Need diagram of front suspension . im replaceing a lower ball joint on my 1996 sable. my repair manuel is useing words i dont understand like spindle

A more comprehensive description would have been helpful - you know what you mean but in order for us to fully understand the suspension type and system and the problem you need to paint an accurate picture with words.

Wherever possible the manufacturer designs the suspension with the maximum safety in mind so the only way a ball joint can pop out of a suspension arm is where there is damage or replacement has been botched.

Do you mean the ball pin is popping out of the joint? If this is what is happening the joint is damaged or worn out and immediate replacement is necessary.

According to Autozone.com, you must replace the whole control arm. Here is their procedure:
NOTE do not begin the removal procedure unless a new strut-to-lower arm nut, a new ball joint pinch bolt/nut and a new lower arm-to-front subframe bolt/nut are available.

1. Remove or disconnect the following:
   NOTE
   Do not use a hammer to separate the ball joint from the front wheel hub and spindle.

2. Place the steering wheel in the unlocked position.
   NOTE
   Do not allow the halfshaft to move outward. Over-extension of the halfshaft joint could result in separation of internal parts, causing failure of the halfshaft joint.
   
3. Remove or disconnect the following:

You'll need the repair manual for this. There are upper and
lower ball joints front and rear. You also have to deal with
a number of suspension components to access the ball
joints. Lower ball joints can be replaced by pressing old
out and new in using a large socket to match circumference
of the ball joint.

Upper Ball Joint Removal & Installation Ball joints on this vehicle are an integral part of the control arm. If the ball joint is defective, the entire control arm must be replaced.

Upper Control Arm Removal & Installation

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Remove or disconnect the following:
   • Wheel and tire assembly
   • Brake disc shield
3. Use a jack to support the front suspension lower arm.

6. Separate the ball joint from the front wheel spindle
7. Remove the front suspension upper control arm.

To Install:

1. Installation is the reverse of removal. Align the marks made during removal on the front suspension upper arm adjustment cam. The forward front suspension upper arm nut must be tightened first while the arm is held at the curb position ride height.
2. Observe the following torques:
   1. Control arm attaching nuts: 98 ft. lbs. (133Nm)
   2. Pinch bolt: 46 ft. lbs. (63Nm)

For Lower & Upper Ball Joint Step by Step :

For That you use a C-clamp style ball joint press to remove the ball joint from the suspension arm-note the location of the receiver cup ! For installation of the ball-joint, use the same tool when pressing the ball joint into the suspension arm-again, note the location of the receiver cup.

Step by Step :

1. Raise and support the vehicle safely, with jackstands.
3. Remove the spindle and the ball joint assembly from the vehicle.
5. Remove the snapring from the ball joint. Using a ball joint removal tool, remove the ball joint from the spindle. Do not heat the ball joint or the axle to aid in removal.

   Please Rate, Thank you !

Your going to have some tension on the lower control arm, so be aware if the danger. When i replaced the ball joints on my Jimmy, i had it up on a stand and then placed the jack under the control arm to support it so i can let it down slowly.
Once the new ball joint is in place, i used the jack to bring up the control arm again to line it up with the spindle to put the front suspension together again.
Thank you for using Fixya and be safe.

The front suspension on this car should have struts, which means it will have two ball joints, one on each side. They are in the lower control arm, they connect the front bearing spindle to the lower control arm. They can be difficult to replace, some are bolted and some are press fitted. Any reputable front end alignment shop can replace these, but the cost for doing the job will be more expensive for the press fit ball joints. Hope this helps, let me know.

part of lower arm assembly only.

Installation
