Tip & How-To about Ford F-150
To change your rear axle bearings on a Ford F-150 the first thing that you need to do is block your front tires and support the rear end on jack stands. You will then need to remove the tires from the back also. You can pretty much start any 1 of 3 places, either tire or the differential(is the round container that both axles run into). I would start at the differential so that all the gear oil can run off before I get back there.
You will need a 10mm socket to loosen the bolts on the cover of the differential. Loosen the top bolts but do not remove yet, then remove all lower bolts so that oil drains into a receptacle. Keep the top bolts in to keep the oil from gushing out every where. when done draining you can take them out and remove cover.
While thats draining move to the rotors(where the wheels bolt on). You need to remove the caliper which is where the brake pads are held to stop truck. To remove calipers,you have to remove two bolts 1 at top of caliper and 1 at bottom. After you remove those bolts you can remove it from the rotor. Next, remove the rotor itself(if rotor sticks apply some rust buster to loosen up parts and maybe a little heat( i stress little because you could damage parts) NO BEATING on rotor, unless you want a bigger problem than you started with. After removing the rotor on both sides of truck return to the differential. Now that oil has all drained remove cover and look inside. You will see 1 big gear wheel that turns a little group of 4 littler gears. You need to take the fat metal pin that is in between those four little gears out. To do that you will need to remove the small bolt that is in the top of the pin. If you can not see the bolt or you do not have access to it, you will need to put truck in N so you can spin the gears around until the bolt is accessible. When you get the pin out, you may have to spin gears again to remove pin completely. Now that the pin is out you will need to push the axles in, they should slide in about a quarter inch or so. Now if you look where you just removed the pin from, you will see your axle end. In order to be able to pull it out you need to remove a C shaped washer from the end of the axle. You can use a pair of needle nose but since its so slick in there from oil I just push it off the back with a screwdriver or something like that. Now you can remove axle. Just pull the end of the axle(where tire attaches) straight out from truck. Finally to the point of this How to. The bearings will be sitting just inside the metal tube you just removed the axle from. First you need to deal with the grease seal that sits right in front of the bearing that needs replacing. Use a slide hammer believe me you dont want to attempt this job without 1. You can usually borrow 1 from your local parts store.Remove old bearing and seal with slide hammer and insert new bearings and seals. Now you are ready to put it back together. Don't worry putting together is just following these steps in reverse. Don't forget to refill gear oil when you are complete, and anti slip.

Well you have to remove the whole assembly
With a 30mm deep socket , remove the axle nut, do this before jacking the car up...
Then jack the car up and remove the wheel.
Then the tie rod end , brake caliper and lower ball joint.
Remove the cross bolt and brake hose bolt on the strut.
pull the assembly off of the strut.
The you need a press to press the old bearing out after you remove the inner snap ring.
press the new bearing in and install a new outer seal and a new snap ring.
reassemble and if you are using a new hub pull it onto the bearings with the axle nut
