Ford Mustang Alignment 2015-Current

The sixth-generation Ford Mustang is the first to have independent rear suspension. In addition, the front suspension was a complete redesign from earlier versions. Aligning this Mustang is not that different from some of Ford’s other products, but you do have additional steps that involve the electric power steering and inspecting the camera and radar systems.

Front Suspension

2015 Ford Mustang Front Suspension

The front suspension uses a MacPherson strut and two lower control links. The camber is adjustable by installing cam bolts in the upper strut bolt hole. This should allow for plus or minus 1.75 degrees of camber adjustment.

Caster is not adjustable. If you see the caster is out of alignment, it could be a sign of damage to the subframe or control arms.

Rear Suspension

2015 Ford Mustang Rear Suspension

As the first generation of Mustangs with an independent rear suspension, the design is complex with four elements attaching the rear knuckle to the body and other links. 

The goal of Mustang’s engineers was to improve handling and traction, so owners do not lose control while leaving a car show. The suspension includes what Ford calls an integral link that attaches to the lower trailing arm and the knuckle. The link is designed to hold the knuckle upright when power is applied to the rear wheels, preventing unpredictable and dangerous wheel hop.

The toe is adjustable with a link under the lower trailing arm. The eccentric is on the outboard side of the link. Make sure the toe and thrust angle are very close to the specifications because ignoring them now can make the post-alignment calibration procedures much more difficult.  

Camber is adjusted using a factory-installed eccentric on the upper control link. If the customer has lowered his or her Mustang, there are aftermarket adjustable links that can correct up to three degrees of negative camber and two degrees of positive camber.

Steering

The Mustang uses electric power steering. The system uses an electric motor coupled to the steering rack by a toothed belt. The steering angle is computed with position sensors on the motor, angle sensor on the column, and data from the ABS module. 

Mustang Electric Power Steering

The PSCM uses a temperature sensor to monitor the internal temperature of the EPAS gear –this DTC appearing by itself does not indicate a fault condition in the steering system. If the system detects higher than normal temperatures, codes will be set in the EPAS module and ABS module in some cases.

Diagnose all other EPAS DTCs before aligning the vehicle. Overheating can be caused by a missing heatshield, heavy loads (low-speed maneuvers) or high ambient temperatures.

An example of a heavy load would be multiple parking lot maneuvers over a short duration of time with low tire pressure or towing for long distances, followed by multiple parking maneuvers.

When performing a toe adjustment in the front, check the data for the steering angle sensor. It should be at zero degrees. If not, a calibration procedure needs to be performed. 

ADAS Features

The 2015 Ford Mustang is equipped with automatic braking and adaptive cruise control. The system uses a camera and radar mounted behind the grill. If the messages “Front Sensor Not Aligned” or “Adaptive Cruise Not Available” are displayed in the instrument cluster, you need to perform the calibration procedure. 

First, inspect the radar sensor at the front of the Mustang, behind the bumper cover on the left side. Inspect around the bumper cover for evidence of a collision. If the sensor is not damaged, clear the codes. The calibration process requires just a test drive in a target-rich environment. Once the system has detected 250 targets it will turn off the warning message in the instrument cluster. This procedure must be performed in one key cycle. If the messages do not turn off during the test drive, check for codes.
