Alignment after stut and upper control fix
 

Just replaced Front Struts and Upper control Arms on 2004 Sebring. Do I need to get an alignment?

In a word...YES, unless you want to continually check tires for signs of abnormal wear for the next few thousand miles.

Just wandering because the strut and upper control arm are just unbolt and bolt in new stuff. not messing around with any adjustable parts for Caster Camber. Anyways car is not as noisy as it was up front.

What I mean is no noise at all in front end, but car is noisy because put on studded winter tires.

Lack of alignment doesn't cause noises, it causes abnormal tire wear. You can't diagnose misalignment by listening to the car. The front end can get out of alignment from general wear and tear, hitting potholes in the road, etc. If it was out of alignment before your work it won't be any better now. The only way to know that it is or is not aligned properly is to have it checked on an alignment machine. Monitoring tire wear carefully is important, but by the time it shows up as a wear pattern on the tires, you've chewed through a lot of rubber unnecessarily.
