Hi, new person in the forum. Really appreciate the information shared in this forum! Have purchased an older e2. Would like to understand what changes were made in later models to make the steering easier? Did they rework the the steering gear; introduce new gearing ratios? If yes, can one of the newer steering gear units (2005+) be retrofitted into a 2000 e2? Can one replace the entire steering rack assembly with one from 2005 and later?
