I ordered a 3.92 OEM gears and the provider said they did not have them anymore but sell a replacement set which when I received was a 3.90 set. I am only replacing the rear as they were damaged due to bearing failure. The 3.90 gear I received is 10 teeth on the pinion and 39 on the ring. I have a 4x4 with the stock 3.92 in the front. Is the 3.92 a 12 tooth pinion and 47 pinion? Would that be a problem when running 4x4? I use the 4x4 a considerable amount of time through out the year.

Thank,
