Hi i'm new to these forums so forgive me if i sound a bit newish.
my RR sport which i have had from new 2014 been regularly serviced by main dealer and one specialist is leaking from the rear diff. i'm told that its a common problem due to the rear diff pinion seal. i've also been told that JLR have repaired under goodwill gesture as these are isolated to the 2014 model and mine has only done 21000 miles. L R main dealer has quoted me app £1200.00 to change it "ouch" is there anybody out there that's had the same experience and what's been your success in getting JLR customer service to put it right out of warranty
