The right side inner cv joint cup is wobbley, is it the cv joint or a bearing on the transmission? Thank you

To remove an inner CV joint, you must remove the entire half-shaft from the vehicle. Here is the procedure:

1. Before servicing the vehicle, refer to the Precautions Section.
2. Remove or disconnect the following:
   
   Front wheel Spindle nut Lower ball joint from the knuckle
3. Press the stub shaft out of the hub, use a plaster hammer if necessary.
4. If removing the left side halfshaft:
   1. Using a suitable pry bar, pry the inner joint out of the transaxle.
5. If removing the right side halfshaft:
   1. Using a suitable pry bar, pry the inner joint out of the center bearing bracket.
   2. Remove the center bearing bracket mounting bolts.
   3. Using a suitable pry bar, pry the center bearing bracket from the cylinder block.
   4. Remove the inner shaft from the transaxle.
   
   
   The individual joints CAN be replaced, but this requires disassembly of the half-shaft by cutting the clamps that hold the boots and frankly is a greasy mess. Remanufactured half-shafts are available for less than $100 USD and are already assembled for immediate installation.

The left axle is a little tricky I use a crow bar and tuck the curved end in behind the cup of the axle then look for a good sturdy position on the transmission and do a quick snap on the crowbar and the axle pops out. Be ready with an oil pan if you did not drain the transmission oil as it will come out. Also Saturn transmissions get serviced with dexron III even the manual transmissions. When reinstalling the new axle place the transmission end in first and get the snap ring to hold before re-assembling the rest of it. Is best to insert the end of the axle into the transmission, then hold the axle straight while pushing inward on the axle until you feel the cv joint bottom out inside the cup then with a dead blow hammer, strike the outer end of the cv joint and you should be able to feel the inner snap into place. To make sure that it is reach in and grab the inner axle you should not be able to pull it back out by hand. If you try to hammer on the inner cv joint during installation you take the chance of damaging the boot. And causing premature failure of the inner axle cv joint. Hope this helps.

It is easier to change the whole half shaft than it is to change just the CV joint.

how to , who can, what are all steps. are there special tools?
sure. if the boot is bad, so be the joint, Yah think?

1. Before servicing the vehicle, refer to the Precautions Section.
2. Remove or disconnect the following:
   • Halfshaft from the vehicle
   • Snapring and bearing
   • Snapring and oil seal
   • Mounting bracket
   • CV-joint boot
   • Circlip and inner joint housing
   • Snapring and spacer
   • Inner joint balls
   • Snapring and inner CV-joint
   • To install:
     
   • Install or connect the following:
     
     • Inner CV-joint and snapring
     • Inner joint balls
     • Spacer and snapring
     • Inner joint housing and circlip. Add 150 grams CV-joint grease.
     • CV-joint boot
     • Mounting bracket
     • Oil seal and snapring
     • Bearing and snapring
   • Install the halfshaft and mounting bracket to the vehicle.
   • Check the wheel alignment and adjust as necessary.

CAUTION: It is advisable to get this job done by a qualified technician otherwise you will take the consequences.
Do the following job at your own risk.
- Place the car on a level floor.
- Pull up the hand brake.
- Block the rear wheels with wheel stoppers, wooden blocks or bricks.
- Call a friend or relative to depress the foot brake, turn the steering wheel little towards left side and put the car in 4th gear.
- Loosen the axle nut force fully (large one in the center of wheel) with a socket and double extension rod.
- Loosen the four wheel nuts.
- Lift up the front left wheel with Jack, place a support under the strong chassis and remove the jack.
- Remove all the wheel nuts and remove the front left wheel.
- Place a container or tray under the inner CV joint to preserve the transmission oil which will come out unavoidably during the axle removal.
- Remove the lower ball joint nut.
- Remove the tie rod end.
- You don't have to remove the hub completely but to release it a little.
- Pull the hub out by pressing the CV joint in and take the outer end of the CV joint out of the hub.
- Place a strong long chisel like lever between the inner CV joint cup and the transmission and push the cup away from the transmission to take the lock out of its host.

It can be fixed but now you will need to remove it from the trans and cut the band off the larger side of the boot. then re-alighn the knuckles and slide the 3 joints in 1 at a time. You going to need a new band and the crimper which you can usualy rent from a parts store that has free tool rental. Make sure you grease the joint before you slide the boot back on. Its easier that it looks. When you pull the cv joint out of the transmission some fluid will come out too so use a drain pan. Sometimes they are a pain to get out but a good prybar and some patients usualy works. Pry as you turn the cv joint and it will pop out. Good luck!

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

I quote from service manual

1 . Raise and support the truck. Remove the rear wheels, the brake drum or brake caliper and rotor. If this is a disc brake, support caliper with wire. Remove seal retainer nuts from axle
housing.

2 . Pull out the axle shaft from housing. Remove the snap ring and bearing race from the axle shaft. Cut the bearing retainer. Break the bearing cage using a hammer and chisel and remove cage and rollers.

3 . Remove the oil seal, the seal retainer and the parking brake assembly (rear). Using a hydraulic press and bearing splitter, press the inner race from axle shaft. Inspect axle shaft for seal wear. Ensure that the shaft is not bent.

it will rotate the slip joint that on the drive shaft into transmission only slides in and to allow ear suspension to work without breaking driveshaft. I would remove driveshaft and inspect front joint. it it does not flex sided to side and up and down, then it is bad. replace and be very careful when pressing in cup that the bearings don't fall out.

with a pry bar or pry between the trany and cv or put the pry bar on the cv and hit it with hammerits just a little c clip holding it good luck pierre
