front end humming

[Renklaf]

I'm new to this forum. I did a BB to my 00' XJ. After all was said and done I have this humming sound coming from my front end when in 4x4(during acceleration). Does anybody have any idea.

Driveline angles maybe?? Are you getting any vibes? Did you check your caster and driveline angles after the lift?

i dont feel any vibes and the angles look good.
