Well, I did something dumb and reverted from my RCV eliminators back to stock. Here's my dilemma. Yesterday, I did the driver side, and the IWE held vacuum. Today, I did the passenger side and it's losing vacuum slowly. When the vacuum gets down to 0, the axle shaft does not re-engage to the hub when you spin the wheel. It will still spin like it has pressure built up which I assume it does, but the pump shows 0. When I disconnect the vacuum pump the axle re-engages to the hub.

2nd issue, to make matters worse, I broke off the bolt in one of the bottom IWE holes. It hasn't been a fun day. Any thoughts on the above? These are brand new IWEs and a brand new vacuum pump.

Appreciate it

 

These two statements seem contradictory unless the gauge on the vacuum gun is what's broken. Did you check your depth on the CV threads prior to torqueing the CV nut to spec?

 

Thanks for the reply. That may be the issue. I did not measure it, I rotated the hub until the axle was engaged and kept rotating and pushing as far back as I could. With that same method, the driver side was easy and holds vacuum.

After awhile, when the vacuum went down to zero it did disengage and I could hear the grinding when I turned the hub. So I tested my lines after installation of the new solenoid and both sides were getting 17-20 steady without any loss in vacuum. With that said, if I had a slow vacuum leak on the problem side (passenger), would you still advise that I drive it? Really hate to tear it down again. Not to mention I’ve got a broken bolt in the damn IWE (2/3 are good; I put locktite on those two).

 

I took off the wheel and made sure it was seated properly and it is. The IWE still loses vacuum at about an inch every 2 seconds or so. Could it be a faulty IWE/Hub? Wondering what I need to do.

 

If the IWE doesn't hold vacuum it may have been damaged.

 

Agree, that is if the vac pump was connected directly to the IWE. The hub doesn't care about vacuum, so if hooked up like I said, I'll betcha the IWE seal is bad.

 

You were correct sir! It was a bad IWE. I ordered it from RockAuto as a 2 pack. The other was fine. Glad O’Reilly was open. It’s installed and holding vacuum. My brother in law was here today to help me get the bolt out too. I’ll put the RCV eliminators on the shelf hopefully for the duration of the truck’s life. Thanks for the replies. It’s hard for me to believe these brand new parts come in defective, but I guess it happens more often than I think.

 

Great, you're all set to go, good deal.
