Mine wore out internally.

Test the steering gear with the engine off hold one at a time the tie rod and have a helper steer left and right. If there's play on the rack it's obvious it'll click as it lifts off and reconnects.

Many many ball joints and bearings up front an uncommon but definitely happens fault is the bearing at the top of the strut will "feel" like it's in the stewing gear.
