how to repair tyrod

Inner or outer?

inner

Have to take outer off first then take boot off inner tierod then usually need special tool for inner just un screws

The inners are part of the power steering rack. This will require removal of the outer and special tools to uninstall the inner off of the rack although the job can probably be done without the proper tools, but much more of a headache. Personally, I would recommend having the steering rack inspected for damage as driving the vehicle into a ditch may have caused more damage than just the inner tie rod breaking off.
