Thanks for the reply npalen. My tractor steering always worked. Until I had the tractor jacked up off the front wheels 4 to 5 weeks. What my tractor was doing was the steering fluid in the power steering reservoir was running hot, and steering fluid in the HSU(steering device under the tractor steering wheel)also was running hot. After weeks trying to figure out what was causing this, I removed the front wheel cylinder, took it to the shop, and the shop replaced all the seals inside the cylinder. reinstall the front cylinder, and my tractor power steering fluid in the fluid reservoir and the HSU was not running hot anymore. After installing the front cylinder, I notice the front wheels was hard to turn, disconnected the cylinder from both wheels, and was able to turn the left front wheel freely left and right manually myself. But the right front wheel was froze, the whole HUB was locked/froze in place and will not move left or right. But the HUB will allow you to turn it around and around. Shot some Greece inside the Hub housing, but still no change. Bumped the HUB with a wood block, no movement at all. The wheel HUB froze up only during the I had the tractor jacked up, working with the overheating power steering fluid issue. Reconnected the front cylinder to only the right front wheel, and the tractor turn that wheel right and left with no problem. What can you suggest to be my next step?? Do I need to unbolt and knock out the whole HUB spindle, to see what may be binding it, inside the Left wheel HUB housing.
