To remove the front brake disc, unstake and remove the drive axle hub nut if working on an all-wheel drive model. Then, remove the four retaining bolts and the hub-and-bearing assembly. If working on an all-wheel drive model, use a puller to draw off the hub-and-bearing assembly from the driveaxle. Discard the bolts and replace them with new ones. Clean the mating surfaces of the hub and hub carrier, and position the hub on the carrier. Install the new retaining bolts and tighten them to the specified torque. Reinstall the brake disc. For all-wheel drive models, install the driveaxle hub nut following the proper torque setting.
