1. Park your Frontier on level ground and engage the parking brake.
2. Make sure the steering wheel is centered.
3. Locate the torsion bar adjustment bolts on the front of your vehicle. They are usually behind the front wheels.
4. Loosen the locknuts on the torsion bar bolts.
5. Use a wrench to turn the torsion bar bolts clockwise to raise the front end or counterclockwise to lower it. Make small adjustments, about a quarter turn at a time, and check the height frequently to ensure you're achieving the desired level.
6. Once the desired height is reached, tighten the locknuts to secure the adjustment.
7. Repeat the process on the other side of the vehicle to ensure both sides are level.
8. Test drive your Frontier and check that the ride height is satisfactory and the vehicle handles properly.
Note that adjusting the torsion bars can affect your vehicle's alignment, so it's recommended to have the alignment checked and adjusted if necessary after making any adjustments. Also, be cautious not to over-adjust the torsion bars as this can compromise safety and handling.
