Technical Deep Dive
The Nissan Frontier’s 4x4 system is based on a two-speed transfer case, which sends power to the front and rear axles. The suspension consists of a double-wishbone setup in the front and a leaf spring setup in the rear. Common failure points include:
- The plastic impeller in the water pump
- The front axle’s CV joints
- The rear axle’s leaf spring bushings

Step-by-Step Guide
Step 1: Suspension Lift
The suspension lift is a crucial step in preparing your Frontier for off-road use. This will provide the necessary ground clearance to navigate rough terrain.
Step 1.1: Remove the Front Coil Springs
- Use a spring compressor to remove the front coil springs
- Remove the upper control arm bolts and swing the arm out of the way
- Remove the lower control arm bolts and swing the arm out of the way
- Remove the coil spring and install the new lift spring
- Torque specs: 40 Nm (30 ft-lbs) for the upper control arm bolts, 60 Nm (45 ft-lbs) for the lower control arm bolts
Step 1.2: Install the Rear Leaf Spring Spacers
- Remove the rear axle’s U-bolts and swing the axle out of the way
- Remove the leaf spring bolts and install the new spacers
- Reinstall the leaf spring bolts and tighten to 80 Nm (60 ft-lbs)
- Reinstall the U-bolts and tighten to 100 Nm (75 ft-lbs)
Step 2: Tire Upgrade
Upgrading your tires is essential for off-road use. This will provide the necessary traction and durability to navigate challenging terrain.
Step 2.1: Remove the Old Tires
- Loosen the lug nuts using a torque wrench
- Raise the vehicle using a hydraulic lift
- Remove the lug nuts and flat washers
- Pull the tire straight off the hub
Step 2.2: Install the New Tires
- Place the new tire onto the hub
- Hand tighten the lug nuts
- Lower the vehicle to the ground
- Tighten the lug nuts in a star pattern to 120 Nm (90 ft-lbs)
Step 3: Skid Plate Installation
Installing skid plates will protect your Frontier’s underside from damage caused by rocks and other debris.
Step 3.1: Remove the Old Skid Plates (if applicable)
- Remove the bolts holding the old skid plates in place
- Pull the old skid plates straight off
Step 3.2: Install the New Skid Plates
- Place the new skid plates onto the vehicle’s underside
- Hand tighten the bolts
- Tighten the bolts to 40 Nm (30 ft-lbs)
Pro Tips & Common Mistakes
- Don’t neglect to torque the suspension bolts to the correct specs
- Don’t use the wrong type of tire for your off-road adventures
- Don’t forget to install skid plates to protect your vehicle’s underside
