Steering Gear Replacement Guidelines

Provides guidelines on replacing steering gear after a collision.

For safety, the steering gear must be replaced after a collision or any impact that results in any of the following conditions:

Damage to any of the components listed in “Component Damage (Front)" and "Component Damage (Rear)".
Changes in the operation of the steering gear, as described in “Changes in the Operation of the Steering Gear.”
The vehicle cannot be aligned within specifications using normal adjustment procedures, as described in “Alignment Issues.”

Warning

Always replace a steering gear that has visible external damage.

Note

Use only new, genuine Tesla parts. Do not replace steering gear components with used, recycled, or aftermarket parts or components.

A steering gear without external or visible damage might have internal damage from a collision or other impact that could lead to a steering gear failure. It is not feasible to directly diagnose internal damage to a steering gear, so the conditions listed above should be used to assess whether to replace a steering gear after a collision or other impact.

Contact Tesla Collision Repair with any questions on these guidelines or on a specific repair:

Changes in the Operation of the Steering Gear

Replace the steering gear after a collision or other impact that results in any of the following issues when turning the steering wheel from stop to stop:

Jamming
Catching
An increase in the effort needed to turn the wheel compared to a non-damaged steering gear

Note

Raise the wheels so that they move freely before performing this test.

Alignment Issues

Perform a four wheel alignment. If the wheels cannot be aligned within the specifications listed in the Service Manual (General Information > Technical Data > Wheel alignment) using normal adjustment procedures, replace the steering gear.
