So... it would seem that my right rear shock is knocking around :s

Is this normal wear and tear? And will I need to replace all 4 shocks? Is this a simple process that I could do myself? Help!

 

replacing shocks is easy - if it's knocking around that could be simply loose tophats (bad) or loose anything else (very bad). so be careful driving if you're unsure...

as for replacement - best to do all 4 if you think this is sign of how the car was driven before you; at the least, replace the pair in the rear w/oem or equivalent while you sort out what type of suspension you're looking for to supplement your driving style
