Tie rod threads completely machined + creaking lower control arm

[afristang]

Hi everyone,

I was inspecting the front passenger side of my car for a noise when turning right. After feeling for the creaking, squealing, and noise, I concluded that it is a problem with the lower control arm or a bolt in there that is not tightened properly. I have no tools on me right now but I will try to fix it tomorrow.

However, while searching for that, I found out that the tie rod threads on the car has been completely machined on top. For info, the roads where I live aren't always great.

Please ignore the rust, I live by the beach in an extremely humid area. Here is a picture of the tie rod.

My questions are:

First, is it safe to drive with a creak in the lower control arm? It only does it when the car is warm and at low-ish speeds.

Secondly, is it normal that the threads of the tie rod are machined like that? My steering is dead straight and I have no issues turning the car. It really feels like new when steering.

Thanks.
