- 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.
-
Remove
the outer portion of the original component.
-
Remove
the inner portion of the original component.
-
Prepare for installation.

Perform resistance spot
welding.
or Installation Spot WeldsWarningFailure 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.CAUTIONDo 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 WeldsWarningFailure 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.WarningTo 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.CAUTIONDo 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.NoteBefore 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.
