Hi, well, all three gears are made of the same 8620 steel, so strength will be the same. For the most part the Yukon's are the quietest running gears besides AAM. The break-in procedure is very important. The main thing is not to build to much heat into the gears. The first 500 miles should consist of short trips with a cool down period every 15-25 miles. You should not tow anything for the first 500 miles. The oil should also be changed after the 500 mile break-in period.
Thanks, Ron
