What are the warning signs?
They'll click clack for months. In our case, it was a new ball joint, it was just a faulty part so no warning.
If it was a new faulty part, what's the make? One day soon I'll need to replace mine.
It was an OE part. Go with Moog. Lifetime guarantee. If they somehow do fail, you're only out the time it takes to swap...or the labor at a shop
