Suspension fault is a warning light that indicates the problems of dynamic air suspension of Range Rover Sport. Leakage and broken sensors are common faults of this suspension system.
How to Fix Suspension Fault on Range Rover Sport? You can fix the suspension fault on Range Rover by repairing the airbag and struts, changing the sensor linkages, replacing the shock absorbers, and repairing the compressor. In addition, replace blocked valves, reset the control module, alter frame height, align wheels, alter control arms, and repair springs and ball joints.
It has complicated internal problems which require instant repair and replacements. By the following methods, you can repair the faults of the air suspension system.
Repair leaking airbags and faulty struts
Airbags are inflatable gadgets that can protect drivers and passengers in sudden collisions. However, defective built-in sensors and malfunctioning electric cords can damage their sensors.
The factory-installed airline rubs against each other and causes leakage. Replace the airbag by disconnecting the power flow of the SUV.
Approach the steering wheels, unbolt the screws with a screwdriver and pull the airbag. Install a new airbag, tighten it with bolts and clear the warning light.
The struts of the suspension can break due to internal leaks, corrosion, and excessive usage. This causes suspension faults in your Range Rover. You can replace them to remove the warning indication.
Adjust jacks under its frame and improve its height. Pull the lug nuts off the wheels and detach them from the frame.
Approach the strut, access three bolts, and release them with a ratchet. Remove the bolt from the engine and free the struts with a wrench.
Add new struts, tighten all bolts with a torque wrench and reassemble the wheels. The procedure can consume around 3 to 4 hours and cost you $155 to $460 for one strut.
Change the sensor linkages
The sensors can calculate the distance between the suspension of the SUV and the road. They send input signals to the module, which runs the compressor and adjusts the suspension settings.
Due to faulty electric flow, they malfunction and causes suspension problems. They change the height of both sides, and you should replace the faulty sensors.
Troubleshoot the codes when the ignition is working. With calibrated tools, clear the incorrect codes and stabilize the height.
The sensors for the Range Rover Sport cost you around $700 to $710.
Pull them from the strut assembly and adjust the new sensors. Connect the electric wires and maintain a connection between the battery and these sensors.
Replace the faulty shock absorbers
Road dirt particles, debris, and potholes can damage the shock absorbers. In addition, they cannot withstand shocks due to internal faults and blockage of oil passages.
It causes internal leaks and malfunctioning compressors. Change the shock absorbers and remove the warning from the display section.
Lift your Range Rover Sport and access the wheel spinning. Under the frame, find the faulty shock absorbers and pull the bolts of the lower shocks.
Find the bolts underneath the hood and remove them from the upper shock absorbers. Push the upper end of the new shock in the top mount.
Adjust the new bolts, rotate them clockwise and adjust the new shock absorber.
Repair or replace the pump/ compressor
The compressor is the central working unit of air suspensions. It is the controlling unit of inflated airbags and regulates their functions.
Due to long-term utilization, corrosion can cover the compressor and causes failure. In addition, the faulty compressor produces loud sounds due to internal wear.
It requires instant replacement, which is expensive due to its complexity. Access a rebuild kit and alter the valves and compression equipment.
Turn on the ignition; remove the electric connectors and wires from the compressor. Pull it outwards, adjust the new compressor and reassemble the electronic components.
Replace blocked air suspension valves
These valves are essential components of the air suspension and can open and close the springs according to the input signs of the electric control unit.
The suspension can sag due to the failure of valves, and they cannot regulate springs. You can access the diagnostic trouble codes of the system.
Underneath the SUV, you can find the valve block on the driver’s side. For replacement and repair, wipe the connector fittings of the valve block with soapy water.
You can fix the suspension problems by repairing the cracks by adding sealing material. Change the valve block by pulling it, removing it from the compressor, and installing a new option.
Reset the control module
You can reset the suspension control module of your SUV by re-adjusting the frame height. For this purpose, uses calibrated gadgets and modify the lever.
You can use the calibrated scanners and clear the old codes. Find the errors of the malfunctioning airbags, internal leakages, and other faults.
Then, disconnect the battery terminals, and leave for 2 to 5 minutes. Finally, reassemble the connecting points to clear the incorrect codes.
Change the height of the Range Rover Sport frame
Sometimes, the height of the suspension changes due to inadequate calibration and maintenance. Hold the rear and front buttons of the suspension to resolve these problems.
Press them for around 20 to 30 seconds and release them. It can bring the settings back to the standard level. However, the button technique results in delayed responses.
You can add a lift kit to your SUV to change the height permanently. However, it also requires service and calibration after a specific time.
Align wheels and change arms
The incorrect alignment of the tires on the Range Rover Sport causes damage to the suspension and triggers the sign. As a result, you cannot handle and stabilize the SUV, and the road pulls it.
With the alignment machine, check the angles of the tires and compare the calculated results with stock values. Take professional help, modify the wheel casters and toes and stabilize the tires.
The control arms connect the tires to the frame of the SUV. They have built-in bushing, which is vulnerable to damage.
They can bend and change their shapes after a particular time. Replace the bent arms for 2 to 2.5 hours.
Approach the arm bushing, remove the bolts, pull it outwards, and discard. Adjust the new control arm, connect it with the tires through bolts and tighten the nuts.
Repair springs and ball joints
The springs can attach the suspension to the frame of the range Rover sport. Over time, they break and lose their work efficiency.
It decreases the frame height of the SUV, and you should replace them instantly because the faulty springs can cause sagging.
Near the bumper, approach the valve block and drain the pressure. Perform it by removing the pressure from both valves. For disconnection, hold the air spring and disconnect the passage.
The older airlines and passages can cause cracking of O-rings. Release the old springs, pull them manually and adjust new options, O-springs, and flow lines.
Ball joints are specific connecting points that absorb the shocks and provide smooth steering at different speeds. The corrosion, long-term use, and internal cracks can damage ball joints.
For their replacement, jack up the SUV, remove the tires, and move the rotors and brake calipers. Remove the sway bars and control arms from the lower side.
Adjust a hammer between the knuckles and ball joint and tap it. Remove the middle springs that secure the ball joints.
Press the older and cracked ball joints and remove them from the control arm. With a ball joint press, install a new option into the control arm and fix it in the mounting spot.
