Is that nut on far enough? It looks like it's hanging on the last thread. I had my Hammerhead block milled on the right side like he guy above. Compare the thickness to the stock block.

Hey Mike, It does look bad in that pic but there is 2 full threads exposed passed the end of the self locking axle nut..It's all sweet.
