Since you're new, as a rule of thumb, before I do any mid-level or higher repair to my Mounty I check the forums here. It always gives you a heads up of what to expect and tips and tricks that the smart guys on these forums know. That being said, you will usually also see warnings about aftermarket brand parts if they shouldn't be used.
A great example is the blend door actuator that controls the heating temperature...I read those threads and every single person on there said Dorman typically makes good products but to stay away from their actuator and buy the factory part. I didn't waste my time, enough people before me wasted theirs.
So if you want to replace some tie rod ends, search some of the tie rod end replacement threads on here using the search tool and see what they have to say. After you read those, if you still have a question, then ask. Usually you won't get many replies if you ask a question that's been covered a hundred times because people expect you to search and figure it out.
Tie rod ends, I would say you are fine using whatever reputable aftermarket brand that your local parts store has. Happy hunting.
