FEBI42154 Febi Ball Joint

Basically, this lets your wheel turn and move up and down. It’s a spherical bearing, so it allows for a lot of movement while still keeping everything securely connected. Think of it like your shoulder joint – it’s what gives you a range of motion, but it needs to be strong. The castle nut and cotter pin are how we lock everything tight. The castle nut has slots cut into it, and the cotter pin goes through those slots and a hole in the stud, preventing the nut from loosening. It connects your control arm – that’s the part that holds your wheel assembly – to the steering knuckle, which is what actually steers the wheel. It’s a crucial point where a lot of forces come together – from bumps in the road, steering inputs, and even just the weight of the vehicle. It’s part of what allows the suspension to do its job. If this wears out, you’ll notice a few things. Usually, you’ll get clunking noises, especially when going over bumps. Sometimes it’ll feel loose in the steering. It can cause uneven tire wear, too. If it fails completely, it’s a serious safety issue – you could lose control of the vehicle. It’s a wear item, it will eventually need replacing. We’ve got a pretty good selection of these at Fixparts Online if you're looking. It’s one of those parts you don’t want to skip on, good quality is important here.
