Looks like leaking fluid near the universal joint . Wet from rear u-joint to bottom of diff. How difficult to replace front seal in diff? I have tools, jack stands and basic mechanical skills can I do this myself?
Upon start up after the cars sits overnite or especially when it sits for a few days, I will see blue smoke come from out of the exhaust pipes. This car has less than 19,000 miles, was bought brand new and never driven by anyone except me and my wife. Oil changed every 5000 miles with Mobil 1 5W20 and the car has never been abused. Car is still under warranty, it does not look normal to me, why do you think?
How hard would this be for me to do it myself. I have ramps, jackstands and am mechanically inclined. I do all my own brake jobs, change hoses, belts, oil and filter changes. I have worked on motorcycles for over 45 years.
