How to Replace the Springs in a Nissan Pathfinderby Contributor
The Nissan Pathfinder is a versatile SUV with enough power to handle the tough jobs with style. The springs on the Pathfinder are easy to access and replace. The front and rear springs in the Nissan Pathfinder are part of a MacPherson strut system and can be replaced by any competent home mechanic.
Replacing the Front Springs
Raise the vehicle and use jack stands to secure the wheels.
Take the strut off the Pathfinder and take note of the position of the bolts for ease of reinstallation.
Attach a spring compressor and compress the spring before removing the piston rod nut. This step can be dangerous if the spring compressor is not attached properly. Use caution as the spring coil can cause injury if released improperly.
Take off the upper strut mount, mounting bracket, upper strut bearing and spring seat before removing the coil spring.
Replace the spring, attach the compressor and reassemble the strut. Reinstall the the spring's upper seat, upper seat bearing, strut mount bracket and upper strut mount. Tighten the piston rod nut to manufacturer's specification. Do not over-torque the nut.
Remove the spring compressor and install the strut assembly onto the Pathfinder.
Put the wheels back on, lower the Pathfinder, remove the jacks and stands, before checking the wheels' alignment. Adjust the alignment if needed.
Replacing the Rear Springs
Raise the Pathfinder and securely block the wheels with jack stands.
Support the Pathfinder along the frame with jack stands, and place a floor jack beneath the rear axle.
Remove or disconnect: rear wheels, shock absorbers, stabilizer bar links, lateral control rod.
Lower the floor jack beneath the axle to take the pressure off the coil spring and attach a spring compressor before removing the springs.
Replace the springs and check the other suspension components for signs of wear when reinstalling.
Torque all bolts and nuts to the proper factory specifications. Make sure to remove the compressor once the spring is reattached.
Put the wheels back on the Pathfinder and lower the vehicle before checking the alignment. Adjust the alignment if necessary.
- Buy powder-coated springs. These springs are coated with a rust proofing before the powder paint is applied and baked on. This process makes the spring much more resistant to corrosion.
- Take the pressure off the springs before disassembling. This is potentially very dangerous as the springs carry a great deal of force which is expended when their restraints are released.
