Specifically, how do you know when they are going out. I occasionally THINK I hear a pop when turning or stopping; one of those things that I can't be sure if I really heard it, or my brain said it heard it, and the mufflers on my SLP system occasionally bump the underside of the car, so I'm not 100% sure what (if anything) I'm hearing, or if I'm just being paranoid.
When driving a highway speeds, the wheel is rock solid, no play at all.
So my question...should I be concerned? When Tie-Rods start to go, doesn't the wheel also start to feel loose, or have a shake to it?
I'm at 146,000 miles, and have a 70 mile a day round trip commute on the highway, and the last thing I need is a front wheel falling off while I'm doing 70 in rush hour traffic (honestly, that would probably actually BE the last thing that would ever happen to me).
