I went out in the rain last night for a quick play. The diff was failing to lock as it normally would. I did a drift day at Oulton park about 2 months ago and this was the first time I have driven it in anger since I have a s13 with a standard viscous LSD.
The cars done 95k and I would imagine the diff oil has never been changed. Do you think an oil change would solve the problem? How else can I restore it so it will lock up properly again?
And before you mention it, I'm not interested in welding it :-)
Thanks for your advice in advance.
