Upgrading to larger off-road mud tires, heavy steel bumpers, or suspension lifts puts massive extra leverage and stress on these components. Over high mileage, the factory-installed plastic internal liners naturally compress and wear down. Once the internal socket gains slop, it triggers wandering steering tracking on the highway, uneven front tire wear, and harsh metallic clunking or popping noises when turning over trail obstacles.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003eUnlike sealed, non-serviceable factory alternatives, this original equipment manufacturer (OEM) \u003cb data-path-to-node=\"9\" data-index-in-node=\"96\"\u003eSpicer design is fully greasable\u003c\/b\u003e.
