We have been having issues with the steering on our forklift. It will turn to left without any trouble. Every now and then with no rhyme or reason it will lock up when trying to turn to the right. It is very random when it decides to lock up as well. I have replaced the orbital motor checked to make sure all pressure is within the proper area. I have changed the hydraulic oil and filter, changed the tie rods as they were worn out. I am running out of ideas, does any have an idea of what could be happening? Sorry it's the H60XM model.
