I performed this work with the Lower Control Arms completely removed from the car. It is possible, and might actually be easier, to do this work with the LCAs installed. This would use the car to hold them steady as you pressed out and pressed in the ball joint. Oh well, live and learn.

Tools Required:
Ball Joint Press
7/8" Socket
24mm Socket
21mm Socket
18mm Socket
15mm Socket
Lug Nut Socket
1/2" Large Drive Ratchet, Breaker-bar, Impact gun, or equivalent.
Snap Ring Pliers
Flat Head Screwdriver
Beer

Parts Required:
Replacement Ball Joint w/ Boot
Replacement Pinch Bolt (DO NOT reuse old bolt)
Grease Gun w/ Grease

Remove Lower Control Arms:
Follow the first 5 steps of uncommon©'s LCA Bushing install How-To for removing the Lower Control Arms. Pictures are located in his thread How-To: Install Solid LCA Bushings

Step 1: Jack up the car & use jack stands. Then remove the wheels.
Step 2: Remove the bolt that holds in the VERTICAL BUSHING using a 24mm socket
Step 3: Remove the bolt that holds in the HORIZONTAL BUSHING using a 21mm socket
Step 4: Remove the bolt & nut for the ball joint (where it connects to the knuckle) using an 18mm socket for the nut and a 15mm on the bolt. After removing this bolt the LCA will no longer be bolted to the car and should be removed.

Remove Ball Joints:
Step 1: Open Beer (Repeat as necessary)


Step 2: Remove worn ball joint boot using the end of the flat head screwdriver








Step 3: Clean off ball joint surface with a shop towel.


Step 4: Assemble ball joint press pushing the ball joint down through the LCA (If you do it the wrong way, it wont budge...don't ask me how I know...)









Step 5: Once assembled use your 7/8" socket and 1/2" drive ratchet/breaker-bar/impact to tighten the press down on the ball joint




Step 6: Continue to tighten, the ball joint will begin to slide out of the LCA


Step 7: Once the ball joint is free, it'll all probably fall the to the floor...like so.


Step 8: Admire the old ball joint.

Ball Joint Install:
Step 1. Locate new ball joint.
MOOG PN K7147




or Mopar PN 04656010AE and 04656464AA






Note: The MOOG ball joints come with the boot, ball joint, and pinch bolt. They also have a grease fitting so that the ball joint may be regreased later. The Mopar ball joint, boot, and pinch bolt must all be ordered separately. I do not know the PN for the pinch bolt. I happened to have both parts here, but will be continuing this How-To using the MOOG ball joints. I will also continue assembling the ball joint with the LCA installed into the vehicle. Follow the above mentioned How To for instructions to reinstall the LCA.

Step 2. Install the ball joint from the underside of the LCA


Step 3. Assemble the press so that it pushes the ball joint up through the opening in the LCA. My particular press' plates are slightly different so make sure you put the correct one on each side.




Note: After installing the press as show above, I noticed it would be easier to get my impact gun on it if I flipped it upside down. Your mileage may vary.


Step 4. Tighten press using impact gun, 1/2" ratchet, or breaker bar


Step 5. Continue to tighten the press and make sure the ball joint installs straight and completely into the arm




Step 6. Install included snap ring using snap ring pliers.




Step 7. Using an adjustable wrench, rotate the ball joint so that the notch cut out is parallel with the vehicle and will line up with the bolt hole in the knuckle

Step 8. Install knuckle, and new pinch bolt and nut. Torque to 70 ft/lbs.

Step 9. Install grease fitting, taking care not to over tighten, and pump ball joint with your favorite grease.

not that long, honestly. With the LCAs off the car it was pretty quick.

i actually have one, but it was getting late and my compressor is pretty loud.

how do you reinstall the LCA? i cant get the vertical or horizontal hole back in place because of the springs pusing down on the spindle.
