I am following the recommendation on the Marlin page. Driving easy and doing a 20 mile drain, and a 500 mile drain.
2 questions?
1. What does taking it easy mean? The diff gets pretty hot under normal highway use. Is cruising down the highway at 70mph ok? It would be pretty difficult to put the miles on my truck otherwise. And they say no hard acceleration, well its a Toyota and it doesn't do any hard acceleration, despite my attempts to try. I assume this means no WOT in 1st gear. What about passing on the highway at 1/2 throttle?
2. How do you break in a front diff? I can't drive in 4wd on the street so how do I put the necessary miles on it?
