Axle shaft seal replaced,did not look like the axle went fully into the trans is this normal? the ca runs and doesnt seem not normal

you have to pull the half shaft out on the side the seal is leaking then pop out the seal and install new seal. this means r&r the wheel, brake, separate the lower ball joint, remove the half shaft axle nut, remove the half shaft from the spindle and pull out half shaft from trans. install in reverse order.

are u talking about the front main seal? if so ,yes u have to take the trans. out to replace

The seal you need is called a transmission/transaxle output shaft seal. The 2 best things to do, either get the number off the original seal and have it matched at a local autoparts store or go to Kia/Hyundai. they will know the proper seal. Be sure to install the seal evenly into the trans or it may leak again. If you need anything further, please let me know.

Axle Shaft Bearing & Seal Removal & Installation To Remove:

1. Raise and safely support the vehicle.
2. Remove the axle shaft.
3. If replacing only the seal, remove the seal using a suitable seal removal tool.
4. If replacing the seal and bearing on the 8.6 inch axle, install the slide hammer and adapter behind the bearing and pull out the bearing and seal together.
5. If replacing the rear axle shaft seal and the bearing on the 9.75 inch axle, install the J 29712 or equivalent bearing puller into the axle housing behind the axle bearing.
6. Remove the axle shaft seal and the bearing by tightening the nut on the J 29712 bearing puller.

Use a slide hammer, bearing puller and adapter to remove the old axle bearing

To Install:

1. Install the axle shaft bearing using a suitable size driver. Drive the bearing into the housing until the tool bottoms against the tube.
2. Lubricate the seal lip and install the seal with a suitable seal driver. Make sure the seal is fully seated in the axle tube.
3. Install the axle shaft.
4. Fill the rear axle with the correct lubricant.
5. Lower the vehicle.

GM went to a "fill for life" transmission on these cars, easiest way to tell is look at the top of the trans, you shoud see a red screw on cap about 1.5 inches across. If you have this, the proper way to check the fluid level is to run the car to normal operating temperature, raise the vehicle on a hoist and while the engine is running in park, remove the check plug on the right side of the transmission by where the axle shaft goes in. When you are looking at the axle, it will be a pipe plug at about the 4:00 position. Some trans fluid will run out. Add fluid until it starts running out the hole. When it stops, reinstall the plug and you are at the proper level.

I assume you mean trans axle seals in front.
You have to remove the drive axles,best done on a lift,not in your driveway.
Trans fluid lubes the Diff,that is in trans.
ATF4 etc,whatever the fluid replaced the original spec, when it was new.

Generally the trans pan is first to leak on any transmission. If the perimeter of the pan espeacially the mounting bolts are wet with red fluid change the filter and gasket. Add transmission fluid as recommended in the owners manual also
If the leak is between the engine and the trans the front pump seal or pump seals need replacement.
If leaking at the axle shafts the axle seals need replacing

When you say you can hear the bearings, I wonder what you are hearing. If it only started from doing the seals, I would go back in and see if something is rubbing. Bearings don't go bad quickly.

Yes it's a bad seal and most likely the side bearing to the trans axle is bad too. Once the bearing has play, it vibrates and causes the oil to leak though the seal. Note: if one side went bad the other side is soon to follow since they have the same amount of miles on them. Might as well change both side. Good luck and hope this helps. Keep an eye on the transmission fluid level, don't want to burn out the transmission.

The beaings job is to not only give the axle something to rotate on, but also the keep the axle centered in the hole. When the bearing gets loose, it allows the axle shaft to have an oblong roation, which wears on the seal and allows it to leak. You don't have to run the trans low on fluid to have the output bearings go bad. If you have gone enough miles to wear out a clutch, you have gone enough miles to get some play in the bearings.
