After almost being killed several times while riding my motorcycle, due to inconsiderate southern ca. drivers I've hung up my helmet and bought a car . I've always loved the 2005 300c. so I got one. I knew at the time of purchase that the rear differential needed to be replaced and the owner had in fact purchased a replacement at the local scrap yard. so now I've got the car on jack stands in my garage and I was hoping someone here could help me with the information needed to replace the differential. is there a free downloadable shop manual anywhere that isn't a scam where I have to download there crappy extension only to find out they don't even have the manual I need. I'm pretty handy with tools and was told this wasn't to difficult a job for me to take on, I just need a little guidance.. Thank you in advance for your assistance in this matter, and for allowing me to join your group.
