Well what I done was just thread in the new tierod and use blue loctite on the new inner rod threads. Since the thread chaser was an odd size. Then wrench the crap out of it until its tight. It never came off and its been like that for a year. Of course it will mangle up the new inner tie rod threads as you tighten it making removal a impossible job or a really PITA to remove. Then I would cake the treads where the inner screws into the outter tierod and its nut for the alignment adjustment with anti seize so you do not need to replace the inner ones again.

If you want to replace this rack and pinion I would just get a new power steering hose for $20 and and return line for a few bucks while your at it. Since they torque the fittings on the steering gear very tight. IT will require lowering the subframe to get room to remove it. At least the steering shaft is easy to unbolt from steering wheel with no dust boots in the way. Just do not turn the steering wheel once you disconnect it or you will be replacing a clock spring for the horn and airbag system.
