98 Grand Voyager front LCA bushing replacement

I have a Grand Voyager that was hit (t-boned) on the L/S a couple years ago. We took the car to the dealership (my mistake) for the repair. Apparently, they did not install the LCA bushing correctly as it is now shot (the R/S is fine with 80,000 miles on it).

Now, I am skilled at older cars and right now am restoring a 66 Mustang, so I do have some clue. But when it comes to these newer plastic cars with metric bolts, I am somewhat lost. How difficult it the replacement of this bushing, Do I really need the "special" tools or is there some backyard tricks and do I need an alignment after??
