how do i detach the knucle on the front wheel from the HUB? there are no bolts.
Press the hub out of the bearing, then press the bearing out of the knuckle. There will be a snap ring holding the bearing in place.
What kind of car?
It will probably need press work at a machine shop, after you get the steering knuckle detached from the car.
Before your question can be answered, we will need to know the year, make and model of the vehicle you are working on…
