Confirm tire pressure. Any odd tire wear patterns? Crawl under to check (visual, shake) the sway bar links/bushings, and the steering linkages. Anything cracked, torn or missing? How are the shocks? Give it a good bounce. Raise the vehicle and check the hub & ball joints by holding the tire at 9 & 3 and shaking to see if there is any play. Repeat at 6 & 12. Any odd noises (scrapes, rumbles, squeaks)?
