Just go to Lowes and warranty it and get a new one. The old danaher are nothing special or even very good ratchets they are USA and we're made in Texas I believe that's all it's got going for it the low tooth count is out dated go get their new fine tooth 72t ratchet you will love it way more only downside is they are made in Taiwan. Should be a no brainer I'd never want a rebuild kit for a store brand ratchet I don't even think the offer rebuild kits and definitely would not have one for a ratchet that old. The first kobalt tools by Williams are the best kobalt I have a ton of them and the sockets are as nice as snap one and we're made in the same plant that is now no longer there. The Williams kobalt ratchets are the same inside as the older 936 snap on ratchets I have swapped the guts before and compared everything all the same but gear has an indention on the bottom on one of them but makes no difference. I have some danaher kobalt and it's all the exact same as craftsman's from the time ,when kobalt switched from Williams to danaher it was a huge downgrade IMO but now Lowes is finally getting better tools although Taiwan made they are still very nice and now's the time to trade that sucker in you will be very pleased I promise.
