If you operate single or tandem axles that call for L68149 and L44649 bearings with a 1.719\" ID seal, this set gives you matching cups, cones, seals, and the small hardware to finish a hub rebuild correctly. If your spindle dimensions or bearing numbers differ, verify compatibility before purchasing.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can one kit rebuild both wheels on an axle?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
