2004 Hyundai Tiburon hub assembly replacement question

The wheel seems to be in good condition, although not perfect, the good part is that the winding noise has stopped, but even after I put the new hub assembly on the entire wheel has about a quarter inch or more of play in it, and I was wondering if maybe I could put another (spacer washer) on the nuckle to stop it from haveing the play in it.

I was also wondering if its better to use a neumatic gun for tightening the hub nut instead of wrenching it on there by hand, because this particular model does not come with a cotter pin

I torqued it at about 80
but thank you I didnt think about the bushing,
do you think by adding an extra spacer washer in the hub before the nut gets on, that it might be a tighter fit?
Once again I really appreciate your time

Great I i'll go for it
my newest addition for the retry
is I went ahead and got ahold of another nut that is the same thread and slightly larger in girth, im going to make a new attempt on this tomorrow and hopefully it should be okay but I cant thank you enough for your help. This is a great website you operate.

I have to tell you im very impressed with your website its very instructional, I currently work in a small repair shop and usually do the basics for auto and diesel repair, but my main question was I was considering going back to school to possibly get a master certification out of the business, do you have a recommendations as to what schools would be good to attend?

That sounds great, I believe your right, because im one of those older guys who actually got a job in the field doing the work and learning the trade years ago as aposed to schooling, and I felt the experience was a lot more valuable than what i've heard about in the schooling aspect. But I would like to learn about hybrid technology more and be able to condition my self for todays job market and im also trying to get out of california and find a job elswhere, if you have a recommendations, that would be wonderfull.
