I’m looking for the torque specs for the lower control arms on the car listed above. The ball joint will be a beast to torque because there’s no room and crows feet love to slip. But any help would be great. Thank you. JD

Hi,

Here are the directions which include torque specs. I am assuming you are referring to the front. If that isn't correct, let me know. Also, this is for the 3.7L.

The attached pic correlates with the directions.

Removal and Installation

NOTICE: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part numbers or equivalent part, if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

NOTICE: The suspension height sensors must be disconnected prior to servicing suspension components. Damage to the suspension height sensors and/or the vehicle dynamic suspension system may occur. The sensors will need to be recalibrated after reassembly.

1. Remove the wheel and tire.

2. If equipped with dynamic suspension, remove and discard the suspension height sensor arm bracket bolt and disconnect the bracket from the lower control arm.

- To install, tighten the new suspension height sensor arm bracket bolt to 30 Nm (22 lb-ft).

3. NOTE: Use the hex-holding feature to prevent the stud from turning while removing the nut.

Using a crowfoot wrench, remove and discard the lower ball joint nut.

- To install, tighten to 210 Nm (155 lb-ft).

4. NOTICE: Use care when releasing the lower arm and knuckle into the resting position or damage to the ball joint seal may occur.

Push the lower arm downward until the ball joint is clear of the wheel knuckle.

5. Remove and discard the lower arm forward bolt.

- To install, tighten the new bolt to 185 Nm (136 lb-ft).

6. Remove and discard the lower arm rearward nuts and bolts.

- To install, tighten the new nuts to 99 Nm (73 lb-ft).

- Install the new lower arm rearward bolts from the bottom of the lower arm bushing with the nuts on top.

7. If necessary, remove the lower arm rearward bushing. For additional information, refer to Lower Arm Bushing See: Control Arm Bushing > Removal and Replacement > Lower Arm Bushing.

Installation

NOTICE: The lower arm forward bolt must be tightened with the weight of the vehicle on the wheels and tires or damage to the bushings may occur.

1. To install, reverse the removal procedure.

2. If equipped with dynamic suspension, calibrate the suspension height sensor. Connect the scan tool and carry out the Ride Height Calibration routine. Follow the scan tool directions.

Let me know if this helps.

Take care,

Perfect. Thanks man. The photo is saying to discard the 8mm bolt that holds the sensor arm to the control arm. Not sure that's correct. At any rate, sounds like new hardware all the way around. Thanks again.
