Does anyone have good pictures, repair guide/drawings of the vacuum pulse solenoid, and the vacuum lines leading to the hubs?

Trying to do as much research on this, before I go diving in!!

Thanks!!!

I can probably find a picture or diagram of the PVH solenoid if you need one, but there is no diagram of it's internals. It's not considered a repairable part. You just replace it.

I've never been able to find a complete vacuum diagram, but it's pretty simple. A vacuum line coming from the intake manifold goes to a reservoir with a line going to the HVAC and another going to the PVH solenoid. A line comes off of the solenoid and goes down to the axle, where it T's and goes to each hub.

 

I just got done troubleshooting my ESOF. See these two links:

The OP has a gas engine, so he won't have the electric vacuum pump, and his reservoir will be different. But everything else you posted is correct. On a gas engine, vacuum is taken from the intake manifold.

 

Wasn't thinking straight. It should get him going though.

 

Thanks for all the info --- that should get me started in the right direction!!
