Front diff bushing?

I was changing the oil for the first time on my 2014 Tundra. Noticed that the bushing pictured on the passenger side was loose and hanging a half inch low. The driver side was tight.
Is this a front dif bushing? If not what is it and how do I fix it?

 

Yes, it is a mount for your front diff. Have you tried tightening it? I’d probably take it out and put some red loctite on it first.

 

What @Cruzer said, there's a nut on the top side that just needs to be tightened. There's not a whole lot of space up there, box wench is your best bet.

 

I did try to tighten it. It didn't seem to be catching on anything and just spun...
I will try to feel around up there and see if the nut is sitting up there..
