If all of them quit working at once, it's either a fluke or your main switch in the driver's door trim has gone bad.

Several things could cause it, from bad wheel bearings to worn ball joints...Get your alignment checked. While they're doing it, a good shop will tell you if anything needs replacing to keep alignment true. Be sure and tell them about the brakes causing a shudder.

usually along the frame rail or within the frame rail. get a flashlight and follow the fuel line from the tank, hope it's not in the frame rail, i really hate changing those, hope you have small hands, lol
