Verify the steering knuckle and rotor configuration before installation, especially on 1977-1980 Jeep CJ5 and CJ7 models that require a steering knuckle with 6 bolts and a 5 stud rotor. Confirm outside diameter, bolt circle, center hole diameter, and thickness against the removed part before assembly.
