Decided to save a few quid and take on this Job myself. Just wondering what is the best practice has anyone here carried out this task before?. The tractor is a crystal. The reason the stub axle has to be changed is due to a previous owner welding the Nut. I currently have all bolts removed and have hit a stumbling block trying to get the stub axle to drop down out of the sleeve. Despite repeated blows with a sledge hammer the axle has only dropped about half an inch. To be honest it does not feel right to be taking a sledge to a tractor for any task. But I cannot understand why the axle refuses to drop. Help and advice would be much appreciated. By the way the Hub has to be replaced as well so that allows me to aim the sledge blows on to that. I know it sounds like a rough thing to do.
