I had to bring my 2013 Ford F150 XLT, with only 41,000 miles, for a grinding noise on the right front tire. Come to find out it's the bearing. It was repaired under warranty. The repair service rep said it's a one piece bearing. Never heard of that. I remember the old days when you could take it all apart and repair it yourself.

 

Ford has had a lot of modular parts on their cars and trucks for years. Back in the early 80's I bought the wife a new Cougar. To my surprise the rear axle bearings started making noise so I thought no big deal, just have new bearings put in. Nope. The ENTIRE rear axle assembly had to be replaced. No serviceable parts in the rear axle. I couldn't believe anybody would be so stupid but.....the cost of the axle assembly really wasn't bad at just over $200. 1980's money. So today we have even more non-serviceable parts on our vehicles. Wait until you try to replace U Joints, LOL! Or maybe valve seals in 2.7 or cam bearings ....or. No, it doesn't get any better. Everything today is either not serviceable or it's considered disposable. The true reality though is there are no mechanics anymore, just new parts fitters. If they can't read the code, they don't have a clue how to fix it. You might find one or two guys that will attempt a diagnosis and then tell another guy what to fix. That's how most dealerships work these days.

 

On Ford's 2wd F150 trucks, it has been integrated into the rotor with a single use nut that needs to be torqued down to exactly 295 ft/lbs.
