I have a small leak on my JD 4600 front axle, where the main casting bolts to the first 90° bend. It seems an oil leak right at the swivel part of the "kingpin" on the 4x00's is pretty common, but I haven't been able to find much on this location. Looking at JD Parts it appears there isn't any seal at this joint??? Anyone had this apart or know where I should start for fixing? Bolts are tight, oil level is right at full.
