Lower control bolt that mounted to subframe rusted threw frame . If not caught on time the tire would seperate I took the vechicle to a wedler for temperary repair. But unfortanley the design on the subframe has holes so it allows water to enter and cause frame to rust! alert when braking you may experience clunking that is the lower control arm bolt broken. Very dangerous. I have vechicle with physical proof of rusted frame if needed I can take pictures when the time comes.
