View Full Version : Wheel bearing torue settings

Found some play in rear wheel bearing so decided to tighten it up.
Outcome manual, torque wrench and hub spanner.  Now not being mechanically minded I could not work out how to torque the bearing up to the recommended torque settings.
I settled for doing it by feel.
Do I need to get some hex bar drilled out to take the hub spanner tommy bar?
Any other recommendations for correctly torquing up wheel bearings?

Most people (including some of the stealerships) just fit them buy feel BUT if you really want to torque them to their specific torques then you need a 3/8" drive tube socket (or adapted down to 3/8" drive) as I think they are only meant to be torqued to around 12nm which is stuff all really and you most likly wont get that low on a 1/2 drive.
In the manual it will give the correct torque.

Tis one of these is what you want.
Mine is actually meant for Toyota's or Nissan's and is a little loose but still works.
It is also 3/4 drive and as you can see I have a 1/2 drive reducer fitted and I normally just use the breaker bar and just nip them.
Works for me, I havnt had one fail yet.

assuming your not talking about the cassette bearings used in later discos (and the rangies I think) by feel is good enough...
I always use the following technique
crank the first nut up as hard as I can, spin the wheel for at least 3 rotations then let it coast to a halt. (this settles the bearings so you dont get a dodgy feel for the rest of it)
back the hub nut off 1/2 a turn or more
tighten the hub nut till it just contacts the bearing and starts to offer resistance.
spin the wheel, if it drags back off and repeat the last 2 steps.
once the initial preset is right put the lock washer in place, crank the outside nut on and tighten up to 50nmish (I use the calibrated elbow most times)
then  fold the lock washer over using a small pry bar to make sure it contacts 1 flat fully on each nut and preferabley Not the flat that sits over the tang or the flat of the washer thats on the axle housing.
Ive never lost a wheel either.

Thanks mcrover and blknight
The technique you describe was roughly what I used but I probably did not spin the hub enough!
My main problem is that not being mechanically minded I tend to use the cook book recipe technique
Anyway after some 12,000+ miles I am very happy with the way the 110 is going and it will get some TLC at Colins capable hands in Cairns on Wednesday

if your in doubt about your wheel bearing settings after youve done 5-10 K jack the wheel up and do the "rim rock check" if thats ok drop it back down, finish of the 50Kms that youd usually do before rechecking the wheel nut tenions, check that then lift the wheel up again and then recheck the rim rock.
if it clunks you got it too loose, if you get "notching" or dragging youve got it too tight.

Sound advice, also just to add, you'll soon know if they're to tight, you inbuilt hand thermometer will tell you, warm is good, hot is not so good;)

Must be doing something right!   :p
Use back of hand first then finger tips to check temperatures.  Must admit I did not repeat rim rock check.
There again I am a strong believer in earning my money the way I am good at and paying people who are good at things I am not good at.
I see/hear of too many LR being 'repaired' by people who think they are 'LR mechanics'
It is best to know and acknowledge your weak points as well as your strong points
