Over years of highway commuting or trail riding, 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 escalates with vehicle speed. As the bearings degrade, they force the axle shafts to rotate out of true alignment, rapidly tearing through the outer oil seals. Compromised seals allow highly pressurized differential gear oil to weep out onto your rear 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 end 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 alongside two brand-new, high-tensile strength press-fit retainer rings (locking collars). Sourcing a genuine Spicer bundle ensures perfect metallurgical construction and factory tolerances, preventing loose components or premature wheel-end failure. To complete the job permanently, this dual-side service package matches the primary wheel bearings and locking collars with premium multi-lip outer oil seals.\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 Heavy-Duty Press-Fit Axle Shaft Bearing Retainer Rings (Locking Collars)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,2,0\"\u003e(2) Genuine Spicer Premium Multi-Lip Rear Axle Shaft Outer Oil Seals\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 installation time and preventing uneven component 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\"\u003eIncludes High-Tensile Retainers:\u003c\/b\u003e Features fresh press-fit locking rings required to safely secure the axle shafts inside the housing, eliminating the dangers of trying to reuse stretched or distorted old hardware.\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 linings 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 (Dana 44A \/ Aluminum HD) Axles\u003c\/b\u003e. \u003ci data-path-to-node=\"15,0,0\" data-index-in-node=\"92\"\u003eFits standard and Quadra-Drive rear axle configurations.
