Vacuum hubs grinding over and over
2017 f150 4x4 with 3.5 ecoboost. Really disappointed in Ford quality. The four wheel drive system relies on dozens of cheap plastic parts. Mine has failed over and over. I have been in a loaner for 24 days so far this year. And only 6,000 miles on the truck. Many other issues as well. I am kicking myself for switching from Toyota to Ford. Never again. I can't see how Ford can hold on to #1 with this kind of poor engineering and quality.

Tundras use vacuum actuators as well...with plastic parts.

It sucks but, all manufacturers have some sort of issues that plague them or they don’t seem to want to fix.
Have they replaced the check valve and/or solenoid yet? If all they are doing is replacing the hubs and it continues, they aren’t addressing the cause. New hubs, unless defective or installed incorrectly, should not have any leaks and cause grinding. Thus, they shouldn’t be the cause anymore.
Also, I have read now that 2 members have had similar grinding that turned out to be the front diff.

It dawned on me earlier about the repeated failures on some guys trucks, and how some after front shocks [lifts] are installed, is when the problem sometimes start.
I don't know the shop manual procedure, TBH. But, I do know there is a right and a wrong way to reinstall the halfshaft back into the hub and IWE. Before reinstalling the nut on the end of the "spindle", the gear teeth need to be lined up, so when tightening the nut, the gears will mesh and not bind, possibly cracking the sliding gear in the IWE. Preferred way, IMO, would to use a vacuum pump and apply vacuum to the IWE, insuring it's not in the engaged position, which it will be with no vacuum. To align the teeth, just rotate the half shaft, and watch the hub that it is engaged.
Another thing my dealer told me, was that some IWEs are coming in with too much grease prelubed, and they've had luck cleaning out excess grease.

Curious to see how the new RAM is holding up. I am getting rid of mine as soon as the legal work is done, and may jump ship. So tired of things breaking or not working properly on this truck and seeing people still having the same issues on 2 year newer trucks leaves me to believe the Ford is really starting to hit rock bottom. So far, all new front except for one axle, and it is back to groaning when I come to a stop, vibrations are still there, steering is back to being wonky, LKA is crashing again, Sirius still cuts out at random and has been "updated" twice, and final straw, the damned passenger seat broke again, clunking when I hit bumps.
I could buy a really nice Luxury car for what these trucks cost, and if I could tow with one, I would!

You're gonna be jumping for joy to be rid of that one.
