Installed these on my 2003 F-350 6.0 Powerstroke Diesel engine, installation was easy, up to 165 ft lbs of torque was not available Problems - good quality of the aftermarket of the nut. To update. I've had them installed for two weeks now and have been towing my camper with them, I tightened them today and none of them have come loose and still hold the wheels like bearings. I am impressed
