Kit includes a bearing between hub and direct clutch housing. The case-hardening at bearing surfaces is removed to make further modifications easier. This forward clutch hub and bearing combination shifts the support of the forward clutch hub from the main shaft to the direct housing and sun gear shaft.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003eCompared to OE or other replacement forward clutch hubs, Sonnax extreme duty forward clutch hub kit 34322-02K has an additional .025” thickness designed-in to reduce endplay and provide further endplay adjustment options.
