Replacing C230 Kompressor 1999 Engine Mounts
 

My 1999 C230 Kompressor vibrates on idle. I have taken a flashlight to the engine mounts and they appear to be leaking oil. I am convinced that both the left and right require replacement. I went to an independant MB mechanic who wants $320 for the job, both parts and labor. Years ago I replaced the engine mount on my Volvo 1800ES myself with not much difficulty. I searched around and found that the mounts can be purchased for less than $150. Does anyone have experience doing the replacement? Are their any diagrams available which specify exactly what to remove and it what order? I don't know that I want to do the job myself, I'd like to have a little more information before I make a decision.
