Rear hub bolt torque r34

[drifter17a]

I downloaded the gtr r32 manual which I understand will be pretty much same as r34

 

i rear the page in screenshot and if I understand correctly, the torque for the 4 bolts are 78-98 nm. Why a range? 
 

what does number below it mean( 8-10 ,52-78)?

You cut that screenshot a little short; immediately below it 

First number is torque in Nm, then in brackets kg-m followed by ft-lb

I'm not sure why they provide a range, I have always aimed for about 80% of the top to leave a little room for error

Silly me, thanks mate:)

The ones in brackets are the first stages of tightening.

I usually aim for the middle of the range. They give a range because it's actually not that critical to hit exactly the right bolt tension. Enough is enough, and too much is too much, and the range given is inside that range.

Half of the bolts in the suspension are problematic for putting a torque wrench on anyway, so just get done up to mechanic tight  and spanner checked a week later.
