When your Tie Rod is bad you may have uneven wear on your front tires since the bad tie rod can cause your tires and wheels to be out of alignment.
When you turn your steering wheel to make a turn or hit bumps you may notice a squeaking noise or the steering wheel may feel lose and have a lot of play in it.
Another Symptom that your tie rod is bad is that your steering wheel may shake when you hit bumps.
A bad tie rod does need to be replaced soon since it could cause you to lose steering and control of your vehicle which could end in a deadly crash.
