When riding with my wife's M3W I found that steering was much more heavy as with mine.
Jacked up both vehicles and there was an enormous difference.
Found out that three of the four king pins where almost frozen in their housing.
What the reason was for this I really don't know.
When I ordered new ones my dealer told me that MMC only delivers the king pins including new arms ?!
I only installed the new king pins so anyone interested in new arms ?
This new king pins improved the steering in a huge amount.
That's strange because the MMC parts list shows those axle pivot ball joints have an individual part number A150002, and are not part of a kit. The rubber covers are listed seperately as well under part # SP160001.
