4x4 vacuum questions
I just bought a 2005 Expedition and am going through the 4x4 vacuum tubing making sure there are no apparent problems. I spotted a dry rotted hose which lead me to these findings:
Two things - in pic #1 there is a loose hard plastic tube. I'm not even sure this is part of the 4x4 vacuum system, but is it supposed to be loose? in pic #2 this hose with check valve goes to the brake booster. I can blow and suck which to me means the check valve does not work. Correct? FYI when I unhooked this hose, it was under vacuum and hissed as it sucked in air for several seconds. https://cimg8.ibsrv.net/gimg/www.f15...122d5874ff.jpg https://cimg7.ibsrv.net/gimg/www.f15...5cebec5198.jpg |
