HI, I'm new to this forum

I drive 2010 Ford f150 4x4 5.4L

I have put in Rancho leveling struts and shocks and after doing that I noticed ratcheting sound in front wheels . Trying to do my own work on my Ford f150. I did some research found out that it may be IWE problems. When putting in struts I didn't do anything with CV joints meaning unbolting center bolt on wheel hub. I only unbolted the upper ball joint and the sway bar linkage to lower to get struts and shocks in and out. I've done vacuum test on all points of system and encluding at the wheel hub actuator , and found to hold vacuum. I also checked the solenoid switch and vacuum on 2wd and no vacuum on 4wd. I'm stumped can anyone help me?

IF I have to do a wheel hub actuator replacement I need help with the CV joints. The CV joints on a 2010 f150 is not a bolt in kind, it's like a driveline yolk. I did some research and found nothing. Please help.

Oh, one more thing does anyone know what is the vacuum lbs. that the IWE system should have?

Hi Mainah22
I have the same year truck and check valve. I'm curious how you checked it, bc I was able to blow throught both ends til I tried to cover the side opening that go's to the back up tank?

I've had the same problem my 2013 for a quite some time now. Started shortly after I had my lift kit put in. Just ordered check valve yesterday and will put in on friday!

Replaced the check valve, solenoid. Doing hoses this weekend. Ford could not duplicate the problem, so I have to fix it.

If you damaged your IWE's there's still a good chance that they'll hold vacuum. You don't damage the bladder when you do this, you damage the plastic parts that hold the ring that slides over the axle end and the wheel hub. If the system works correctly, it shouldn't take much for the axle to engage the hub once vacuum is removed, it should happen pretty much right away. The best tool for testing all this is a hand held vacuum pump that has a gauge. These usually are reversible so they can pump pressure too.

Having similar problem with my 09 5.4l but when I look at the booster behind the brake fluid reservoir I don't see anything like this? is it different on the 09's from the 2010's?

If your looking for the IWE control valve on an 09 its attached to the fan shroud.. When my iwe were grinding I replaced the control valve and check valve and the problem was fixed.

Budman1962 could you share a pic of where it is on the fan shroud?

Right in front of the passenger side valve cover.

Interesting.... my 06 had it on the firewall, as did my 11 and my 16.

I wonder if they played around with different locations over the years trying to find the best spot where it would stay dry?
