1989 s10 front differential i replaced both my cv axles all ball joints and control are bushings and after 100 miles now my right side axle is coming out of the housing? what hols it in the housing

There should be a circlip on the inner joint that holds it in the spyder gear set.

OK so it's your CV axle most likely during slow revolutions it clacks and makes noises so replace both sides to ensure transmission/engine performance stays optimal to power applied to the road. The other cause of noises in that area are due to the wheel bearings needing replaced usually and sometimes repacking the bearings instead. On your car if the axle passes through the wheel it has to ride on something to control balance and torque across the drive shaft. I would replace both front driver and passenger side wheel bearings and the CV axles on both sides please be smart people and replace parts like these in pairs/ together the reason being after you replace one side you drive a few months or less and the other side goes out almost always soon after the other I would say over 75% of the time let it be bearings/u-joints/CV axles or other crucial parts. Hope this helps please take my word and fix it right the first time and please buy the better parts not the cheapest parts out there if you want quality/ safety than buy the better or best parts never just the good or OK parts

It should have been thoroughly checked. Noises like these on four wheel drives could several different things. A bearing, CV axle, or the differential, or bearings in the differential. A wheel bearing will make different sounds when making a turn. A CV axle is a constant sound. Differential bearings can come and go, depending on if it is a bearing for the axle or a pinion bearing. Axle side bearings usually make a constant noise. The differential can also come and go. Depends on acceleration or slowing down. All these sounds are also with a vibration. Slight to harsh.

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.

Jack up car and apply e-brake. car will roll if one of the front tires leaves the ground. remove tire , spindal nut and lower ball joint bolts. remove axle from hub then use a prybar to pop it out of trans. the passenger side will have a braket holding axle to engine , remove bolts from braket or squeeze snap-ring to rmove axle from braket.

Buy the right CV axle. Raise right front of vehicle. Remove wheel. use a lugnut and washers to secure brake rotor so that it is not flopping and trapping rust behind. Remove axle nut. Loosen nuts from outer tie rod end stud and lower ball joint stud almost all the way off, but do not remove them completely. Seperate the studs from knuckles by striking each knuckle with a ball peen hammer. After the tie rod and lower ball joint are seperated from the spindle knuckles, pry down on lower control arm and push end of axle through hub toward transaxle until hub and spindle assembly is free from axle/CV joint. Place drain pan under transmission. Carefully place pry bar between innner CV joint and transmission and pop axle assembly loose. Install new axle in reverse of the dissassembly.

I cannot see it, but I am guessing that you need to replace your axle seal. To do this,you have to pull your CV shaft out. Remove the tire, remove the caliper from the top of the rotor. Using a hammer on the back, remove the rotor. Take off the spindle (axle) nut, separate the axle (CV shaft) from the hub. Replace seal. It should pop right out. Good luck!

Loosening but not removing the strut top mounts and sway barend link bushings can provide a bit more suspension travel for easieraxle removal.
Loosen and remove wheel side axle mounting bolts.
Separate the axle from the wheel. Do not allow axle to hang from thetransmission or differential. Oil seals could be damaged.
Gently pull, pry, or otherwise liberate the axle from the transmissionor differential. Do not bend axle seals. Be careful not to teartransmission or differential oil seals.
The axle splines on the right show damage. Note the c-clip on both axles.
Don't forget to transfer any axle seals, ABS rings, or other parts to the replacement axles.
Guide the replacement axle into place. Depending on the type of retainer, the axle should click firmly in place.
Always use the proper torque on the axle bolts. Check axle rotation. Reassemble dismantled components.
