Default Clicking/Grinding Noise after install

I searched the forum and I could not find a solid answer on this.

I just installed a 3" Teraflex lift with front lower and rear upper control arms. I kept the front drive shaft in hoping I could get some use out of it. When I went on my test drive right after the lift was installed all I could hear was the clicking/grinding noise. So I changed the front drive shaft with hopes the noise would go away, no luck. I believe the noise is coming from the front drive shaft where it connects to the front axle.

I rechecked all the nuts all around the jeep and everything looks good.

Any thoughts or suggestions?

Thanks for the help. I can post a picture of my pinion angle if needed. If it is my pinion angle how is this corrected.

Look at the front drive shaft where it comes close to the engine oil pan and trans skid plate.

Did you try driving it without the front drive shaft installed at all?

If it is my pinion angle how is this corrected.
What is your caster now? Toss an angle finder under the C's and let us know the number. Check the 'Setting your Caster' section here:

And is the front axle re-centered, or still off to one side? (which could bring the driveshaft over far enough for contact like Robar is thinking...)

I have plenty of clearance between the front drive shaft and the trans skid plate.

OK, I read the write up. It talks about adjusting the front upper control arms. I do not have uppers. I have lower front control arms. Can I do the same with the lower control arms and make the right adjustments. Thanks

Upper or lower, or both sets. Doesn't matter.

Uppers only, you adjust them 'shorter' than stock to raise your caster.
Lowers only, you adjust them 'longer' than stock to raise your caster.
Both sets, same as above, you just have more flexibility and are able to move the axle forward/backward in the wheel well.

Other than the noise, you didn't mention how it drives? If the handling is ok, you might pull the driveshaft back off and see if the noise is still there before messing with the caster. If the handling is poor, though, too little/much caster may be causing the driveshaft to bind?

Anyway, let us know what you find.

Everything is all taken care of. My caster was at 11.5. It is now at 6.0. My lower control arms had to be shortened. Thanks for the help.
