R&P Knowledge Hub
A stub end spindle is welded to an axle tube when the original spindle becomes bent, scored, or unsafe for continued use. Proper spindle alignment is critical for bearing life, brake performance, and tire wear.
Standard 3,500 lb axles commonly use a #84 spindle configuration with L44649 outer and L68149 inner bearings. Confirm spindle dimensions, brake flange compatibility, and bolt pattern before ordering.
