Suspension and Steering
- 2025-09-05: Changed "Breakaway torque" to "Maximum breakaway torque".
- 2025-06-26: Added informational video on lateral and compliance link bushing inspection.
- 2025-06-19: Updated suspension bushing inspection guidelines.

Service Limits
| Item | Limit |
|---|---|
| Noise | The ball joint/ball joint assembly shall exhibit no squeak, grind, rattle, or other abnormal noise when oscillated or rotated. See Noise and Vibration. |
| Dust boot | Visually inspect the dust boot for damage:
|
| Play | No axial or radial free play greater than 1 mm when inspected/loaded by hand. |
| Maximum breakaway torque | 10 Nm |
| Item | Limit | |
|---|---|---|
| Noise | Bushings are designed to exhibit noise in the case of severe degradation. Rubber folds, non-detrimental cracks, and other non-detrimental damage is permitted. Generally, bushings should not be replaced unless there is a noise that exceeds the allowances listed below. | |
| Rubber Deformation |
A bushing that demonstrates a 20% or greater decay in stiffness when compared to a new part should be replaced. On some bushings, the location of the damage can be used to determine whether the part should be replaced. Refer to the images below: TIp More detail on front lateral and compliance link bushing inspections is available in this video. |

| Play | 0 mm. Elastic play is allowed. Any additional play is not allowed. No contact with other component surfaces is allowed. | |
| Item | Limit |
|---|---|
| Noise | See Noise and Vibration. |
| Dust boot | See Ball Joints. |
| Lash | No rotational lash of the inboard joint with respect to the outboard joint is allowed greater than 1.5 degrees (± 0.75 deg) when inspected/loaded by hand (excepting spline connections to the motor/hub/jackshaft/etc.). Levers or other tools are not permitted. |
| Item | Limit |
|---|---|
| Lateral play | 1 mm total, from LH to RH side. |
| Item | Limit |
|---|---|
| Noise | See Noise and Vibration. |
| Play | No angular free play greater than 1 deg (± 0.5 deg) is allowed when inspected/loaded by hand. Levers or other tools are not permitted. |
Corrosion
Replace parts only if corrosion affects vehicle control.
Noise and Vibration
Do not replace suspension components for a noise condition if any of the following conditions are present:
- The noise is less than 11 dB louder than background noise from other sources as observed at the driver’s ear in the normal seated driving position, including all windows/doors/apertures closed and all else representative of a typical driving scenario.
- The noise is not resolved upon replacement with a new part.
- The noise is also present on a suitable reference vehicle (for example, a vehicle in good repair of the same type as the one being examined).
Replacement in Pairs
Suspension components do not need to be replaced in pairs unless stated specifically in a Tesla Service Bulletin.
