State inspection man said I needed Upper Ball Joints on my 95 Mark VIII Lincoln and I said are you sure it's not the Upper Control Arm Bushing? He said ahhh I think you have to do both. Is this true or do you think it was just the Control Arm Bushing and how can I check to find out if both. Do I need special tools?

Re: Upper control arm bushing and upper Ball joint
Dealer only or general mechanic to change these parts not really a do it yourself job .do you have a two ton jack ??? or the metal plates in floor to move the suspension to check it ---no take it to a garage trust me it will be cheaper and quicker in the end .you leave something loose or incorrectly fitted and with this heavy lump of detroit steel you could kill a lot of people .

jack up and support vehicle grab top and bottom of wheel and see if its loose if loose feeling up top or clunking possible upper ball joint if bottom feel/noise poss bottom ----move wheel side to side and look and check tie rods if loose or noise inspect and replace if damaged or worn ---remove wheel and inspect the joints and tie rods if their was no noise or worn check the upper and lower control arm bushings as well as the swaybar supports and bushings
You probably should replace the whole upper control arm. I don't believe that you can separate the ball joint from the control arm without damaging it and the ball joints are not listed separately for sale. [If the ball joint is bad, the bushings can't be in very good shape, either.]
To replace the upper control arm, you need to take the weight off the spring and pop the ball joint out of the spindle with a special tool OTC 6297 Ball Joint Separator
Then it is bolted in by the 2 pivot bolts [#3 in the diagram].
Where you buy your ball joints usually will rent (for free, just pay for it and then return it is what they do) a ball joint press. It's an easy job if you have any mechanical skills at all. The strut is what keeps the pressure on the spring, using the weight of the vehicle to compress the spring, just undo the strut, raise vehicle and the spring will relax and you can remove the upper control arm.
Before servicing the vehicle, refer to the precautions in the beginning of this section.
Remove or disconnect the following:
Wheel and tire assembly
Brake disc shield
Use a jack to support the front suspension lower arm.
Mark the position of the front suspension upper arm adjustment cams.
Remove the upper ball joint retaining nut and pinch bolt.
Separate the ball joint from the front wheel spindle
Remove the front suspension upper control arm.
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.
REMOVAL AND INSTALLATION
Upper ball joints are not replaceable. The upper ball joint is part of the upper control arm bushing joint and is not serviced separately. If the upper ball joints are found to be defective, the entire upper control arm bushing joint assembly must be replaced.
Lower Ball Joint
Support the vehicle in normal driving position with ball joints loaded.
Wipe the grease fitting and checking surface, so they are free of dirt and grease. The checking surface is the round boss into which the grease fitting is threaded.
The checking surface should project outside the cover. If the checking surface is inside the cover, replace the lower arm assembly.
Since the new arm comes with the bushings, there is no reason to get the tool to install them. Upper arms are relatively easy to install...just a bolt out, bolt in operation as the springs aren't involved. Support the suspension under the lower control arm to take any tension off the upper arm.
I've done front end work. You may need a ball joint press, to remove the lower ball joint off the lower control arm and install or press the new one on. The upper ones you will have to chisel the the tops of the riviets off and drill though them unless they're on with nuts and bolts. It is easier to have the upper control arm off the car to do this also because the upper control bushings may need replacing also. You can get those off with a air chisel and on with a vise and a 5 pound sledge hammer and a sleeve on the bushing.(They make a bushing press which is better.) If you don't have air take the upper arms to a muffler shop. Before I had air, I took my arms to a local tire shop, he took the old ones off and put the new ones on for $20.
upper ball joints are really easy, but you can't buy them without the a-arm, I just did one if the a-arm bushings are ok, just change out the ball joint and bracket, lower ball joint is harder, but I will help you if you need it
