Steps
Raise the vehicle and remove the wheel
Loosen the lug nuts and axle nut while the vehicle is on the ground. Raise and support the front securely, then remove the wheel.
Remove the brake assembly
Remove the caliper fasteners and support the caliper so the brake hose is not strained. Remove the bracket and rotor, and secure the ABS wire out of the way.
Move the strut for access
Disconnect the stabilizer link and release the strut-to-knuckle fasteners. Support the knuckle independently so it cannot drop or pull on the CV axle, brake hose, or sensor wiring.
Remove the axle and hub
Remove the axle nut and axle flange fasteners as required, then slide the axle out carefully without damaging its joints or seals. Remove the hub bolts from the rear of the knuckle and withdraw the hub assembly.
Install the replacement hub
Clean the knuckle mounting face and inspect the axle splines. Position the replacement hub squarely, start its bolts by hand, and tighten them in stages to the Volvo specification.
Reinstall the axle and strut
Guide the axle back into the hub and transmission, then secure its flange fasteners to specification. Reconnect the strut and stabilizer link, ensuring the ABS wire and brake hose remain correctly routed.
Reassemble the brakes and wheel
Refit the rotor, bracket, pads, and caliper using the correct torque values. Install and torque the axle nut and wheel fasteners to the vehicle specification.
Check braking and alignment
Pump the brake pedal until firm, inspect the ABS harness, and verify the wheel turns without looseness or scraping. Have alignment checked if suspension position was disturbed, then road test cautiously.
Check your vehicle’s repair manual for exact specifications and fit.
