My 2005 is coming up on the 50,000mi marker. I was compiling a list of services required and was wondering if I missed anything. What I'm doing is: oil/filter change, trans. flush/filter change, spark plugs?, coolant flush?, set of pads all around, and shocks because of failed bounce test and rougher ride. Now do I have to change and of the diff. fluids or tranfer case? Any insight would be helpful. Thanks in advance.
