The pinion gear and bearing on the rear is bad. I know I need to change both the ring and pinion as a set. The ratio is a 3.36 but when I order the set for a 2011 frontier the ring is to large. I think the size is 255mm. The one I have taken off the carrier is 205mm. I ordered one that was 205 mm but then the inside dimension is to small. I matched it up to the old ring and the od is right but the inside is way off. Their is no tags or markings on the rear end housing. The only numbers I can find are the ones stamped on the ring and pinion. All they tell me are the ratio and shim amounts and dates.
Can anyone help me find the right ring and pinon and bearings for this truck. I have just purchase the truck and can't even find the whole rear end in my area.
