Installation Notes and Tips

Verify rear axle and shoe configuration before ordering, especially on 1990 Jeep Cherokee applications with Dana 44 axle notes and 1984-1989 Jeep Cherokee or Wagoneer models with 2 1/2-inch rear shoe specifications. Confirm drum diameter, bolt circle, center hole diameter, and overall height against the existing part before installation. Inspect brake shoes, wheel cylinders, and hardware condition during service so the new drum can seat properly and deliver even contact.
