I took The spendle or stearing knuckle off the car. I need to change the wheel bearing.I can't seperate the hub from the rotor. The 4 bolts between the brake rotor and dust shield are impossible to get a wrench or ratchet square on the bolthead. You can only fit a wrench on the bolthead cockeyed or angled. It is a 1994 mercury Capri front wheel drive 1.6 liter dohc 4 cylender. Trying to change the front passenger side wheel bearing.I can't get the 4 bolts out to seperate the hub and rotor.

Thank you for the diagram. I am still unable to get to the 4 bolts that hold the rotor to the hub, the way they are positioned make it impossible to reach by normal wrenches. Is there a special tool needed?

It looks like the hub nut needs to be taken off, then the hub and rotor can come off as an assembly.

FRONT BRAKE ROTOR

Removal

1.
Raise and support front of vehicle. Remove wheel. Unstake drive shaft nut tab. Remove and discard drive shaft nut. Separate tie rod end from knuckle.
Disconnect brake hose from strut (if necessary). Remove brake caliper from knuckle, and wire out of way. Remove nuts and bolts holding ball joint and strut to knuckle assembly.
Remove knuckle assembly from ball joint and drive shaft. If binding occurs, use a dual-jawed puller to force knuckle assembly from drive axle shaft.
2.
3.
NOTE: Hub and rotor are a matched and balanced assembly. Before removing rotor, locate paint or etch mark indicating proper hub-to-
rotor alignment. If marks are not visible, mark hub and rotor for assembly alignment. Failure to properly align hub and rotor can
result in an imbalance condition.
4.
Using a puller, separate knuckle from wheel hub. Retain original outer bearing preload spacer to maintain bearing preload setting. If replacing bearing, install appropriate spacer to adjust bearing
preload (if necessary). See FRONT WHEEL BEARINGS under REMOVAL & INSTALLATION. Scribe match marks on hub and rotor. Remove rotor bolts. Separate hub from
rotor.
Installation

Align reference marks. Install rotor onto hub. Tighten bolts to 33-40 ft. Lbs. (45-54 Nm). Press knuckle and preload spacer into wheel hub. To complete installation, reverse removal procedure. Tighten NEW
axle shaft lock nut to 117-175 ft. Lbs. (159-237 Nm).
