Chrysler Pacifica 2006: Front End Work

On February 16, 2015 I had front in work to fix the knocking noise I was
hearing in the front of the car every time the car drove over badly paved
roads (no noises on good roads). Something was loose and just bouncing
around even on good roads, if I went into a small divot in the road I would
hear it (very annoying) .  I took it in (144,666 miles) and had the following
fixed:
2-inner tie rod ends
2-outer tie rod ends
1-passenger rear wheel bearing
2-sway bar links
1-front end alignment
plus 5.5hrs labor
Total cost of all this is $1080.59

NOW I have the same knocking issue in October 2015 at 151,696 miles (or
7k miles of driving). Question is should I have the same problem after only
7k miles of driving.  I want to go back and have the shop fix this.
