Hey everyone, I have a 1987 Ford Ranger with the 2.9 six. It is four wheel drive (although the front diff is toast). I bought the truck off of someone who has no respect for vacuum hose. There are vacuum hoses missing, and poorly replaced with hose that is ill fitting and kinked. I work at an auto parts store, so getting the right hose and fittings is not a problem, but I am having a heck of a time finding a vacuum diagram for this truck. I checked Mitchel's on demand and Chilton and Haynes books, and the only vacuum diagrams I could find have nothing to do with my actual truck. I ahve a few specific questions if anyone can help. There is a vacuum switch at the very front of the air intake duct that is disconected, and also some on the throttle body that I suspect to be incorrectly routed. If anyone can help me out by pointing me to a good diagram, or with these questions in particular, that would be a huge help.

Also, I am looking to replace the front differential and get the four wheel working again. I want to use the stock rear, but I wanted to know if there are any options for the front axle shafts. Are there any axles that don't use the intermediate shaft on the passenger side that would work? I want to get rid of the twin beam suspension in the front and go with a solid front so the jack shaft is not really necessary. By the way...do solid fronts exist for this size truck?

Thanks for the help,
Alex, the Annoying Ranger Guy

 

Welcome to FTE!

This thread involves an '89 2.9L, I think it should be similar:

You might also try the Autozone website, they have repair manuals online and you just might get lucky.

 

Look under your hood, a vacuum diagram is on a sticker in front of the radiator.
