02yukon i cannot get the cv joint out from the wheel/brake assem

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.

1. Raise and support the vehicle safely.
2. Remove the front wheels.
3. Insert a steel rod into the brake rotor to prevent the rotor from turning and loosen the axle wheel hub nut. Discard the nut.
4. Remove the ball joint-to-front wheel knuckle retaining nut. Drive the bolt out of the front wheel knuckle using a punch and hammer.
5. Remove the front brake anti-lock sensor and position it out of the way.
6. Separate the ball joint from the front wheel knuckle using a prybar. Position the end of the prybar outside of the bushing pocket to avoid damage to the bushing.

Use care to prevent damage to the front wheel driveshaft joint boot.

1. Remove the stabilizer bar link at the front stabilizer bar.

Make sure the CV-joint puller does not contact the transaxle shaft speed sensor. Damage to the sensor will result.

1. Install a CV-Joint Puller (T86P-3514-A1) or equivalent between the inboard CV-joint and the transaxle case.
2. Install a CV-Joint Extension (T86P-3514-A2) or equivalent into the puller and hand-tighten.
3. Using an impact slide hammer, remove the driveshaft from the transaxle.

Do not allow the front wheel driveshaft and joint to hang unsupported. Damage to the front wheel driveshaft joint may result. Do not wrap wire around the front wheel driveshaft joint boot. Damage to the boot may result.

1. Support the end of the driveshaft and joint assembly by suspending it from the chassis using a length of wire.

Never use a hammer to separate the outboard front wheel driveshaft joint from the wheel hub. Damage to the outboard front wheel driveshaft joint threads and internal components may result.

1. Separate the outboard front wheel driveshaft joint from the wheel hub using a Front Hub Remover/Replacer (T81P-1104-C) or equivalent. Make sure the hub remover adapter is fully threaded onto the hub stud.

Do not move the vehicle without the outboard CV-joint properly installed, as damage to the bearing may occur.

1. Remove the front wheel driveshaft and joint assembly from the vehicle.

To install:
Do not reuse the retainer circlip. A new circlip must be installed each time the inboard CV-joint stub shaft is installed into the transaxle differential.

1. Install a new retainer circlip on the inboard CV-joint stub shaft by starting one end in the groove and working the retainer circlip over the inboard shaft housing end and into the groove. This will avoid overexpanding the circlip.

A non-metallic mallet may be used to aid in seating the retainer circlip into the differential side gear groove. If a mallet is necessary, tap only on the outboard CV-joint stub shaft.

1. Carefully align the splines of the inboard CV-joint stub shaft housing with the splines in the differential. Exerting some force, push the inboard CV-joint stub shaft housing into the differential until the retainer circlip is felt to seat in the differential side gear. Use care to prevent damage to the inboard CV-joint stub shaft and transaxle seal.
2. Carefully align the splines of the outboard front wheel driveshaft joint with the splines in the wheel hub, and push the shaft into the wheel hub as far as possible.
3. Temporarily fasten the front disc brake rotor to the wheel hub with washers and two lug nuts. Insert a steel rod into the front disc brake rotor and rotate clockwise to contact the front wheel knuckle, to prevent the front disc brake rotor from turning during front wheel driveshaft and joint installation.

A new front axle wheel hub retaining nut must be installed.

1. Manually thread the front axle wheel hub retaining nut onto the outboard CV-joint stub shaft housing as far as possible.

A new bolt and nut must be used to connect the front suspension arm to the knuckle.

1. Connect the front suspension lower arm to the front wheel knuckle. Tighten the nut and bolt to 40-55 ft. lbs. (54-74 Nm).
2. Install the front brake anti-lock sensor.
3. Connect the front stabilizer bar link and tighten to 35-45 ft. lbs. (47-65 Nm).

Do not use power or impact tools to tighten the hub nut.

1. Tighten the front axle wheel hub retaining nut to 157-212 ft. lbs. (213-287 Nm).
2. Install the front wheels and lower the vehicle.
3. Using the recommended type of fluid, fill the transaxle to the proper level.

I would have the cv axle changed along with any integral parts such as the abs ring.

REMOVAL & INSTALLATION

1. Disconnect the negative battery cable.
2. Remove the wheel cover/hub cover from the wheel and tire assembly, then loosen the lug nuts. Fig. 1: After removing the wheel/hub cover, loosen the lug nuts
   
   
3. Raise and safely support the vehicle, then remove the wheel and tire assembly. Insert a steel rod in the rotor to prevent it from turning, then remove the hub nut and washer. Discard the old hub nut. Fig. 2: Before removing the hub nut and washer, insert a steel rod in the rotor to prevent it from turning

To remove the cv joint/transaxle, first remove the wheel. Remove the brake caliper and pads. Be sure to tie up the brake caliper to keep out of way. Once the caliper is removed, slide the brake rotor off. Remove the center cap over hub (if capped). Remove the kotter pin and nut hold shaft in place. There are two bolts on the back side that connect the strut to the wheel hub. remove those bolts. Keep in mind that they are not the same size, the bolt heads are angled. To make sure you put the right bolts in place, Take two envelopes and mark top on one and bottom on the other. I had an 89 Horizon (same as Omni), so I did the same with the envelopes. Separate the strut from the hub assembly. Next, while pushing in on the cv joint, carefully pull hub assembly out and turn either left or right. Once you have remove the shaft from hub, using a pry bar, insert pry bar between tranny and axle and pop out. It is that easy. Let me know if there is anything else you may need help with.

In order to change the cv joint, you will need to remove the wheel and the brake caliper and rotor. Raise vehicle on jack stands. Remove the wheel and remove the brake pads and caliper. Tie the caliper up out of the way, do not disconnect the brake line attached. Once the caliper is removed, slide the rotor off. Using the correct size socket, remove the nut in center of hub. Some vehicles have a kotter pin in the shaft just in front of nut. If so, remove pin before nut. Next, you will need to loosen a few bolts that hold the strut to the hub assembly. Once you have hub free from strut, turn the hub either left or right while having someone push in on the cv joint while turning joint left or right. Doing so will allow the joint to slide out of hub. Next, using a pry bar, insert between end of transaxle and transmission and pry out. To install new axle, align the axle with transmission and slide into transmission. Carefully work the other end of axle into the center of the hub assembly. Once you have it in the hub, tap gently with a rubber mallet until you hear it "pop" into transmission. Once it is in transmission, replace the bolts connecting the hub to strut. Replace nut on center or cv joint and tighten just until it seats against the hub...do not overtighten. Replace kotter pin with new pin. Slide the rotor over the studs, replace caliper and brake pads, install wheel and you are done.

If you know for sure it is not the brakes, then the other 2 options are the bearing in your drive shaft hub, or the drive shaft CV joint assem.
Really the only way to tell is put it up on safety jack stands with the park brake on, and rear wheel chalked, remove the front wheels and have someone listen while you put the car in drive. Let the drive turn slowly at idle and see what you find.
Please let me know what you find

u need 35mm nut socket to remove wheel nut then remove brake caliber and rotor then you to with a gear puller pull the wheel axle from cv shaft ,then remove upper and lower ball joint nut with ball joint fork start banging with hammer or airtools

Raise vehicle up on jack stands so that the stands are under the lower controll arms and the suspension is "loaded" Remove the front tire(s) (if you break the torque on the nuts while the wheel is still on the ground it helps, but do not loosen them completely as you will be looking for new rims and wheel studs too). Place a drift or some other suitable object in one of the brake rotor vanes so that it will hit the brake caliper and stop the rotor from moving and remove the CV shaft nut (it's a big ****** make sure you have the right socket on hand before getting to this point). Next remove the brake caliper and rotor then undo the wheel bearing retaining bolts and remove the wheel bearing. This should give you enough room to move the axle shaft back and up so you can work on the ball joint. If you've had ball joints replaced before just unbolt the ones that are installed and using a pickle fork, or a block of wood and a hammer, drive the ball joint stud from the knuckle. (make sure to support the upper control arm so it doesn't drop down on you when you do this) If you are working on original ball joints then I reccomend placing a block of wood or something else that will protect the cv boots from drill bits ect and drill out the rivets holding the ball joint in place. then remove in the same manner indicated in the previous paragraph. installation is pretty much the reverse of removal and don't forget to torque your cv shaft nut I have a 1999 and the manual specs 103FTlbs... This is a critical torque as it helps preload your wheel bearing. Too high and you'll burn them up, too low and they'll be loose and wear out.

you have to replace bearing and hub as a unit.you have to remove remove brakes and caliper rotor set them aside dont disconnect brake line. get a piece of clothes rack wire to hold brake caliper .do not let it hang by brake hose. you got to remove hub nut. best way to do that is loosen it a litttle while tire still on weight of car keep wheel from turning .

1) Remove wheel.. 2) Separate Tie rod and lower Ball joint..3) Remove Axle Nut.. Leave Brakes and Rotor in place.. 4) wire or tie to get the assy. outta the way.. The rest should be easy
