Nissan Frontier Pro 4X
It has a M226 rear axle. Which on this truck is leaking gear oil out of the axle shaft seals.
Nissan, in their infinite wisdom, does not sell such a seal, or even the bearing and retainer behind said seal that must be pressed off to replace the leaker.
No, you have to buy a $300.00 axle shaft assembly. PER SIDE.
Apparently its enough to take a truck from possible used car lot fodder, to WHOLESALE in a hurry. Sort of a shame, its a 2013 with 50k miles and besides that its a set of new tires away from being a nice truck.
