The details depend on if this is a front or rear axle, if the vehicle is front, rear, or AWD/4WD, and the specific vehicle. None of that information was provide, so the info below will be rather generic.
Typically replacing a CV axle, or halfshaft, involves removing the wheel, then removing the axle nut at the brake rotor. I suggest this step before removing the brake components just in case you need to have someone apply the brakes to get the nut loose. Then remove several brake components at the wheel (caliper, rotor, dust shield, etc), and properly support the caliper to avoid damage to the brake hose. Often you'll then need to remove either a ball joint or the strut from the knuckle to be able to move the knuckle/hub assembly out of the way enough to snake the outer joint out of the bearing. The inner joint may just be slid in place or there may be a little circlip that keeps the inner joint in the transaxle/differential.
In some cases the inner joint is bolted to a stub axle, in other cases the differential may be supported by the inner joint, so know which type you are working with before just blindly pulling things apart.
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.
remove inner cv boot, just on inside edge is circlip which holds inner bearing joint into outer housing remove circlip and separate joint outer housing does not come out of front diff unless you drop or remove whole front diff assembly will have to remove whole stub axle hub assembly to remove drive shaft from outer wheel stub axle (hub) assembly
remove the axle stub retaining nut, disconnect the lower ball joint, disconnect the tie rod end, pull the spindle out and away from the axle stub tapping on the end of the stub if necessary with a hammer (just be careful) to pull the bearing hub loose from the axle stub. after separating the outside slide under vehicle (make sure the car is on jack stands and the rear wheels are blocked from rolling and very secure before crawling under any vehicle) look at where the inside axle stub goes into the transmission. you'll need a good sized pry bar to pop the axle out of the transmission. work the pry bar in between the inside axle stub and a good thick part of the transmission and pry the axle away from the trans., there is a snap ring on the inside axle stub that internally retains the axle you have to pry hard enough to compress the snap ring into the axle groove which will release the axle for removal. it's not a bad idea to replace the axle seal in the transmission while you're there but if it's not leaking and you don't damage it in the removal of the axle it's not necessary. measure and compare the new axle to the old one, it may have some differences in the shaft like missing vibration dampeners but if it's the same length and both axle stubs match the old ones in size and number of teeth you should be good. when you install the new axle line it up by hand and slide it in as far as possible manually then tap it in with a wooden or rubber mallet. if you don't have a mallet use a scrap of wood to protect the new axle stub threads and tap it in with a hammer. after you feel the snap ring collapse and the axle slide in tap on it gently to make sure it's fully seated then grab the inner axle stub and tug on it to insure the snap ring is in place. then reassemble in reverse order of removal making sure all nuts and bolts are tightened properly and all retainers are in place. good luck
Disconnect the vehicle battery ground lead. Support the vehicle at the front and remove the appropriate wheel. Remove brake caliper and disc assemblies see SRO 70 10 Note- Do not allow the caliper to hang by either harness or flexible hose.
Pry off the hub grease cap Remove and discard cotter pin pull off castellated nut retainer Remove the hub nut and bearing washer. Carefully remove the hub assembly from the stub axle.
Pry the original seal from the spigot and discard. remove the bearings and using a drift punch knock out the bearing cups. Remove all traces of grease and dirt from the stub axle and back plate. Note: the backing plate may be used to pull the inner bearing and seal if they stay on the stub shaft. Press in the new bearing cups using a socket or other tool of the correct size to prevent damaging the new bearing cup or hub. Note: Do not use bearing to press in the cup. Pack the annular gaps of the oil seal lips with grease. Wash the hub assembly thoroughly. Ensure that the hub inner seal diameter is free of debris or damage and is lightly lubricated prior to assembly. Only replace complete bearings, never cup or race in isolation. Pack each race with approximately 4 ml of grease and position the inner race onto the stub axle. Apply a smear of grease to hub inner surfaces and bearing cups. Assemble the hub to the stub axle followed by outer race, bearing washer and hub nut. It is not necessary to fill the hub cavity with grease, merely protect from corrosion with a coat of lubricant. Seat the bearings by slightly tightening the hub nut whilst rotating the hub. Do not apply load without rotation.
Adjust End float. Set a Dial Test Indicator and adjust the hub nut to achieve the correct end float. .001-.003" As the adjustment is made, continually load the hub axially in both directions. Without disturbing the end float setting, fit the castellated nut retainer so that it aligns with both hub nut and stub axle drilling. Secure nut retainer using a new cotter pin.
Reassemble brake rotor and caliper. Bolts MUST be tightened to specification operation of the braking system verified. Reassemble wheel
raise you vehicle on jackstands. remove front wheel and tire.remove front caliper from steering knuckle assembly, remove rotor from hub by pulling it staright off. remove speed sensor bracket from strut assembly. remove hub and bearing to stub axle retaining nut. dislodge inner CV stub shaft retaining ringon transaxle assembly. insert small pry bar between transaxle case and inner CV joint by prying on it.remove strut assembly to steering knuckle bolts remove top of steering knuckle from strut assembly, then rotate CV assembly out of vehicle. Remove inner shaft from transaxle stub shaft grasp inner CV joint and interconnecting shaft and pull both pieces out at the same time. good luck!
The simple answer is YES. You will need to remove brake
drum / hub and inner and outer wheel bearings. This allows access to the
Although a little tricky___You should now be able to install a new stub
axle, without removing the brake shoes or Handbrake cable
remove inner cv boot, just on inside edge is circlip which holds inner bearing joint into outer housing remove circlip and separate joint outer housing does not come out of front diff unless you drop or remove whole front diff assembly
will have to remove whole stub axle hub assembly to remove drive shaft from outer wheel stub axle (hub) assembly
