[QUOTE="Bee, post: 1873916, member: 31937"] I got a mityvac and checked vacuum. The system held at 20 mm Hg forever. But, it has been abnormally warm in the Northeast. The noise was bothering me enough that I decided to take advantage of the warm spell last week and change out the IWE myself. $160 for the IWE, nuts (upper control arm, tie rod, and half shaft), and dust cap. It was honestly easy; I'm embarrassed I took it to the dealer for this. Followed all torque specs and used the mityvac to retract the IWE. I did not have to remove the brakes (Roush Alcon kit). A second pair of hands definitely helps to control the spindle, especially with the added weight of the kit. I wanted to share how surprised I was at how easily the vacuum hose pulled off the fitting at the IWE. It came off so easily hell I was shocked it was still even attached. Like I said, I changed out the solenoid and checked vacuum, and you have put effort into pulling the vacuum hose off the solenoid fitting. The IWE fitting is smooth, with no barbs. Add to that, the base of mine was corroded, and actually lifted the hose a bit (see pics). Just a theory, but I could easily see how the system could hold vacuum in your driveway, but get rattled enough by suspension movement to intermittently loose vacuum. By the time I discovered this I was more than halfway home so i just changed out the IWE anyway. But, I put some grease at the base of fitting (careful not to get it in hose or hole) to prevent corrosion. My passenger side hose pulled just as easily, a I put grease at the base of that fitting to help achieve a better seal. I may try small zip ties next. Its just been a couple of days so the jury is still out. [/QUOTE]
