The last new car I purchased went over the break in period and the requirements during that time. They are geared more towards protecting the motor which is more susceptable to problems if it isn't broken in right. People also usually do not go out right away with a new car and drive it hard. I'm not sure which article you are looking at but the biggest concern is the gears wearing in before the teeth set from heat. Because of this you want to stop frequently when they are first installed to give them time to cool down and to keep them from getting really hot. In reality this is best practice since I've seen many gears installed that were abused right away without problems. I did so with the gears in my rearend (I installed them one day and played in the mud the next). Granted when I am out playing we stop frequently though so I doubt that they got really hot that day. I did have them wound up pretty good a few times though flinging mud when it was buried to the frame.red67 said:
When I had mine installed, they said I had to wear off the special coating on the gears that's there to prevent rust. It's possible that automakers don't get that coating since they know they will use them quickly so they are less likely to rust on the shelf.red67 said:
