Shocks is an easy DIY project, not too complicated or difficult. Simple matter of one, possibly two bolts/nuts holding the lower end of the shock to the control arm or rear axle. Plus one (usually doubled) nut at the top. There is a fancy little tool for holding the top shock rod while loosening the top nut(s), but I've never used one. Found that a 1/4 inch open end fits just fine for holding the rod.
You will need to lift the car to access the lower nuts/bolts. A set of ramps will work just fine, or place the vehicle securely on appropriate jack stands. Under NO circumstances should you work under a car supported solely by a floor jack.
I would also like to suggest checking out the prices of replacement Bilstiens right here at the PartsShop.
