Instructions
This kit is to be used with the 6575 Hub Grappler™ Kit to add hydraulic function to removing and installing
half shaft driven wheel bearings. It is not necessary to remove the knuckle assembly from the vehicle, and,
as a result, wheel alignment is not altered.
Vehicle Setup
Raise the vehicle until all weight is off the wheels and they hang freely.
1. Remove the following components:
• tires
• axle nut
• outer tie rod nut and tie rod
• disc brake caliper - use a wire (or OTC No. 7661 caliper hanger set) to hold caliper out of the way
and prevent damage to brake hose.
• brake rotor
• separate the lower ball joint from the knuckle assembly
2. Lubricate the forcing screw in the tool set.
3. Remove axle shaft from hub assembly. It may be necessary to push the axle shaft from hub assembly.
Use a hub puller (OTC No. 7208A; not included) to push the axle shaft from the hub assembly. See
Figure 1.
4. Use wire to tie the axle out of the way. Do not let it hang free. See Figure 2.
5. Refer to the Hub Grappler™ Application Guide (OTC No. 6575MAN-09) for information on which
adapters to use with your specic vehicle model.
NOTE: If the race from the old bearing is still stuck in the hub, use puller assembly (OTC No. 7503)
with race puller adapter (503896) to remove the race. See Figure 3.
