It should have a bolt through a pin holding it in place inside the diff cover. Remove the cover, find the small bolt going through the pin, remove the bolt and pin, and push inward on the axle from the hub. The retainer clip should fall, allowing you to pull the axle shaft out.
Good luck!

hi there, i have 2 mazda6s, both off which i needed to removed the inner axels on, so far you have done every thing right :), but unfortunatly due to mazdas sloppy assembly the inner axles are near impossible to remove, you could try getting a 2 or 3 legged puller and remove the brake calliper and disk then try and "pull" the shaft out, but unfortunatly i doubt will work. your second option would be to use a hydraulic ram to press it out, but again due to mazdas sloppy work it is near impossible with out damaging the hub, ive tryed both option and none of wich worked, so i brought 4 second hand hubs and outer C.Vs, hope this helps.

    Rear Axle


    inside the rear end,you need to remove the rear inspection cover from the rear end.have it jacked up and blocked for safety,and put it in neutral,you will see a slide bar in the center of the rear end it goes in between the side gears.rotate the drive shaft around until you see the end of the round slide that has a 5/16 bolt going thru it. loosen that bolt but don't remove it yet,rotate the drive shaft until the slide bar is almost down at the bottom,but just enoughup to be pulled out and clear the housing.use your left thumb to hold slide bar from falling out while you remove the 5/16 bolt,now let the slide bar fall out to you while your pulling on it.
    "VERY IMPORTANT"= don't let any one turn any rear wheels while the bar is out or you will sping the spider gears right up and out of the rear end.
    Now have someone push the axle in towards you,when they do a C clip will fall of the axle,you will need to recover it with your fingers or a magnet ,You can now pull the axle out,you will see the groove the C clip was in,When you reinstall push the axle in onlt try not to turn it,you might have to a little to line the splines up,when the axle is pushed in the whole way,insert the C clip and you hold it there while someone pulls outward on the axle that will put the C clip in it's seat,then reinstall the slide bar,you may have to wiggle it a little or just barely turn the drive shaft to get it to go in,reinstall the 5/16 bolt and tighten,install new cover gasket and refill.good luck

    Removal of broken axel broke of by wheel


    not a problem,
    jack up your car and block it on side frames,you need to have room to work at rear pun-kin,get a pan for rear gear lube to drain in,remove the bolts on the rear of the housing,yours I think should have 12 holding on inspection cover,When you have removed cover,put car in neutral so you can turn the drive shaft,you will see side gear on left and right,in between those side gears is a round shaft ,turn the drive shaft around until you see at one end of that shaft is a 5/16 bolt holding the shaft in .Ok here comes the part you must be very careful!!!!!!
    loosen the 5/16 bolt completely but don't pull it out yet,turn drive shaft until the shaft and bolt are pointing down where the shaft will be able to just clear the housing,ok now hold the pin from falling out with your left thumb and remove the bolt with your right hand,
    let the shaft come completely out,
    "most important" Don't let anyone turn any of the rear wheels or it will spin the spider gears right up and out!!!!!
    Go to the broken axle side of the car or have someone who is helping do it,have them push the axle shaft in towards you,if your watching the axle being pushed in you will see a big horseshoe clip fall down,that is all that holds GM axles in!
    once the clip falls you can push the axle out some with your fingers and pull it the rest of the way out,
    when you reinstall your new axle you need to get that horseshoe clip that fell,insert the axle without turning it,push in it as far as it will go,then you slide the horseshoe clip in the grooved out spot on the axle,hold in in place while someone pulls the axle out where clip will seat it's self,now slide shaft back in with bolt hole on bottom,you may have to wiggle it a little,when you have it in far enough to get the bolt back in go ahead and tighten the bolt,the rest is cleaning the cover gasket off and installing a new one and tighten all the bolts the same and refill,don't forget to put your car back in park before you let it down,
    good luck

    HOW DO YOU TAKE THE DRIVE SHAFTS OFF A 2002 DODGE DURANGO


    To remove the drive shaft you will need to raise the vehicle off the ground and support it with jack stands. There are 4 bolts that hold the rear drive shaft u-joint in the pinion yoke on the rear differential. Once you remove the bolts and u-joint straps, then just carefully pry the u-joint from the yoke. Be careful not to let the u-joint caps slip off of the u-joint or you could lose the needle bearings that are in the u-joint caps. Once you have freed the shaft at the rear you can just slip the drive shaft rearward to remove it from the transmission. Place a drain pan under the transmission where the drive shaft is connected, as transmission fluid will run out, and you don't want it dripping on the ground. If you vehicle is four wheel drive and you want to remove the front drive shaft, you remove it just like the rear shaft but there are bolts and straps on both ends of the front one. You will probably need to keep the front shaft from turning while you loosen the bolts. You can use a long screwdriver or pry bar inserted in to the area between the u-joint and the yoke.

    If you have that much play in the pinion, your pinion is getting worn, or the nut is loose. You may be able to find a rear end at an auto wrecker cheaper than anything.

    Is this a 9" inch rear end? if so unbolt the axles from from the out side behind the brakes and pull them out, then remove the drive shaft rear u joint saddles and drop the drive shaft down, remove all the bolts from the differential carrier on the drive shaft side and drop out the rear end unit, be careful it is very heavy and the ring gear teeth can really cut u up.
