99 Civic Front end squeak

I have a 1999 Civic that,starting today,is making a pronounced squeaking noise in the left front of the vehicle whenever I go over a bump,and also when I stand outside the vehicle and push down on it.About 35,000 miles ago I put 4 new struts on it,and I am taking it back to the mechanics (chain store) to have the rear struts replaced because they have gone bad.My question is,could the left front squeaking also be a strut?Or might it be the ball joints or a bushing problem?How would I go about testing these parts?Because I am taking the car in tomorrow,I would like to try to get an idea today before they see it.Thank you so much for your time and help with this!

1999 Civic's dont have struts (Honda didn't start putting a strut suspension on Civic's until 2001). It might be a squeaking shock absorber or spring, so check the condition of those.

Also, if you press down on a corner of the car, the car should only bounce back up once (very slightly too) so if it's really bouncy then i'd say it's a spring issue.
