R&P Knowledge Hub
Stub end spindles are welded to an axle tube when the original spindle becomes bent, worn, or unsafe. The #84 spindle style is commonly used on 3,500 lb axles and requires L44649 outer and L68149 inner bearings.
The 5 on 4.75 bolt pattern is measured across the center of the wheel studs, not between adjacent studs. Confirm spindle dimensions, bearing numbers, and brake flange compatibility before installation.
