I'm not sure why you'd use the term "interference fit" here, but no. It's a tapered stud.It's amazing you didn't wreck with that happening. From the pics it doesn't look that bad. Personally I'd take the wheel off & inspect the hole on the knuckle which is an interference fit with the tie rod end. If it's beat up then you need a new knuckle which is expensive & might have a long lead time. The tie rod appears to have good fit surface & threads, just some slight damage on the top & very well might be fine. If all was good I'd just torque a new $2 nut (6505623AA) on it & say good bye to the dealer. I doubt that ever had a nut on it to start with because the interference fit locks it in place plus the nut is also a locking type. The dealer & jeep are probably scared to death of the liability issues, that's a very dangerous thing to forget.
