  Q: How to Service and Repair a Wheel Bearing on Toyota Echo?

  A:

  You should begin the wheel bearing service and repair work by taking off the front wheel. Check the bearing backlash together with axle hub deviation by removing the Brake Caliper and disc assembly which allows secure support for the brake caliper assembly. Inspection with the dial indicator at the hub axle center requires backlash measurement which should be under 0.05 mm (0.0020 inch) or a bearing replacement becomes necessary. The measurement of axle hub deviation on the hub surface area outside the bolt must be below 0.05 mm (0.0020 inch) while hub axle replacement could be necessary. Reinstall the brake caliper then secure it and put back the disc with the two bolts torqued to 88 Nm (900 kgf.cm, 65 ft. lbs.). Apply Special Service Tool: 09930-00010 and a hammer to unstake the lock nut before removing it while applying brakes. Uninstall the brake caliper with 2 bolts and disc while securely supporting the brake caliper position. The ABS speed sensor bolt needs removal during disconnection when ABS is installed on the vehicle. You must disconnect the steering knuckle from the lower suspension arm by removing its clip and nut before using Special Service Tool: 09628-00011 (09628-00030, 09628-00040, 09628-00050) to proceed with the disconnect. Use Special Service Tool: 09628-62011 to disconnect the tie rod end following tie rod end removal from the steering knuckle after breaking the nuts and cotter pin. The Shock Absorber operation needs the removal of two nuts and bolts together with the axle hub and steering knuckle while avoiding damage to the boot and ABS speed sensor rotor. Begin by putting the steering knuckle along with axle hub onto the shock absorber before applying engine oil to the threads of the 2 nuts and installing them at the shock absorber's lower side using a torque of 132 Nm (1,350 kgf.cm, 97 ft. lbs.). The tie rod end should be connected to the steering knuckle by using a nut followed by a 49 Nm (500 kgf.cm, 36 ft. lbs.) tightening torque, then adding a new cotter pin and enhancing the torque when holes for the pin do not match. The lower suspension arm through the nut connects with the steering knuckle after torquing to 98 Nm (1,000 kgf.cm, 72 ft. lbs.). A new clip receives installation following this nut tightening to 60 degrees when the holes for the clip are misaligned. Install the ABS speed sensor only if your vehicle has this feature by torqueing it at 8.0 Nm (82 kgf.cm, 71 inch lbs.). First install the disc along with the brake caliper and two bolts together, finally torque them to 88 Nm (900 kgf.cm, 65 ft. lbs.). Then install a new lock nut under brake application torque it to 216 Nm (2,200 kgf.cm, 159 ft. lbs.) before using a chisel and hammer to stake the lock nut. Recheck bearing backlash then install the front wheel and torque it to 103 Nm (1,050 kgf.cm, 76 ft. lbs.). Perform several brake pedal depressions before inspecting front wheel alignment along with checking the ABS speed sensor signal if the vehicle is equipped with this system.
