| For those who have done the Leader Gear 4.10 swap. What Differential Gear Oil did you use for the initial break-in? What Differential Gear Oil did you use after the break-in? I'm in the process of getting new gears installed and was curious if the Redline GL5 was good enough for the initial break-in. (initial cruising at 10 min / 30 min intervals, and then a fluid swap at 1,000 miles)
I was planning on the Richmond Gear Oil (75 - 140 GL6) for after the break-in.
