Experience unparalleled performance with our Mac Auto Parts Rear Wheel Bearing & Seal Kit, designed specifically for 1999-2004 Grand Cherokee and Liberty models. This PTC brand new OEM-style replacement kit includes a high-quality rear axle bearing and lock ring, as well as a rear axle seal. The kit is pre-mounted on the axle, ensuring a seamless installation process, but does require a machine shop to remove the old bearing and press on the new one. Our wheel bearings boast superior features such as high-quality oil seals, integral raceways for proper bearing clearance, and an OEM-approved design, all backed by a lifetime warranty for as long as you own your vehicle. Meticulously crafted from durable steel and compatible with oil lubricants, this kit is a perfect fit for your automotive needs. With dimensions of 76 millimeters in outside diameter and 30 millimeters in bore diameter, this product falls under the category of automotive bearings and is a must-have for your Grand Cherokee or Liberty.
