Torque Request

the collar nut holding the wheel hub onto the axle.
2009 X5 4.8i

I read 320 ft-lbs but that seems excessive.

Sounds about right.

Isnt that a 36mm nut? Doesnt seem excessive.

If your torque wrench doesnt go that high, weigh yourself, then slide a pipe over a breaker bar. Do the math....x inches from the nut: stand.



Or like I used to do on old VW bugs: A one pound lump hammer and a cold chisel on the enge of the castellated nut: one swing, all your 16 year old might is exactly 256 ft lbs.
