To replace the lower control are you need to unbolt it from the subframe, airmatic strut, sway bar link and from the lower ball joint. The lower ball joint is separate from the lower control arm. The ball joint actually gets pressed into the steering knuckle. Then the lower control arm sits on top of the ball joint and gets bolted down. The lower control arms list price are about $330 each and the ball joints are around $78 each for oem mercedes parts. The total labor for both to be replaced is somewhere between 6-8 flag hours. The thrust arms are also part of the front suspension and those arms are one piece that have a ball joint as part of the arm. The lower control arm usually doesn't need to be replaced unless its damaged since the control arm bushings are available separately and are around $73 each side for the kit.

Ball joint repair and how do you do it

To perform the following procedure, the lower control arm must be removed from the vehicle. Refer to Removal And Installation for that procedure.

  1. Using a screw driver or other suitable tool, pry the seal boot off of the ball joint assembly
  2. Position receiving cup, Special Tool 6758 to support lower control arm when removing ball joint assembly. Install Remover, Special Tool 6919 on the top of the ball joint assembly.
  3. Using the arbor press, press the ball joint assembly completely out of the lower control arm.

NOTE: When installing ball joint in lower control arm, position the ball joint in control arm so notch in ball joint stud is in the direction shown. This will ease assembly of the ball joint to the steering when installing pinch bolt.

  1. By hand, position ball joint into ball joint bore of lower control arm. Be sure ball joint is not cocked in the bore of the control arm, this will cause the ball joint to bind when being pressed into control arm.


  1. Position control arm with installed ball joint, in an arbor press with Receiving Cup, Special Tool 6758 supporting the lower control arm. Then center Installer, Special Tool 6908-4 on the bottom of the ball joint
  2. Carefully align all pieces. Then press the ball joint into the lower control arm until it is completely seated against surface of lower control arm. The ball joint is correctly installed when there is no gap between the ball joint and the lower control arm. Do not apply excessive force against the ball joint or the lower control arm.
  3. Install a NEW seal boot by hand as far as possible on the ball joint. Installation of the seal boot is to be with the shield positioned as shown.

CAUTION: Do not use an arbor press to install the sealing boot on the ball joint. Damage to the sealing boot will occur if excessive pressure is applied to the sealing boot when it is being installed.

  1. Place Installer, Special Tool 6758 over seal boot and squarely align it with bottom edge of seal boot. Apply hand pressure to Special Tool 6758 until seal boot is pressed squarely against top surface of lower control arm.

CAUTION: A replacement ball joint is not pre-lubricated. Properly lubricate the replacement ball joint using Mopar Multi-Mile grease or an equivalent. Lubricate ball joint after seal boot is installed but prior to top of seal boot being pushed down below notch in ball joint stud. Air must vent out of the seal boot at notch when grease is pumped into ball joint, failure to do so will balloon and damage seal boot. Do not over grease the ball joint, this will prevent the seal boot from pushing down on the stud of the ball joint.

CAUTION: After the ball joint is properly greased, clip the end of the grease fleeing off below the hex. The ball joint seal boot is non-purgeable and further greasing is not required and can result in damage to the seal boot.
