i looked at my 4344 to see how similar they are, but from an automotive perspective:
Break the big nut loose that holds the tierod end to the tie rod first, then remove the nut holding them onto the wheel assy. Now with a BFH, strike the point that the tire rod feeds into. mostly 3 hits and it will pop loose. Unscrew and count how many revolutions it takes to get it off. turn the new one on the exact same count. reassemble and tighten it all down.
