While you have it apart do a very almost surgical cleaning of the planetary gear pack. On one side there is a tin shield with a grove behind it . This is the oiler for the little needle bearings in each planetaty gear and it gets micro particals packed in it. I use a dental pick and a tooth brush then air . I've done more of these OD's then I can remeber and clean is the key to having the work perfect for years and miles to come. Tim
