Thanks for the reply. Nothing has been done to the rear, so if I understand you correctly, I would just check the rear plug and ignore the front one. If the rear plug shows a normal amount of oil then I would be ok. Do you agree?
I am leaking oil at the front of the 2 speed where the drive shaft connects. It only leaks after I have moved the truck. I didn't understand that until now, but I suppose the oil drains to the rear when the truck is sitting which means there is oil to the front only when the truck is moving. Is that correct? Thanks Allen
