Pretty simple to replace. Some don't have to-but I did-remove the O2 sensor attached to the catalyst converter. Just remove the (4) 15mm bolts from the diff side of the driveshaft, and then remove the (6) 8mm bolts from the transfer case side. And the pry the CV head of the transfer case flange (it's a minor pain in the rear) with a flathead. May also help my tapping the flat head with a soft headed hammer to get it out. After that just finangle it out and replace the CV head.

I've been looking online for the driveshaft cv rebuild kit and only finding parts for 2007 and below, any one know what I need to use or a suggestion on where to go for it?

Awesome Thank you!

I found after removing the driveshaft the noise was still there, I decided to sit down and list what I've done to it lately, then realized the noise first stated when I replaced front rotors and pads and forgot to lube the caliper slides, pulled the brakes and I found only 1 slide was able to be easily removed, lubed them up and noise gone, so it was more rotational. Thanks again for all the help everyone
