A carrier assembly includes an adjustment member with a threaded attachment surface that is threadably attached to a mating threaded surface of a housing. The threaded attachment surface is formed on the adjustment member between first and second pilot surfaces, which allows the adjustment member to be selectively rotated to adjust a position of the adjustment member relative to the housing to set a desired carrier characteristic without requiring shims or spacers. The adjustment member also includes a splined outer surface that engages a splined lock member to lock the adjustment member to the housing once the desired carrier characteristic has been set.
