I have a knocking sound on my front end when I'm braking, steering wheel shakes. What causes this?

First check your lug nuts and make sure they are tight and torques. Then move onto an inspection of the front end steering and suspension. Also take a look at the caliper mounting bolts. Sounds like something is loose and this is safety related so I would not drive it until it's diagnosed. Use this link to find a good shop near you. https://repairpal.com/repair-shops Alex
