I am looking for some help with my JD 5510 open cab tractor. It is a four wheel drive tractor and the other day before starting it up, I noticed a puddle of fluid on the ground on the inside of the left front wheel. It looks as if the fluid was leaking from the inside of the hub area. I added fluid to the hub but it quickly ran out so I am assuming the seal is messed up inside. I don't mind removing the hub and taking it in to the dealer to have the parts replaced but I don't really want to pay someone to haul the tractor there and back and have it sit there for 3 weeks. For those who might be familiar with this tractor, is it an easy job to remove this hub? I don't want to take this on if its a real pain or if special tools are needed. I did get a copy of the parts breakdown and it looks to be the same for the 5210, 5310 and 5410. Thanks in advance for any help with this.
