The problem that I've experienced on several gearboxes is that the lock plate on the pinion nut fails, and the nut loosens up. This usually results in the bearing getting loose and eventually coming apart. Loctite would help. I had one pinion shaft drilling its way through the rear cover.
We were discussing transmissions on the vSAAB list and Chris Moberg pointed out that the aluminum gearbox case expands and contracts quite a bit. He sets his ring and pinion backlash over-tight initially, so that when things warm up and the gearbox expands, the gears are running at spec. Chris also speculated that the steel case that the competition department used on rally cars may have been developed specifically to counter the aluminum expansion problems.
