How does the front Ring and Pinion properly break in if there is no load applied to it. I have my new front gears in but the front drive shaft is out until the rear is done (New gears are 4:88) this week. If your asking why did I do them separately is because I got a new PR-44 for the front that came already assembled. It was installed over the weekend. Right now the front gears are just coasting along so I don't see how they can get broken in even if the front drive shaft was in without any load but can't put a load on it unless the front is engaged. Am I over thinking this? Is the front not as critical as the rear?
