Oh, just some additional blurb for those that want some more generic maintenance info...
Rear Coil-over-shock units are commonly not user serviceable. They're not meant to be opened as most of them are gas pressurized internally. Their seals don't dry out because they don't have stanchions like air-shock units do (just small diameter piston rods).
The eyelet bushings can be easily replaced though, if they show signs of excessive play. Most shock eyelet bushings these days are the "dry" type, so don't be tempted to grease or put a drop of oil or chain lube in these areas, unless stated in the manual. Lubing a "dry" type eyelet will knurl the bushing material and will wear it out real fast.
