Last week I swapped out my rear "X" axle for a rubi with 5.13s. Today, I had my front gears for my D30 replaced with same ratio to match. The salesguy told me that I needed to take it easy in 4 wheel drive but not to worry about 2 HI because the gears are not spinning due to open diff. Don't the gears spin in the front diff regardless? I'm pretty sure my front driveshaft spins whether I'm in 4 or 2 wheel drive. Am I missing something?

Everything still spins but there isn't any power being directed to the front end from the transfer case in 2wd when you engage the transfer case into 4 wd then power is being transfered to the front axle.

Okay, that's what I thought. So is the break-in period only when under load? I'm wanting to know if I can drive on freeway right now since rear gears are already broken in

Yup, they move but you'll be fine as there is no load on them.

Do the front gears from a rubi fit the D 30 too ??

No, totally different diameter.
