I have an older model L2800D tractor and the front left tire has a wobble. I can't tell if it's the tie rod or the steering arm (pitman?) or something worse. Anybody have any of the same issues? The tractor is on a ranch in South Texas and I'm hoping to fix it myself and not have to bring it to the dealer in Kerrville. Its not something that's visible to the naked eye. Any help would be greatly appreciated.
