A vehicle seat adjuster has a first track member attached to a vehicle frame and a second track member attached to a vehicle seat and is movable relative to the first track. The adjuster includes a drive mechanism, having a threaded shaft connected with the second track member, a drive block attached to the first track member, and means for moving the threaded shaft within the drive block, for moving the track members. The drive block is made of a base, an isolator made of a urethane material, and a nut. The isolator fits within an opening on the base, and the nut fits within an opening within the isolator. Each of the components has a bore formed therethrough such that the threaded shaft can pass through the drive block. The isolator and the nut are pivotable within the base component in order to maintain alignment between the shaft and the drive block.
