Sometimes when I’m stopped or slowing down my truck is like shaking

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Your F-150's shaking and rattling could be a couple of things. Since it happens when you're stopping or slowing down, one likely suspect is the brakes—worn brake pads or a warped rotor can cause vibrations and noise. But if it feels more like the whole truck is shuddering, you might be looking at an engine or transmission mount that's seen better days. These mounts cushion the engine and transmission, and when they wear out, they let things rattle around more than they should. Another possibility? A loose heat shield or exhaust component. Give the underside a quick inspection if you can, and if it’s still got you scratching your head, a mechanic can pinpoint the cause pretty quickly.
