I think that it is the shock, or possibly the strut mount, but when I hit a bump, the driver side rear makes a squeaking noise. Is this the strut mount bushing, or the shock that needs to be replaced? And, if that's not enough info, than how do I check to see if it's one or the other, or something else. I'm 99% sure it's coming from the suspension.

 

Try to lay under the car or on the edge of it and have someone compress the suspension and see if you hear it.

 

If you can't figure it out, then maybe:
One at a time, try to lube bushings and suspension joints, and see if one of them changes the noise. Maybe Tech could tell you what type of lube you could use? Spray silicone? WD-40? Brake Fl?

Silicone or WD works good.
