Yeah right oil dont worry I'm not a newby to mechanical stuff. I know just about every bolt in the GQ now haha. Almost all have been undone and redone atleast once lol.
Anyways it wasnt just the binding up. That was only in low range 4x4 while at full lock. So I guessing the metal in oil was making it sound like that. I dropped the oil and its very metallic so my guess is one of the bearings has let go. The whine also indicates this and oil is now seeping from front pinion. But not overly stressed I swapping diffs over soon as I get me drop boxes anyways.
I put it to the missus last night if she wants to come or just wants to spend the weekend with her parents in wodonga so that has her thinking. Might be easier on us both as not sure how the lil one will go when we disappear for hours doing tracks etc. I dont wanna be holding everyone up when she needs changing or cracks the sads lol.
We'll see how we go.
