 In some of the older cars, when the boot was torn and you had a knuckle issue up in the front, you'd get kind of a grinding or a slipping feel. That's what it feels like. But it's only when it's warmed up and it's only in low speed. It doesn't happen when it's faster. So I ruled out the knuckle, the boot, whatever. But what's going on is it just has that kind of a slip. And they said, oh, it could be the tires. So I replaced the tires and nothing.
