706 axle bearing?

[Farmall 656]

This weekend I got my 706 out of winter storage for the season. As I was driving it out of the shed, I began to hear a pop sound and after investigation, it sounds like it is coming from the end
cap area at the end of the axle. It would make the pop sound every 1/3 to 1/2 rotation but didn't make the sound when turning left or right. I have not had time to tear into it, but can I assume it
is the wheel bearing or is there something else I am not thinking about? Thank you in advance for your experience and advice!!

Check for a loose wheel to rim bolt or bolts. Always check/fix the simple/easy stuff before going deeper.

Yup look at the cast center to the axle then the rim to cast. I've not had trouble with the rims bolts though I have had the ones at the axle in the casting work some. Might also look for a crack from one of the square corners in the center casting outward. I had one crack once was plowing and went over a pile of manure the wheel spun free than hit dirt and made a sudden stop of the wheel rotation. That is when it cracked.

Well if you find that after all the checking everyone gave you , do this make darn sure your park lock is ALL the way UP . Due to ware sometimes the park loc pawl does not come all the way our and can cause a noise that was not there yesterday. . More then likely yours does not have the NEW spring loaded park loc., Any 06-66 that has come thru my shop does not leave till a spring loaded park loc is installed . Those are either IN or OUT and NO run away tractors that i have seen several times with the old over center park loc.

Thank you tractor vet!! I will have to check the park lock. I don't believe I had the park lock on when I had it stored in the shed over winter but I can imagine on the 706 it might have met its life expectancy by now. Can I presume I can get the new spring loaded park lock from my local CaseIH dealer? Thanks again...I always appreciate your insight and experience on these tractors!!
