1998 Volvo S70 Axle assembly and Sway bar link

Tires and Wheels problem
1998 Volvo S70 Front Wheel Drive Automatic 182000 miles

I recently had my front and back axle assembly replaced, my left front sway bar link and a spring seat front strut mount within 4 months of each other. After this particular work was performed, should a front end alignment be done to make sure the tires are rolling correctly?
Within a few months of this work, I noticed my front tires were starting to wear excessively on the outside tread of the tires. I then started noticing a "shimey" in the steering wheel.
Well come to find out, the Assurance comfort tread front tires which I purchased in 3/2008, with less then 13k mileage on them had a tread measure of 4 out of 10 and the back still had 9.
I believe the repair shop who did all the work on my axles, etc. Did not give me a front end alignment and caused my tires to incorrectly wear. According to a major tire manufacturer, they say an alignment is necessary when replacing these parts.
Please let me know your opinion. Thanks.
