I too know of no possible way to measure the torque when using an adapter like the one that RN and various other supplier sell. However, mine does fit the nuts really well and beats using large adjustable pliers or other such means.

Another word for that brinnelling is "flat-fu**ed UP". The use of the impact wrench may have seemed like a good idea at the time but that is primarily due to your total lack of experience upon which to base a sound decision.

Also if the caliper mounting bolts or hub mounting bolts are not pristine, it is a good practice to go ahead and buy new ones when ordering the calipers and other parts. Having nice new bolts makes it go back together nicely plus makes future removals a lot easier since those original bolts are already about 15 years old and most likely already degraded.

 

The follwing is copied from Terri Ann's site (http://www.expeditionlandrover.info/...ake_Torrel.htm
) half way down the page... text below. Great and reliable description for when you do not have the ability to apply a torque wrench.

Tighten down the inner hub nut to eliminate all free play on the bearings. Spin the hub and retighten the inner nut to make sure the bearings are seated properly and that there is no free play Back off the inner hub nut one and a half flats of the nut. This will provide the free play needed for the bearings. Add the lock washer and outer nut per the manual instructions.

 

That is basically what I did, just did it by feel. God and tight to seat, move it, loosen up to allow it to spin freely, slightly tighten it back a little. Pretty much by guess and feel.
