  Q: How to remove the lower control arm on Chrysler 300M?

  A:

  The first thing to do is raise the vehicle onto jackstands or a frame contact hoist, then remove the wheel and tire assembly. Following this, you should pull out the ball joint stud after removing the nut and bolt from the Steering Knuckle. Don't rush, since pulling away from the steering knuckle while the ball joint release may lead to the separation of the C/V joint on the inside. Don't let the ball joint seal come into contact with the steering knuckle; if the seal tears, it should be replaced prior to putting everything back together. Gently pull the ball joint stud away from the steering knuckle by pushing down on the pry bar. Disconnect the tension strut to cradle attaching nut and washer from the end of the strut. As you do this, hold the entire strut down with an open-end wrench to make sure it doesn't rotate. Change the retaining nut to a new one when you install the cylinder head. Take out the lower control arm pivot bushing from where it is mounted in the cradle, then pull the tension strut through the bottom isolator bush to remove the assembly from the lower control arm. After that, take out the tension strut to control arm retaining nut and washer from the strut end. Hold it in place with a wrench, throw out the retaining nut, use a new one when reinstalling and separate the tension strut from the lower control arm.

  Q: How to install the lower control arm on Chrysler 300M?

  A:

  Before installing the lower control arm, align the tension strut in the lower arm so that you can read the stamped word Front from the arm, not the strut. Fasten the washer and new retaining nut to the tension strut on the control arm while using an open end wrench to hold the flat of the tension strut still as you tighten the nut to a value of 130 Nm (95 ft. lbs.). Proceed by mounting the tension strut and isolator bushing end and the lower control arm pivot bushing end into the engine/suspension cradle and cradle bracket. Install the lower control arm onto the cradle bracket by pushing on the pivot bolt. When you install the washer, grab the tension strut, fit the new strut to cradle the bracket nut and tighten it to 130 Nm (95 ft. lbs.) while you hold the tension strut in the flat with an open end wrench. Be careful not to withdraw the Steering Knuckle after taking it out of the ball joint, since you might rupture the inner C/V joint. Installing the ball joint stud in the steering knuckle should not cause the ball joint seal to touch the knuckle, so avoid this and change the seal if the seal gets ripped. Fit the lower ball joint stud into the steering knuckle and hold it there using the clamp bolt and nut, tightening the clamp bolt to a torque of 55 Nm (40 ft. lbs.). After this, put in the wheel and tire, join the hub by tightening the stud nuts in the correct order to half their maximum torque and then do it the same way to bring the full torque up to 129 Nm (95 ft. lbs.). The final step is to settle the automobile so its own weight rests on the suspension and clamp the lower control arm pivot bushing tightly, achieving 142 Nm or 105 ft. lbs. at the motor to the gearbox mounting bolts.
