My backhoe is two wheel drive, what should I be looking for in the front axle , as far as maintenance, I know there is a center pin but my manual doesn't call it out, any input would be great. Great site very informative
Thanks john

the kingpins on the outside of the front axle has grease fittings that need to be greased everytime before and after you use it
