This Diff (and case) have come out of my CSR (just over 10,000 miles). I had the diff oil changed when I bought the car (Sep 2020). It has worked perfectly for me with no noise or slop. It has only been changed it as part of a larger bout of upgradeitis (new tracsport LSD, new 5 speed gearbox, new dry-sump, various other bits and bobs at Premier Power). Price is £800.00 + PP if wanted If you're interested it could be collected from me in Cardiff or failing that I'm sure we could arrange postage (I'm unsure what it would cost but could find out). Thanks for looking, Ed
