• Designed to remove and install front
wheel bearings on FWD vehicles
• Tool can be used with the steering
knuckle still on the vehicle
• Saves the time that would otherwise be
necessary to remove the knuckle and press out bearings
• Saves the time and cost of wheel alignment
OPERATING INSTRUCTIONS
Note - for clarity, the photographs included with these procedures show a steering knuckle that has been removed from the vehicle. It is not necessary to remove
the knuckle to remove and install bearings with this tool set.
PRELIMINARY INSTRUCTIONS
Raise and support vehicle. Remove front wheel and tire, axle nut and outer tie rod nut. Disconnect tie rod. Remove front brake caliper and wire aside securely.
Remove brake rotor. On some models, it is necessary to loosen lower ball joint from the steering knuckle. This prevents damage to the transaxle when remov-
ing the axle from the hub. On all models, remove the axle from the hub and wire aside securely. Do not allow to hang unsupported. Reinstall the ball joint (if
removed).
BEARING REMOVAL
NOTE - The following procedure is typical for FWD vehicles and is intended to illustrate the concept, not to be specific to any particular vehicle. Different com-
binations of adapters and tubes will be necessary for different vehicles. Take care to select tubes that are deep enough to allow the bearing to be completely
removed from the spindle. Also take care to select an installer adapter that contacts the body of the bearing and not the balls.
1. Following the preliminary instructions should have made clear access to the bearing on both sides of the spindle possible. If not, remove parts as necessary
to allow access to the bearing.
2. Remove snap ring and seal from the appropriate side of the bearing (if equipped).
3. Assemble washer and installer to forcing screw as shown in Figure b. Installer should be selected so that it rests on the body of the bearing and will not
contact anything else as it draws the bearing out of the spindle.
4. Install the forcing screw assembly through the spindle with the installer against the bearing housing as shown in Figure c. Select a tube with an inner diame-
ter larger than the outer diameter of the bearing. Select an adapter with an inner diameter that fits snugly into the inner diameter of the tube as shown in
figure f.
5. Assemble the tube and adapter as shown in figures d and e. Assemble a washer to the forcing screw and screw the threaded portion of the forcing screw nut
onto the forcing screw as shown in figure f.
6. Using 2 wrenches or air tools, tighten the forcing screw while holding the forcing screw nut stationary. Light penetrating oil applied between the inner diame-
ter of the steering knuckle and the outer diameter of the bearing may be helpful in reducing the amount of force necessary.
7. Turn the forcing screw until the bearing contacts the adapter at the end of the tube. At this point the bearing should completely clear the inner diameter of the
knuckle. Remove from the knuckle and disassemble the assembly consisting of forcing screw, washers, forcing screw nut and
2 adapters sandwiching the bearing. See figure h.
BEARING INSTALLATION
1. Select an adapter that fits flat over the inner diameter of the knuckle without entering the inner diameter. Assemble the adapter and washer to the forcing
screw as shown in figure j.
2. Position the assembly with the head of the forcing screw facing the inside of the knuckle and place the new bearing against the inner diameter of the spindle
as shown in figure k.
3. Select an adapter that contacts the body of the bearing but has the same diameter as the outer diameter of the bearing or slightly smaller. Assemble the
adapter, washer, and forcing screw nut to the forcing screw.
4. Using 2 wrenches or air tools, tighten the forcing screw while holding the forcing screw net stationary with a wrench. Light penetrating oil applied between
the inner diameter of the steering knuckle and the outer diameter of the bearing may be helpful in reducing the amount of force necessary.
5. Turn the forcing screw until the bearing is completely seated inside the knuckle. Remove the forcing screw and adapter assembly. To complete installation,
reverse preliminary instructions.
