If you want to perform repairs to your CCM R45 then it is usually recommended to have access to a Workshop Manual to keep just for personal reference in case that you want to know proven methods to take out a certain part for example the Wheel Bearing and match it again effectively.
CCM R45 Workshop Manuals will provide you with targeted diagnostic information for your car so if something is playing up it can help you identify what the issue is and how to resolve it. You will be able to determine if this can be achieved by yourself or that the job is simply too big you can actually make a reservation for your R45 into a decent car garage.
