  Q: How to replace the wheel bearings and wheel hub on Volvo 740?

  A:

  The front wheel bearings on front drive vehicles are not adjustable and if the lateral amount of run-out on the hub with the disc removed is greater than 0.0007 inch (0.020mm) then the hub will need to be replaced. To remove and install components on 850, 870, C70 and V70 models, first raise and safely support the vehicle before removing the wheel. Disconnect the ABS sensor from the axle shaft without disconnecting the connector and hang it out of the way. Next, remove the caliper, carrier and rotor, making sure to hang the caliper safely. Proceed to remove halfshaft, separate Ball Joint from the Control Arm and disconnect the sway bar link. Remove the 4 bolts holding the hub and extract the hub. For installation, clean the axle shaft and the hub mating surface and clean the ABS sensor with a soft brush. Install the new hub, tightening the bolts one by one, to 33 ft. lbs. (45 Nm) + 60 degrees. Insert the axle shaft into the hub, fit the splines and tighten the new axle shaft nut by hand. Connect the ball joint to the control arm with new nuts and then connect the sway bar link. Install the brake rotor, carrier and caliper, tightening the axle nut to 89 ft. lbs. (120 Nm) plus an additional 60 degrees, using tool 5461 or an equivalent to counterhold, and lock the axle shaft nut with a chisel. Clean the ABS sensor and its seat and tighten the sensor to 84 inch lbs. (10 Nm) and then install the wheels and lower the vehicle.

  Q: How to check and service wheel bearings on Volvo 740?

  A:

  To check for wheel bearing play, lift the vehicle and support it safely then rock the wheel at the 12 and 6 o'clock positions, if there is movement the wheel bearing should be serviced. For noise inspection, hold up the wheel off the ground and spin it by hand to listen if there is any noise, if it is still noisy after adjustment, it requires the wheel bearing to be replaced. The front wheel bearings on rear drive vehicles are not adjustable and if the lateral run-out on the hub is greater than 0.0012 inch (0.030mm) with the disc removed, the hub should be replaced. To remove and install, the first step is to raise and support the vehicle, remove the wheel(s) and brake caliper, remembering to hang it safely. Pry off the grease cap, remove the cotter pin and castle nut and extract the hub and brake disc assembly, using a bearing puller if necessary. Carefully tap out the grease seal and inner bearing race, and remove the outer bearing race. For installation, press in new inner and outer bearing races and pack the wheel bearing with grease and make sure the inner bearing seal is in the correct location. For hubs having separate brake discs, push the sealing ring against the spindle and install the inner bearing and sealing washer. Reinstall hub, outer race, castle nut and adjust bearing pre-load by spinning hub while tightening center nut to 42 ft. Ib (57 Nm), loosening half turn, tightening by hand to 12 inch lbs. (1.4 Nm). Install the cotter pin, making sure it is aligned with the spindle, then the protective cap, brake caliper, wheel and, finally, lower the vehicle.
