I just completed the 100 hour service on my BX-23. After checking the torque on the front wheels, I noticed the bolts had slipped by as much as 2-3 turns. I've never seen this much slippage on my cars (1/2 turn at most) and therefore was a bit surprised to see it on the Kubota. The rears were still at the correct torque spec.
Torque was to spec during the 50 hour service, so the slippage must've occurred recently. My only explanation is that I've been running in four wheel drive for at least the past 50 hours (lots of dirt work) and the stress on the front wheels must've been higher.
My torque wrench is calibrated properly, as verified on the rear wheels and three other vehicles in my garage.
Anyone experience this?

It isn't commmon if tightened properly but it can happen. The front tires with the dirt work probably added some stress to them but they should stay tight now that they have been retorqued.. ....

If it continues to happen I would replace them with new as the bolts will continue to elongate if they are defective (not properly heat treated or incorrect material). ....
