What is this line?

[big sig]

I was driving from Hickory, NC to Blacksburg, VA today and when driving on the interstate at about 75 mph I heard a noise that sounds like when I rock sticks in the tire and fly's off. Well I knew that wasn't what happened so I pulled off at the next exit. I looked under the driver side wheel well and where the 2 lines run from the frame to the brakes one was broken. I drove 100 miles after it happened and stopped by the dealer here. They wouldn't even take a look at it until this afternoon and I have an exam at 10:45. So I thought I would ask you guys. And tomorrow I'm driving back home, so is it a major problem or will I be ok to drive the 150 miles? Its the one on the left you can see where it is broken. To give you and idea of where it is the white thing in the left corner is the shock.

Photo's a little blurry, but I think it's your vacuum line. If you don't need auto 4X4 it's fine.

Ok thanks. I can still lock it in with the hubs right?

It is the vacuum line and yes, you can still turn the hubs for 4x4.

was it raining? it looks wet. If it is a vac line, not a big deal, you might burn up a vac pump with it running al the time, but you can make it back. Yes you can just lock the hubs in and 4x4 will work.

Oh, and pull the vack line off the knuckle, that might be the rock sound.....

Yeah it was raining. Is the vac pump running all of the time with the line broken?

I wondered the same thing. I went out to my truck and looked at it and the top one is the vacuum line though.

at least that explains the wet look. If you have a twig, bolt, or something to jam in the broken line, that might seal it up for now. If the pump can not get the disred vacume, it will run until it does. That and your defrost will be your only option until the vac leak is fixed.

could be worse

it is a easy fix, just replace the vac line. You might have to get new hose conectors, but not that bad of job.

I switched to manual hubs, so no ESOF

Ok. Ill find something to put in it to try and stop it. Thanks for the help!
