Tesla Model 3 Strut Assembly Replacement Guide

Quick answer

Replace your Tesla Model 3 AWD front strut assembly by using a pre-assembled unit. This saves time and reduces complexity compared to swapping individual components.

Step-by-step strut assembly replacement

1. Prepare the vehicle: Park on level ground, engage park brake, and loosen the front wheel lug nuts while the car is on the ground. Jack up the front and place on jack stands. Remove the wheels. Never work under a car supported only by a jack.
2. Disconnect the upper strut mount: Locate the three nuts securing the top of the strut assembly to the vehicle frame (under the hood). Use a socket and breaker bar to remove them. Do not remove the center nut yet. Support the strut assembly from below before removing the last nut to prevent it from dropping.
3. Disconnect the lower strut mount: Remove the two bolts that attach the strut fork to the lower control arm. You may need to use a pry bar to separate the fork from the control arm if it's stuck. If the bolts are stubborn, apply penetrating oil and wait 10 minutes before trying again.
4. Remove the old strut assembly: With all bolts removed, carefully pull the old strut assembly out from the bottom. Watch the brake line and sensor wiring to avoid snagging. Inspect the old strut for leaks or damage—this confirms replacement was needed.
5. Install the new complete strut assembly: Position the new FCS Auto strut assembly into the lower mount first, then guide the top into place. Hand-tighten the lower bolts, then the upper nuts. Torque to manufacturer specifications (upper nuts: 18 ft-lb, lower bolts: 81 ft-lb for Model 3 AWD). Use a torque wrench—overtightening can damage the strut mount or control arm threads.
6. Reinstall the wheel and lower the car: Put the wheel back on, hand-tighten lug nuts, lower the car to the ground, then torque lug nuts to spec (129 ft-lb for Model 3). Repeat on the other side. After lowering, bounce the front of the car a few times to settle suspension before final torque.
7. Check alignment: Replace both struts, then schedule a professional alignment. The suspension geometry shifts slightly after strut replacement, and an alignment ensures even tire wear and straight tracking. Driving without alignment can cause premature tire wear and poor handling.
