- Using a lug wrench or a torque wrench, loosen each lug nut on the wheel you intend to remove, but do not fully remove them yet.
- Consult your vehicle’s manual or the chart above to determine the appropriate torque specification for your specific wheel size.
- Attach the appropriate socket to your torque wrench, ensuring it matches the size of your lug nuts.
- Begin tightening the lug nuts in a star pattern, alternating between nuts to ensure even pressure distribution.
- Apply torque gradually, using a steady and controlled motion, until you reach the recommended torque specification.
- Once the lug nuts are properly torqued, double-check each nut to ensure they are all tightened to the correct specification.
- Repeat the process for each wheel on your 2003 Jeep Grand Cherokee.
When to Re-Torque Lug Nuts
It is important to re-torque your lug nuts after driving a short distance (approximately 50-100 miles) following a wheel change or tire rotation. This helps ensure that the lug nuts have settled properly and are still torqued to the recommended specification.
