John - My apologies - I have only now seen your comment 18 months on!!! Later cars all have been manufactured with altered Kingpins which are specifically for grease lubrication top and bottom. I agree if you have a car wiith an oiler that if you convert to a top nipple, you need to inject oil or similar into it. As mine is set for Grease, then the remote kit just makes it easier to get grease into the top and bottom of the Kingpin assembly Regards
