Hello! I am in need of some help. My truck stays parked most of the summer months and I've had a rodent of some kind get into this year and chew things up. I've patched up the wiring, but I have an issue with a vacuum line going to the front driver side 4WD hub. It is chewed off right above where it attaches to the ABS module and for the life of me, I cannot find the other end where it was chewed off at.

I've traced the hosing coming out of the vacuum cylinder, around the back of the upper side of the engine, to the IWE module, from there it splits out into a line that runs to the passenger side wheel, and the other line runs under the engine over to the driver's side (found two more chew points down there, one completely thru the line). It comes up on the drivers side, merges with the hose in the picture, then runs down to the driver side hub.

So I was wondering if anyone has a photo or component diagram of a '08 v8 engine compartment I can look at to try and track down where this hose went or know of where this line attaches into?

Any help would be excellent! We are looking at 3 to 5 inches of snow this weekend.

 

ok, I think I have solved my problem. I found the posting about IWE system from xjcamaro89. In it he has a simple diagram of the system and this shows two blue lines coming up from the hubs as vent lines. Since I can't find where these would connect back into the system, I am going to say that the line that is chewed up in the picture is the vent line and whatever rodent got into my engine bay, chewed on the end, making me think a line was chewed off.

Well, at least I found the other two chew points in the inspection of the lines.

Also, big shoutout to xjcamaro89 for making that posting about the IWE system!

 

Just make sure that the line isn't clogged and it should be facing backward. I can take a pic of my '07 if you need to see where and how it originally terminated...

 

EBC-150, if it isn't much of a hassle, that would be great! Having a visual reference would help out alot.

I'll be checking over the line to see if no debris got into the line from the rodent chewing on it. The Truck has only been driven in from my driveway and into the garage, so there shouldn't be any road dirt in there.

 

As you can see, it just makes a slight bend, facing toward the rear.
