I notice some lines rip and tore around the drive end rear axle. I need to make sure what’s going on.

Hi,

The first video appears to be a breather from the rear axle. Am I correct is saying the one end is attached to the axle housing? If you follow it to the end, is there a one way vent on it?

As far as the second one, it's hard to tell where it is going. It looks like a hose to the evap canister. Is the check engine light on? If it is, have you checked for diagnostic trouble codes?

I attached a pic below. At the bottom, I highlighted where I believe the hose in your second video is going. At the top, I highlighted the vent which I believe is the first video you sent.

If possible, let me know where at least one end of the hose in the second video attaches to. I will watch for your reply.
