installed my new MM manual hubs - do i need to block the ESOF lines?

[blue89turbo]

Hey guys,

Like the title says I installed my new mile marker hubs and everything seems good in 2wd, 4x4 and 4x4 low. I haven't plugged the vacuum lines yet and am wondering if I even need too? what is the reason for doing that again?

Thanks for the help

You should block them so stuff doesn't get sucked up into your lines, but I've run without them being blocked before and I didn't have a problem with a vacuum leak preventing anything else from functioning.

Yes, you need to block them...It will make the Vac pump run 100% of the time. and at 135.00 a pop theyre not cheap. One day you go to use your Vents...you will only get defrost.

Cap the Line up at the bracket. Also plug the hole in the hub. lockouts are so much better =)
