Re: remove front axle from differential on 2003 dodge ram
That works fine on a relatively new vehicle but one that has run in salt etc you'll save a lot of time if you remove the steering knuckle completey by separating lower ball joint and outer tie rod end ball joint and bring the whole steering knuckle to a bench to separate the hub/bearing. Soak everything with penetrant, loosen the bolts a few turns and try hitting right on the bolt heads. I also made a very sharp wedge from a chisel and rammed it hard on the other side to seoarate the hub. It will finally come apart then you'll see all the **** that was binding it due to an alumininum knuckle re-acting with a steel hub. Clean the hole and grease everything and fit new bearings

Lift and support front end on suitable jack stands preferably on frame. Remove right front cv axle, stub shaft, and seal. You will need to pull the right front brake caliper assembly loose and place to the side. Then remove bolts from shock and upper control arm and hub nut to do this. Next, remove axle lock actuator on passenger side of front axle. Place a drain pan underneath front diff cover and remove cover and drain axle. In the center of differential there will be an 8 mm head bolt holding spider gear cross-shaft. Remove bolt and cross-shaft only! Push inner axle in until clip clears inside of passenger spider gear. Set clip aside and push/pull axle shaft straight out to passenger side.
Sometimes even with all of the clips off you have to use an axle puller to "knock" it out. The bearing is in the housing pretty tight. One of the national autoparts staore that starts with letter A has a nice rental/loaner program for that.
when removing the front axle i believe that you must open the front differential cover and inside the dana you will see a small 8mm bolt located on the spider gear center it holds the pin bar in place and the pin bar holds both the upper and lower gears in place with a small washer below them. be careful when you pull the pin bar out to make sure the gears stay in place (upper and lower) do not let the washer fall out of the spider cage assembly. Then, carefully slide the U pin that holds the axle in (there are two of them one for the left axle and one for the right). Once the U pin slides off the axle the axle should slide all the way out of the whole differential - Note if the U pin you see at the end of the axle does not come off easy just push the axle IN ward towards the center of the differential and then slide it out with a small screw driver ..
On the rear differential there will either be a metal plug or a rubber plug. The metal plug can be removed with a 3/8-inch drive ratchet. the rubber plug can be removed with a small screwdriver. Faceing the axle from the rear will see the plug to the right side on the cover plate. Remember to also check the front differential as well. Hope this will help you.
remove front wheel brakes,rotors, axle nut,remove the four bolts on the bake side of your unit bearing using one of the 4 bolts removed from the unit bearing (also knowin as wheel bearing) go get a half dozen of the same bolt only 1 to 2 inchs longer theard them into the unit bearing from the back side and start beating. the unit bearing is a sob to get out but will come out with time once you get it out pull out your axle shaft replace the ujoint and reassemble anti seize everything as you re assemble it
to remove the axles, remove brake caliper and disc, remove hub assembly, the center hub/axle nut and...(there are i think 3-4 bolts on the back side of the spindle to remove the hub), you may have to force the hub off the spindle with a hammer or air hammer... once the hub is out the axle should slide out of the front differential allowing access to the ball joint nuts for removal...
There's not really a best way. If the axle half shafts bolt to the housing just drop it right out. If not you'll have to remove both half shafts from the wheel hub. Disconnect the drive shaft, and drop it out.
