description A bearing system (39) for a gas turbine engine (20) includes an outer housing (66) and a first ball bearing assembly (60) disposed radially inward from the outer housing (66) relative a center axis of the outer housing (66). The bearing system (39) also includes a second ball bearing assembly (62) disposed radially inward from the outer housing (66) and positioned axially aft of the first ball bearing assembly (60). The bearing system (39) also includes a resilient member (68) that is connected to the outer housing (66) and compressed against at least one of a first outer race (82) of the first ball bearing assembly (60) and a second outer race (88) of the second ball bearing assembly (62) in an axial direction parallel to the center axis.
