It's okay for the sway bar to slide a little side to side, especially the 05 - 07s which have the "bayonet style" lower end links. As long as there is no metal-to-metal contact when doing so, it should be fine.
Check the track bar ends (upper and lower), the steering stabilizer, lower shock mounts, ball joints, and front axle U-joints. Jack the truck up and put the front end on jack stands so you can check each component individually with the suspension unloaded.
WARNING: Be sure to use appropriately-rated jack stands, and to set the parking brake and chock the rear tires. This aint no Prius. These trucks are very heavy - especially in the front!
