speaking of 9" ford rears,
1. should new gear sets NOT be broken in with synthetic oil like they say for engines, or is it good to break in gears with synthetic.
2. Also, when installing the axles, once the splines engage should the bearings be tapped into place with a little hammer on the end of the axle, or should they be drawn on with the retainer plate bolts?
3. Also, should any grease or sealer be smeared around the outer race beforehand or do those suckers go in dry?
Does anyone have any thoughts on any of these questions?
The people at Currie told me I should never use synthetic gear oil in my 9" Trac Lock, do you agree?

Nothing like reviving a year old thread.
