Kubota M7040 4wd Turning Issue

KB7722 · May 28, 2017

Hi all. I've been surfing on here a while getting some good info on issues as they have come up, but this the first time post for me. Thanks all for your hands-on knowledge. Hope I can be of some help at some point as well.

I recently bought a used M7040HD 4wd. I have noticed that when turning left the turning radius is much greater than when turning right. I would say there is 30 to 50% difference in turning radius between the two directions. Before I realized just now reduced the steering angle was when turning left I thought this maybe a design issue but know I think there must be a mechanical issue. Any of you Kubota 4wd owners have this issue before?

Thanks for the inupt!

Never experienced this on my 8540. Check to make sure that when the rack is centered the wheels are actually pointed straight. Also check the toe in. Sounds like something is out of alignment

I don't notice anything like that on my M7040.

The wheels physically turn sharper to the right than to the left.

I had thought about the rack being shifted. Seems like a good place to start and easy to check. Will look there first.

I guess something hanging in one of the steering knuckles comes to mind next. Really don't want to dive off into that just yet.
