Over time, continuous heavy towing, high thermal cycles, or aggressive off-road use naturally wears away the specialized friction material. When these internal clutches wear down or smooth out, your differential reverts back to operating like a standard open unit—leaving you stranded with a \"one-wheel peel\" when accelerating on wet pavement, ice, or loose trail dirt. Conversely, degraded or broken clutch tabs can cause the rear end to bind, chatter, or groan loudly during tight cornering.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003eThis original equipment manufacturer (OEM) restoration package includes a complete, factory-sequenced array of premium multi-lip friction discs and precision-ground steel plates to fully rebuild your Trac-Lok carrier.
