1978 450C crawler/dozer, the track tension adjuster zerk fittings were corroded up so I replaced them with some I bought at Autozone.
I can pump grease in the new fittings & the track DOES adjust as desired, but when I remove the grease gun from the fittings, grease immediately begins to ooze out of the fittings - from around the little ball in the end of the fittings, not around the threads where it is screwed in.
I replaced them AGAIN (with two more from the same assorted fittings kit I purchased at Autozone), those leak also.
I guess these from Autozone are just el-cheapos... maybe some better quality ones from a different parts house or Tractor Supply would work?... or does this require special "high pressure" grease fittings from John Deere?

Either dirt or grit in your grease, or a nick in the ball or its housing - a manufacturing defect. You might try a post mortem with a big magnifier to see if you just got a bad run. Otherwise any zerk should do.
