Removal (GLC & 626)
- Raise and support front of vehicle. Remove the wheel. Raise lock nut tab before loosening. Apply brakes to lock hub and remove drive shaft lock nut. Loosen tie rod end nut and separate tie rod end from knuckle using joint puller (49 0118 850C).
- Disconnect brake line from shock absorber, if necessary. Remove brake caliper assembly from knuckle and support it on a wire. Remove nuts and bolts which couple the knuckle with the ball joint and the shock absorber. Remove knuckle assembly from the ball joint and drive shaft.NOTE: If drive shaft will not separate from the hub, use bearing puller set (49 0839 425C).
- Separate knuckle from wheel hub, on GLC with puller (49 B001 726) and on 626 with puller (49 G030 725). Make mating marks on hub-to-rotor assembly, detach hub bolts, and separate hub from rotor. See Fig 1.
NOTE:
Place wheel hub in a vise with soft jaws to aid disassembly.
