Drive shaft squeaks

so as I'm either going slowly up a hill or start to accelerate at low speeds my driveshaft squeaks, and as everyone here can relate we all love our tacomas so hearing an abnormal noise really pisses me off and annoys me. I found that it's coming from the rear yoke if I'm using vocab right, but it's coming from the yoke that attaches to the diff. Do I need to replace the whole thing or shoul I get a new bearing kit. The zyrk is broken and if you look up into the hole there is some metal that shifted over the hole a little bit

 

The yoke or the last U joint? The U joint is where the grease zerk is. Sounds like a bad U joint. Have all 3 replaced if you're doing one.

 

Yes. Universal Joints, if you do one do all three. If it is squeaking it is dry and could come apart which you don't want to do at highway speed.
