2000 Pontiac Bonneville I hit a pot hole

I hit a sink hole or extra large pot hole. I had to replace the rim and tire they were destroyed. My cars dash lights inside went crazy. Stability system, oil gauge stuck, check gas cap and service engine soon lights came on. Also the speedometer jumped to kilometers. Than my car when I would go above 50 mph would shake. I took it to a body shop where they found numerous suspension things wrong outer tie rod, hubs and bearings. But said that this could not of happened from hitting a pot hole.
Why would my car have all these problems happen right after I hit the pot hole.
