Steering gear — removal and installation Ford F150

Warning: The models covered by this manual are equipped with a Supplemental Restraint System (SRS), more commonly known as airbags. Always disable the airbag system before working in the vicinity of any airbag system component to avoid the possibility of accidental deployment of the airbag, which could cause personal injury.

Caution: Before replacing the steering gear, the original unit must have its data uploaded onto a scanner and saved before it is removed from the vehicle, then it can be downloaded into the replacement power steering control module. Caution: Always make sure the negative battery cable is disconnected before disconnecting any of the steering gear components. Failure to do so can result in damage to the EPAS (Electronic Power Assist Steering) system.

1. Disconnect the cable from the negative terminal of the battery (see Engine electrical systems).
