My plan of attack as soon as these new tie rod sets arrive is to install jerk fittings in all four ends. Since the factory outer tie rod ends went bad early on due to no grease in them, I am not taking any chances with these.I tried to turn the no zerk rod ends into greasable ends on my yanmar. It can be done, but still didn't make them last any longer. I ended up finding greasable joints and cutting the old ones off and welding the new one back on. (In hind sight i should have threaded the rods and went that route.) They have been on for years now with no slop that I can notice. I'm planning on doing the same to the kubota when the factory joints are really, really junk. But I'll thread the ends instead of welding them in.
