one frequently over looked maintenance item is grease for the ball joints and universal or U-joints in a cars suspension
as a general rule, youll want to inspect those adding grease to those components at each oil change, if required,
a good high temp moly grease does a good job, but theres synthetic grease that also works fine.
most new cars will not have the required zerk grease fitting factory installed as some just have plugs other have sealed ball joints that must be replaced if they run out of grease, but most replacement ball joints have the zerk fittings or plugs allowing them to be used
