Default steering issues on a B 26

Hi Y'all,
Newbie to this site but not to Kubota!
My current orange is a B26 and a kx 040
I've owned a B21,L 4400 and a Grand L 4240

I'm having steering issues with my B26. After it warms up it stops turning left. The steering wheel spins left freely If I take the load off it will turn left and at times return to normal No issues turning right. Actual steering is normal so I'm wondering if a seal or O ring is going bad somewhere in the system.Thanks for any help!

The Workshop Manual says replacement of the controller is the only option and there are no serviceable parts inside.

Messicks price is $975

If you are going to have to replace it, then taking it apart is warranted.

How many hours on the machine?

I don't know if the hydraulic cylinder that powers the steering on a B26 is built similarly, but I had a very similar issue on my BX23. The o-rings on the inside of the cylinder on the ram get flat and allow oil to pass by rather than push the ram and turn the wheels. It's a common problem on the BX.

Kubota sold a seal kit for it. I took it apart, replaced all the seals, worked good as new.

I would rebuild the steering cylinder (because it's a cheap rebuild), just to eliminate that possible issue.
Then if it still does it, you'll need to replace the steering controller.
