I replaced the broken grommets with the new ones. I purchased 8 so I would have back ups because I did not feel the new one would last either. I think they cost TOO MUCH but I could not haggle for price.
Just used a car oil filter band type wrench and rotated the sealed burner cap a 1/4 turn. cleaned up the rust and dirty. Replaced it with the new cap and tightened it with a 1/4 turn by hand. Instruction can be found on Maytag gas installation manual. The burners are working well and just like a new range.
