When ordering parts, refer to the Parts Catalog and enter the VIN of the vehicle being repaired to find the correct parts (and the part numbers) for the vehicle. Alternatively, use the search function in the Parts Catalog to find a specific part for the vehicle.

Repair Procedure

Cut the floor panel at the indicated locations, and bend it back to create a flap large enough to allow removal of the Rear Subframe Mount and to uncover spot welds to be removed when removing the original Rear Subframe Mount from the vehicle.
Cut Line

Reference Line/Point
- A = 20 mm.
Remove the original component..

or Factory Spot Welds

or Drill through factory spot welds
Note
When drilling out spot welds, use a drill bit that creates a hole correctly sized for the fastener that will replace the spot weld.
Prepare for installation.
Note
A red X indicates a location where a factory-installed fastener is not being replaced.

Warning
Failure to follow all welding safety precautions, including the use of personal protective equipment, could result in serious injury or property damage. Only technicians who have completed Tesla’s approved welding training are authorized to weld structural components on Tesla vehicles.

CAUTION
Do not weld on a Tesla vehicle before performing the Vehicle Electrical Isolation Procedure (refer to the vehicle-specific Service Manual for more information on the Vehicle Electrical Isolation Procedure). Welding on a Tesla vehicle with an energized high or low voltage system might damage vehicle components.
Perform GMA welding.
or Steel Plug Welds
Warning
Failure to follow all welding safety precautions, including the use of personal protective equipment, could result in serious injury or property damage. Only technicians who have completed Tesla’s approved welding training are authorized to weld structural components on Tesla vehicles.

Warning
To maintain vehicle crash integrity, use only approved welding wire and an approved GMA welder to perform GMA welding on Tesla vehicles. Refer to Approved Gas Metal Arc (GMA) Welders and Welding Wire for information on approved GMA welders and welding wire.

CAUTION
Do not weld on a Tesla vehicle before performing the Vehicle Electrical Isolation Procedure (refer to the vehicle-specific Service Manual for more information on the Vehicle Electrical Isolation Procedure). Welding on a Tesla vehicle with an energized high or low voltage system might damage vehicle components.

Note
Before GMA welding, a test weld using material of the same gauge and type should be performed to make sure that the welding equipment settings produce a satisfactory joint.
Perform any necessary post-repair operations.
