If you're thinking warranty repair--No--there are many current and older threads covering the tightening up on the warranty policies. Is this a 3/4" or 1" drive ratchet---from the pics it looks like an adaptor is on the drive square. SO used the "L" prefix in both 3/4" and 1" drive ratchets and they still do.

On the older and current ratchets in these drive sizes they used a fastener thru the selector lever so you might be lucky in obtaining just that part or like plinker mentioned spend $10 for the entire kit.
