Below are the axle nuts used on both axles. They are both 36 mm nuts however I
believe the nut used on the Q45 is of higher strenght/quality than the 300ZX nut.
It also appears to be zinc coated due to its yellow/gold coloring. Below you'll
see why I believe the Q45 nut is stronger.

The Q45 was considerably more rusted out than the 300ZX likely due to coming from
a salt state (Illinois). However, hammering the Q45 axle out of the hub was much
easier than the 300ZX. In the process I found that the nut didn't handle the blows
well at all, which makes me think its made of a lesser quality steel than the Q45 nut.










Also in those pictures you can tell that the threading is slightly bent... I was
getting pretty bent myself trying to get the damn axle out so started taking my anger
out on it... it worked! It finally came out and since I don't need those axles no harm
done... :D Also worthy of mentioning is the strength of the wheel studs. Since the stock
differential had already been taken out of it, it has no engine, and no tranny I had
only one immediately available option of breaking the nut loose... use a pry bar between
the studs. I put the lug nuts bad on to protect the thread and put a steel bar between
them. The pictures will explain what happened...






Apparently that metal wasn't tempered very well or whatever but anyways I just used a
higher quality pry bar and that did the trick. More to come soon!
