Go to autozone.com, they have vacuum diagrams. Register your vehicle, it's free. Click on "vehicle repair guides". Click the emissions link, I believe, then in the left column click vacuum diagrams.

I don't mind posting a diagram but mine usually get deleted. I think the site is worried about copy wright issues?

If the brakes work but you have to push very hard, try checking the vacuum supply to the brake booster with the engine running.

Have a compression test done ,and look for a vacuum leak near the cylinder,like a vacuum hose or intake gasket.If the compression test shows a fluctuation between the 3 and 4 cylinder,then the head gasket would need to be replaced.

chilton has a great book sold at chapters and indago usualy 30 bucks or so

but if you are real desperate goto the dealer they will show you

the 4x4 don't use vacuum. the front is auto lock when the transfer is engauged with the button. if the light don't which when pressed into 4hi or 4low. the motor on the transfer case maybe hung up. they have to be used at least 4 times a year not to go bad. the motor is on the back side of the transfer case. best of luck.
