Can you identify this leaking component please?

This part started leaking last night. Noticed a puddle when the truck was sitting.
It looks like some type of line with a rubber boot on each side.
Clearly accessible from underneath.
In the pic, you can see some moisture where the metal line meet the rubber.
In this pic, the leaker is the 2nd line from the left. It has the same hose and fitting on both sides.
You can see a drip hanging at the bottom of the line.
Is this line easy to replace?
Thanks for your help guys!
Here is the pic:

 

Welcome. That boot on the left covers your inner tie rod and appears to have seen better days. The drop of fluid from your lines is likely power steering fluid. That's all part of your steering rack. It should be red/pink because Toyota requires we actually use automatic trans fluid but it looks like you have actual power steering fluid in there. Hard to say where exactly it's leaking from based on this one picture. Are you positive it's leaking from one of those hard lines? You could try snugging it up but you may have to replace it. What's the overall condition of the truck and frame? It looks to have a fair amount of rust.

 

Hopefully it’s power steering fluid...because that’s where mine leaks and my rear main seal needs to be replaced.

 

Thanks for your help guys.
Well, my power steering reservoir appears emply, so thats probably it.
Hard job to repair that line?

 

If that is just a rubber hose over a metal line you might just be able to push the hose back over the line and add a hose clamp and you'll be alright.
Looks like the hose may be backing off or maybe the hose clamp is gone.

 

Yeah, it spent the first 5 years of it's life in New England. The dealer inspected it a few years ago to see if Toyota would remedy it as part of the rust recall. They said it wasn't bad enough. Not a safety issue.
Funny thing is, I asked the dealer to replace my emergency brake cable because it was sticking. He said he was afraid to do that because it was too rusty. WTF!!!!
Anyway, I put a small hose clamp on it and and put in some power steering fluid/leak sealer and it seems to b ok. No leaks at all right now.
Thanks for your help!
