How to change a turn signal light on a 2001 saab 9-5?

[steve g]

I was just curious if anyone knew how to change the passenger side front turn signal light on a 2001 saab 9-5 areo? Also, the other day I was driving down the highway at around 70mph when I hit a massive pot hole (couldn't see it cause of darness). Now the car pulls to the right, I'm hoping it only needs an alligment, but how can I check for other things before taking it in to get fixed tomorrow? It pulls moderetly to the right, and also makes sudden jerks to the right? any help on both these questions would be great!
