Take a pic so we can see what angle the yoke of the front diff is at in relation to the shaft, would be helpful.
