@theresajan50992 we most certainly all understand your concerns. Your tie rod ends are installed properly. No, nothing is going to fall off immediately. Bad alignment may cause your tires to wear odd, and your Durango may pull more to one side. Again, not a big immediate issue,
Should I get a second opinion? Would it be safe to drive it another shop? The way I look at it, your trust in this shop is gone. No matter what they do or say, you will always have doubt about it. Yes, I suggest you get a second opinion somewhere else. It's more a state of mind but that is sometimes more important than anything else.
