Over years of daily commuting, heavy towing, or off-road trail riding with oversized tires, the internal rollers of these factory bearings naturally wear down symmetrically. This wear introduces structural slack, which manifests as a low-pitched howling or growling noise from the rear end that increases with vehicle speed. As the bearings degrade, they cause the axle shafts to run off-center, quickly destroying the outer oil seals. Failing seals allow highly pressurized differential gear oil to weep out onto your brake backing plates, ruining emergency brake shoes, contaminating brake pads, and risking catastrophic internal gear failure due to fluid starvation.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003eReplacing only one side usually means the opposite wheel bearing is close to failing as well. This original equipment manufacturer (OEM) master service package eliminates the hassle of ordering individual pieces or multiple kits by bundling two premium tapered roller bearings forged from high-grade steel, heat-treated for maximum fatigue resistance, and precision-matched to factory tolerances. Sourcing a genuine Spicer bundle ensures a perfect press-fit onto your factory axle shafts, eliminating the risk of loose tolerances or premature component failure. To provide a complete, permanent repair, this dual-side package matches the primary wheel bearings with premium multi-lip outer oil seals, heavy-duty press-fit axle retaining rings, and fresh axle shaft backing plates.\u003c\/p\u003e\n\u003cp data-path-to-node=\"10\"\u003e\u003cb data-path-to-node=\"10\" data-index-in-node=\"0\"\u003eKit Contents (Complete Set Overhauls Both Rear Wheel Ends):\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"11\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,0,0\"\u003e(2) Genuine Spicer Premium Tapered Rear Wheel Bearing Assemblies\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,1,0\"\u003e(2) Genuine Spicer Premium Multi-Lip Rear Axle Shaft Outer Oil Seals\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,2,0\"\u003e(2) Heavy-Duty Press-Fit Axle Shaft Bearing Retainer Rings\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,3,0\"\u003e(2) Rear Axle Shaft Flange Backing Plates\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"12\"\u003e\u003cb data-path-to-node=\"12\" data-index-in-node=\"0\"\u003eKit Highlights:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"13\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,0,0\"\u003e\u003cb data-path-to-node=\"13,0,0\" data-index-in-node=\"0\"\u003eComplete Dual-Side Maintenance Solution:\u003c\/b\u003e Supplies exactly enough factory-correct hardware to fully overhaul both the left (driver) and right (passenger) rear outer axle wheel ends simultaneously, saving time and preventing uneven wear.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,1,0\"\u003e\u003cb data-path-to-node=\"13,1,0\" data-index-in-node=\"0\"\u003eGenuine Spicer Forged Strength:\u003c\/b\u003e Precision-manufactured by the industry's benchmark drivetrain supplier to guarantee uncompromised structural integrity, exact metallurgical limits, and a long operational lifespan.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,2,0\"\u003e\u003cb data-path-to-node=\"13,2,0\" data-index-in-node=\"0\"\u003eStops Differential Fluid Leaks:\u003c\/b\u003e Features advanced multi-lip elastomeric seals designed to securely lock synthetic gear lubrication inside the axle tubes, protecting rear brake components from oil contamination.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,3,0\"\u003e\u003cb data-path-to-node=\"13,3,0\" data-index-in-node=\"0\"\u003eRestores Quiet Operation:\u003c\/b\u003e Eliminates outer axle shaft slack to instantly clear up low-speed howling or growling noises caused by pitted, dry, or neglected wheel bearings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"14\"\u003e\u003cb data-path-to-node=\"14\" data-index-in-node=\"0\"\u003eVehicle \u0026amp; Axle Fitment:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"15\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"15,0,0\"\u003e\u003cb data-path-to-node=\"15,0,0\" data-index-in-node=\"0\"\u003eAxle Profiles:\u003c\/b\u003e Semi-Floating Solid Rear \u003cb data-path-to-node=\"15,0,0\" data-index-in-node=\"40\"\u003eDana 35 and Dana 44 Axles\u003c\/b\u003e. \u003ci data-path-to-node=\"15,0,0\" data-index-in-node=\"67\"\u003eFits standard and Rubicon rear axle configurations.
