i have never had a detroit or daily drove a rig with a lunchbox either. but i have driven 1983-hilux's truck with a aussie out back on dirt and on pavement and you could not even tell it was there on pavement.he has daily driven it and wheeled it for over a year with 35's. if i ever buy a lunchbox type new it would be an aussie. i was impressed with his.
im thinking that most of the problem with the lunch box lockers is the clearance specs over time. it might be time to get some new side gear washers to bring them in specs again. with any metal to metal contact there will be wear and adjustment is needed over time.
