The four wheel drive front axle on my JD4600 started leaking on the front left where the hub assembly bolts to the axle with four bolts. It looks like the bottom 2 bolts are either loosening or they are pulling out. Is this common? Is it possible that they are stripped or do they loosen? It seems that as the bolts pass through a flange and thread into the opposite side that there would be some type of thread locker used to keep them from loosening. Anyone know what the torque rating should be on these bolts? I am guessing the bolt size to be appr 14mm. As I can see a gap opening on the bottom side I assume that all the lubricant has drained out. Is JD Hygard the proper product to use?
