Using the hub nut spanner means you can't measure the torque. A common method used to great effect is do the inner hub nut up tight, rotating the hub as you go to seat the bearing. Once tight back off "1 flat" fit lock tab washer then the outer hub nut, do that up firmly, feel for play, hopefully there won't be any noticeable movement - bend lock tab washer - job done. Give your brake pedal a couple of presses just to make sure the caliper pistons have not been pushed too far back and that the pedal feels right before driving. Re-fit drive flange/halfshaft, seal with new gasket or RTV silicone, apply threadlock to drive flange bolts and torque up to correct setting then put the wheel back on.
Do make sure that your bearings etc are clean before you put them in and that they are appropriately packed with grease, premature failure is not unknown because the bearings have been put in dry.
However, it is always worth checking the bearings for play every once and adjusting as necessary, especially if you are running wider than standard wheels/tyres or if you have been doing a lot of wading.
If you want to torque the bearings as per spec you're gonna need a BIG socket to fit yer torque wrench.
Hope that helps ya.
