Did this permanently fix the issue? I currently have the same noise and I am wondering if greasing the U-joints was the fix. Thank youSo I greased the crap out of the U-JOINTs, they were bone dry and most of the noise is gone. I driven it a few days and can still hear it once in awhile but it is really faint and not long periods like before, no other work done- weather did get a ton colder tho. I hope that helps in any way.
Hope that helps.
