Coarse vs. Fine Wheel Studs
Pretty sure I've got a wheel bearing going. Looked up autozone for hub assembly. Can somebody please explain why there is a difference between coarse and fine thread studs? Basically it amounts to $100+ Not sure what I have because I haven't looked, but would I be able to reuse my old studs and buy the cheaper coarse threaded hub assembly if I have the more expensive fine threads?

by no means am I saying that you can't, but your studs shoud be pressed into place on the hub. So removing the original and putting them into the new part is a no in my opinion. Not saying that you can't buy new fine studs and replace the coarse ones though....
But me personally, I would just buy the correct wheel bearing and be done w/ it.

I don't have a problem buying the correct assembly, but my concern is why is there a $100+ difference between coarse and fine threaded studs? Doesn't make sense too me and why is there even a difference at all?

Your '04 has fine studs, they are 14mmx1.5, earlier studs (pre '02 I believe) are course and are 14mmx2.0.
Look at Rockauto.com, they have the part you need for around the same price as the cheaper one listed at Autozone. Definitely go with Timken brand.

from an engineering standpoint, fine threads tend to be stronger than coarse threads.
that said, it really depends on the thread specs, and method of thread forming.
i would imagine that the $100 difference has more to do with the internals of the wheel bearings rather than the threads on the studs

Thanks for the help. I'm definitely a Timken guy, just replaced one on my wife's trailblazer and the lady at Autozone told me her husband forbids her from bringing home Duralast even with her discount, lol. Off to bed but I will definitely check out Rock Auto. How do you order from them through here or is there a discount code?
