On my Mark the bearing is seeping a little and I have been advised to swap it out. Also advised to change out as a unit....I understand I could press out the bearing but advised again it would be more cost effective to swap the units (cause I will do both sides)......All this being said I can't find a P/N for the whole unit, no problem for the bearings.....It was mentioned to me Dorman 698-412 and 698-413 will work.....My problem is these are for a 2006-2010 Mercury suv.....I would really appreciate ANY light you could shed on this.....If it's just seeping should it be swapped out or should I just monitor it?. ...............Bruce L.
