Why not get under there and check them first? You'll get no improvement from replacing good parts.

nglitz is right on target here. Diagnose BEFORE you replace parts. It is very easy to diagnose these items using the four P's; push, pull, pry and prod. If something is loose, figure out what and replace it.

Replacing parts on a trial and error basis is an expensive and frustrating road to follow. You can go to a tech and have it diagnosed and save money because of the lack of unnecessarily replaced parts.

Good luck,
