So I am just about to bleed the brakes then set the truck back down on its tires after a week of work installing the 5.29's. I have searched and I cant find out if it matters where the 2 vacuum lines go on the 4wd unit on the front diff. I should have marked the lines but.... There are 2 of them coming from the engine bay, and two nipples they can go in, one is on a black diaphragm looking thing and and the other is on the 4wd unit thingy-m-bob. Let me know if i need to post pics.

Thanks

 

Never mind I figured it out! ha

 

it doesnt matter, per say. but if you want 4wd, yes it does matter
