Tech Insight
Full-float rear axle assemblies use large inner and outer wheel bearings to support both rotational load and vehicle weight. In heavy-duty towing and hauling applications, worn wheel bearings can quickly create wheel-end movement, excessive heat, and premature hub or spindle wear if not serviced properly.
Replacing bearings, races, and seals together ensures proper wheel bearing preload and long-term reliability. During installation, inspect the spindle and hub bore for scoring, discoloration, or signs of overheating that may indicate previous bearing failure or lubrication issues.
