Tools and Safety Preparation
Required Tools and Workspace
Gather a floor jack, axle stands, torque wrench, breaker bar, lug nut wrench, pry bar, hammer, and new hub 03 components. Choose a level surface and engage the parking brake before you start.
Personal Safety Measures
Wear safety glasses and gloves, and make sure the vehicle is securely lifted and supported. Never rely on a jack alone; always use axle stands for stability during the hub replacement.
Removing the Old Hub 03 Assembly
Wheel and Brake Caliper Removal
Loosen the lug nuts while the vehicle is on the ground, lift the front axle, remove the wheel, and carefully unbolt the caliper. Support the caliper with wire to avoid stressing the brake line.
Disconnecting Steering and Drivetrain
Separate the tie rod end from the knuckle and unbolt the lower control arm. This provides enough movement to push the hub outward and safely extract the worn hub 03 assembly.
Installing the New Hub 03 Assembly
Pressing and Fitting the New Hub
Use a proper press to seat the new hub 03 into the knuckle, ensuring it is flush and correctly aligned. Verify that the splines and mounting holes line up before tightening any fasteners.
Reassembly and Torque Sequence
Reattach the lower control arm, tie rod end, and caliper, following the factory torque sequence. Tighten all nuts and bolts to the specifications in your service manual to prevent vibration or misalignment.
Testing and Final Inspection
Road Test and Alignment Check
After rotating the tires if needed, perform a low-speed test and then a highway check for any noise or steering feel changes. Schedule a wheel alignment to ensure tire wear and handling remain optimal.
FAQ
Reader questions
How do I know if my hub 03 needs replacement?
Look for clicking or grinding noises when turning, loose steering feel, uneven tire wear, or visible play when rocking the wheel at the top and bottom.
Can I replace only the bearing inside hub 03?
Yes, if the outer race and housing are in good condition, replacing the bearing and seals can be more cost effective than buying a full hub 03 assembly.
Do I need an alignment after replacing hub 03 on my Durango?
Yes, because wheel positioning can shift during the replacement, and an alignment helps maintain predictable steering and tire longevity.
What torque specs should I use for the hub 03 mounting bolts?
Follow the factory service information for your model year, but typical values fall in the range of 90–120 lb-ft for the outer flange, using a crisscross sequence.
