torque specs on rear tire?

I need the torque specs on the rear tire/ axle nut and bolt! Thanks

Normal nut with cotter pin (US models): 50 Nm - 80 Nm (36 ft.lb - 58 ft.lb)
Self lock nut (UK models):                     60 Nm - 96 Nm (44 ft.lb - 69 ft.lb)



p.s. a shop manual is a worthwhile investment

Work to mid-figure`i.e. 65Newts. That way if your torque wrench is out of tollerance you will still be in the ballpark.

Why is there such a wide range specified?  Does it also depend on other factors such as the build year?

When considering torque settings what matters is that the nut/bolt is not so loose it becomes likely to undo itself or allow the components it holds to become loose in use and at the other end of the scale that its not so tight as it become strained and weakened or compromises the components it holds. It therefore  follows that Suzuki have decided that anything lower than 50newts` means the nut is not adequately holding components together and likely to back off and anything over 80newts` strains the bolt or other components and weakens it/them........... There is no optimum figure just a sweetspot, 50nm is as effective and safe as 80nm.

People wrongly assume nuts and bolts etc have to be as tight as possible, this is not the case and one of the reasons why so many owners have problems with oil-filter cover studs striping and shearing.

Another danger arises when inaccurate or uncalibrated torque wrenches are used. This is why as mentioned above its good practise to go for the middle of the quoted figures. Lets say your torque wrench is over or under-reading by up to 15%. If you aim for the mid-value of 65newts`the actual figure will come in somewhere between 55.25 and 74.75newts`and still be within the figures Suzuki quote. From this example you can imagine that if you take the nut up to 80newts`with a wrench under-reading by 15% you are actually at 92newts` and probably doing more harm than good.

Thanks Sledge for the comprehensive explanation!
