Usually a bad U Joint - Universal joint connecting drive shaft to transmission & rear drive axle - there is a U joint at each end of the drive shaft - repair this ! Thew drive shaft can actually come off the car when driving - can be very dangerous.
It is a staked joint drive shaft. It is not meant to be serviced.
The axle shaft is retained from the inside with a horseshoe looking clip.The axle shaft is retained from the inside with a horseshoe looking clip.
I believe, perhaps, you mean a splined joint. This type of joint allows a rotating shaft to effectively change length while maintaining rotational speed and location and transmitting rotational forces.Basically, two shafts come together to form a single shaft here. The one shaft has an extension that is round but has longitudinal grooves machined into it. The other shaft has a hole with grooves cut into it as well. The extension of one shaft fits neatly into the hole of the other shaft with the high ridges (splines) of each fitting into the grooves of the other. Typically, grease lubricates the splines and sliding in and out allows the two shafts to act as a single shaft of variable length.AnswerCotter Pin?
It's usually much more inexpensive to replace the entire drive shaft than to repair a worn cv joint. The new drive shaft will come with new cv joints and new boots.
You did not specify yearI am going to guess yours is the pain in the butt one.Remove drive shaftPlace on bench viseIf yours is the one I think the Joints are cast into the shaft with a plastic retainer so you have to CAREFULLY heat up each ear and "U" joint end cap until it melts and runs out. Overheating the ear ruins the shaft or flange so be carefull!WHile it is hot use a hammer to normally beat out the joint cap or your press to press out the joint cap.The replacement joint will come with "C" clips to retain it.
The security light might come on while you are driving because it has a motion detector on it and when it senses the cars movement the light comes on.
Bad inner CV joint?
Probably a dry bearing or worn out bearing. Possibly a bent axle shaft. Have the tire checked for improper balance first, then see about the other possible diagnoses.
You have to pull the bearing assembly out. Be careful and do not let the cap covering the bearings come off.
There are many reasons your check engine light could come on. If your motor died while driving you should check the rank shaft sensor module, alternator and catalytic converter.
It should just come out like the rear shaft, remove the 4 bolts on the front dif and the shaft should just slide out of the transfer case. I have a 98 suburban and it may require a bit of patience getting it around the exhaust pipe which is directly under the shaft.
