My dad gave me a Yanmar 165d that he has had for along time. It has had a problem for quite a few years when backing up you can’t steer it. It steers fine going forward there is only a little bit of play in the steering tie rod ball joints and one side has a tiny bit of in and out play I believe one kingpin was replaced before by his neighbor, so I don’t know that many details. I am having trouble finding parts for this machine. But I was hoping somebody could help point me in the right direction. Thanks for your help
