john deere 4020 powershift 1965

pdeere · Jul 16, 2009

My 4020 has a popping/grinding noise that sounds like it coming from behind the battery on the right side. It only does it if I am a hill will the left side down the hill or if I turn really hard to the right. Took of the right axle and had a dealer look at it, replaced the bearings. Same noise. Could it be the parking pawl spring, or the bearings on the left side?
thanks ahead of time

Did you or dealer check for loose wheel or axle wedges? I seen loose wedges pop before.

I took the hub and wheel off myself. It was in no way loose. I was wondering if it may be a outer bearing on the left side on the axle.
Thanks for your reply

I also meant did you check the wedges that hold wheel to cast center.

Amazing how this forum works, I have the same trouble with a 64 4020 powershift and was going to write in.
By chance, does yours have the 3ph, but not totally working correctly. I suspected maybe if the load arm is off the cam follower. Maybe it's banging around in the case on hills. Just a theory.
Be sure to update us if you figure it out.

When I start out, it kinda sounds like a racheting action below you feet, under the platform. I have a John Deere mechanic coming over to drive it. Over the phone he thought it may be the parking pawl spring.
