Over high mileage, intensive towing, or hard off-road use, low fluid levels or gear oil degradation cause the tapered rollers to pit, score, or overheat. This wear results in a characteristic deep whining or rumbling sound that changes pitch with vehicle speed, a loose pinion yoke, and compromised gear mesh alignment that can rapidly destroy your ring and pinion set.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003eThis original equipment manufacturer (OEM) kit includes a matching \u003cb data-path-to-node=\"9\" data-index-in-node=\"67\"\u003einner bearing cone and outer race\u003c\/b\u003e (utilizing the industry-standard high-capacity 2872\/2820 footprint).
