Detailed Description

This brake drum is engineered for rear axle applications on 1974-1978 Jeep Cherokee, 1974-1978 Jeep J10, 1974-1978 Jeep Wagoneer, 1979-1983 Jeep Cherokee, 1979-1988 Jeep J10, 1979-1981 Jeep Wagoneer, and 1984-1991 Jeep Grand Wagoneer.

What This Brake Drum Helps Address

• Rear brake pulsation caused by worn or out-of-round drum surfaces
• Reduced braking consistency from excessive drum wear
• Brake noise related to damaged or uneven drum friction surfaces
• Service issues on Jeep Cherokee, J10, Wagoneer, and Grand Wagoneer rear drum brakes
• Fitment problems when the existing drum no longer meets discard diameter limits

Installation Notes and Tips

Verify the drum diameter, bolt hole quantity, bolt circle diameter, and hub register before installation. Measure the existing brake drum against the discard specification of 11.060 in. / 280.900 mm and confirm rear axle fitment on the vehicle. For best results, inspect brake shoes, wheel cylinders, and related hardware during service so the new drum seats evenly and the braking surface wears properly.
