Got the 86 mobile yesterday. Checked the fluids so I could drive it to the exhaust shop today, found the rear was empty. Thought it was odd, but filled it up. Drove it down the road, seemed good parked it and waited for daylight today. Went out this morning for a trip to the exhaust shop, about 1 pint of gear oil was on the ground by my driver rear tire. I'm assuming axle seal is bad. Never done a 9", I'm reading I pull the axle by 4 bolts on outer flange, then MUST press off bearing to replace seal and of course new bearing and race in the tube? Sound right? What's the best seal? I have a good local bearing supplier (cheap, Timkin normally), anyone know the part number on the 86 9"?
