i've already got a tuner. do i need a bearing kit though?

 

Yes you will definantly want to change the bearings/shims the whole nine yards. Otherwise you will have problems later down the road.

 

should i get motive. there $100 cheaper than ford

 

depends on how good the installer is. Some people complain motives whine others say they have never whined once. Richmond gears get a lot of crap apparently they whine non stop and its so annoying. I really dont see anything wrong with motives. I went with ford cuz i learned my lesson about buying cheap crap, like my hypertech chip o man was that a mistake.
