Driveway Pinpoint Test
Find a safe, empty parking lot. Drive in a slow, full-lock tight circle (like you're doing a U-turn at minimum speed) and accelerate gently. If you hear a rhythmic click-click-click or pop-pop-pop that gets faster as you go faster, that is a classic worn outer CV joint. Then inspect the CV axle boots (black rubber accordion bellows near each front wheel hub) — if you see grease splattered on the inside of the wheel well or the boot is split, that joint has been running dry and is damaged.

A CV joint that runs dry and is not replaced will eventually snap. A broken CV axle at highway speed causes immediate loss of drive to that wheel and the broken shaft can damage the transmission housing or jam against the wheel — a $400 repair becomes a $900–$1,500 repair with possible tow.
