Well I did the right thing and went out with clunk to try out his newly purchased gq, I Had been greeting a bit of a bang in the hubs occasionally when in 4wd and turning, well today it let go a bang and then there was a whirling sound it think it's something to do with the locking hubs. My hope is it's something simple like the hub spline and not the axle spline. I'm share there will be plenty of others with a story to tell.
