  Q: How are the Steering Knuckle and front Wheel Bearing removed and refitted on Volvo V70?

  A:

  The hub bearing is a sealed, pre-adjusted and pre-lubricated double row ball type with an expected service life of the car for its entire service life without service. The bearing housing, hub flange and the bearing are serviced together as an assembly and cannot be taken apart or renewed separately. To remove the hub assembly, loosen the front wheel bolts, raise the car on its jack and place it on axle stands before removing the front roadwheel. Next, slacken and remove the driveshaft bolt, with an assistant depressing the brake pedal to prevent hub rotation, removing the old bolt for a new one. Undo the nut that holds the anti-roll bar link to the Shock Absorber, counterholding the nut with a torx bit. Remove the ABS wheel sensor and wiring from the suspension strut bracket and undo the bolts holding the brake caliper and lock limiter bracket to the hub carrier, remembering that new bolts will be required for refitting. Slide the caliper assembly off of the disc and suspend it. Check the position of the brake disc against the hub, making a mark if necessary, and then remove the bolt fixing the brake disc to the hub. Free the driveshaft CV joint from the hub flange by tapping it inwards before disconnecting the steering track rod end balljoint from the hub carrier. To maintain the camber setting when reassembling, measure the distance from the hub carrier mounting lug to the back of the shock absorber. Remove the bolts that fix the hub carrier to the shock absorber, note the direction of the insertion of the bolts, then remove the suspension control arm balljoint from the hub carrier, being careful not to damage the dust cover. Swivel the hub carrier assembly outwards and pull the driveshaft CV joint out of the hub flange. Finally, undo the four bolts to pull the bearing housing assembly out of the hub carrier, remembering that new bolts will be needed for reassembly. Before refitting, clean all surfaces of metal adhesive, rust, oil and dirt, find the bearing housing on the hub carrier and refit the new bolts, tightening them in diagonal turn order and to the recommended torque settings and angles. When refitting the hub carrier to the shock absorber, make sure the measured distance is maintained, clean and aligned the hub and brake disc mating faces, lubricate the CV joint threads and driveshaft retaining bolt with engine oil, and make sure the ABS sensor and where it is kept clean before refitting. Finally, tighten all nuts and bolts to specified torque (the driveshaft bolt should be tightened using a torque wrench first and then through the specified angle using an angle-tightening gage).

  Q: How to replace the rear wheel bearing when they are supplied as a complete assembly on Volvo V70?

  A:

  The wheel bearing is supplied as a complete assembly and cannot be renewed separately. Begin by removing the brake disc, then undo the bolt to take out the ABS wheel speed sensor from the hub carrier. Next, undo the four bolts to withdraw the bearing assembly from the hub carrier, keeping in mind that for some models, the lower rear fixing bolt may require partial grinding of its integral flange for removal after the hub is detached. Install the new assembly onto the hub carrier, inserting and tightening the new bolts provided in the bearing/hub kit to the specified torque. Ensure that the bolt without an integral flange, which includes a washer, is installed into the lower rear bolt hole in the bearing housing. Finally, reattach the ABS wheel speed sensor and the brake disc.
