I have a 2000 zr2 4x4. Been noticing latley a toe in/out issue...(more road noise & above normal wear outside edges of front tires, l & r). Now when I brake on right turn get a vibration, noise & pedal movement, (pedal drops). Any thoughts what's causing this?

 

Bad hub, ball joints maybe. Jack up the front grab the wheel at 12 and 6 then 9 and 3 and wiggle it to check for looseness
