Got some good news vs some bad news.
For those that know about the saga of my diff problems recently. Long story short. Bought the diff from Simon. Worked fine for a while, went to Kadina for the show etc and busted the diff while under normal operations. Pulled the diff out to sus out the actual problem. One of the half shafts was completely stripped, 5-10mm from the end. Took the diff to AM Performance. He sorted the diff out for me. Got it back to being working again with another half shaft, pulled the diff out of the housing to give it a clean and remove all metakl shavings.
After nutting it out for a while, we realised that the old diff, which was a Active LSD (very similar to the GTR) is a lot wider then the current diff housing (350mm vs 310mm) What seems to have happened is that it all fitted fine, but as the car was being driven under load the half shaft seems to have been pulled out and hence putting stress on the end of the half shaft which caused it to strip. So now I am just wondering if someone can give me the length of the 2 different half shafts. GTR and normal GTST. Is there any difference? These are the half shafts that go from the diff to the wheel/hub.
Any help is greatly appreciated
