Pulled the third member and put the backing plates and axles back on. There's only 1/2" clearance. The cross shaft looks to be 7/8" as best I can measure. Axles are still too long. I will need to remove the carrier and the ring gear to get at the thrust block since the cross shaft is under the ring gear. Haven't been into a differential. Yet. Guessing it's time. I am confused. Should the axle shafts be tight against the cross shaft?
