What to check for on front end or engine?

What is your question?

Driving with cruise set at 45mph. Doors started locking and unlocking on own. Shut down my instrument panel( electronic). Service brake system read on display. Lost power steering, could not get truck to move past a crawl. I shut off truck and waited. Check engine light still on, was able to drive normal again when I hit a bump and front driver tire made tapping sound. Any ideas? First time it has done this. Front driver tire has been making some tapping/popping noises for about a month.
