Super Duty Lockout Hub Upgrade and Vacuum Line Delete 

Appreciate all of your videos. Super detailed and helpful.

Nothing wrong with the stock hubs. I don't get why everybody insist on trading them out when they have a Emmanuel Locke feature

How do i stop my 449ss from clunking when they're in free stub shaft is ok the wheel hubs are ok the u-jonts are ok i am on my second pair

Mile Marker hubs are garbage. Do yourself a favor and go with Warn hubs.

The factory hubs were definitely bad, had to leave them in locked position all the time, left front would not go free!

Like something trying to engage, but also sounds like gears! Drove after changes and right off had the same noise like gears crumbling, then drove again and everything was fine? Had left wheel of and everything seemed fine, no noise whatsoever! Hoping it’s vacuum related?

Just changed over to these, still here a noise in the left front but everything checks out, could the vacuum actuator still be trying to kick in??

Cant you just do all that and leave stock lockers and manualy turn them ?

After 6 years lol how have the mile markers worked for you?

Is mile marker the only brand option to use? Mine is a 2005 Ford F-250 Super Duty Lariat.

Will the 4x4 esof switch still engage 4x4 if hubs are unlocked?
