What causes a broken axle? If your car shocks are becoming worn, hitting any bump or pothole in the road could cause damage to your car axles. Because the axle is constantly rotating and flexing to accommodate different road conditions, it can wear out and fail, resulting in a broken axle.
Registered. If you jack up just one rear wheel and it spins freely, then it’s an open differential. If you jack up just one rear wheel and it does not spin freely, then it is some sort of locking or limited slip differential.
A front axle disconnect is a gearbox unit mounted against the front oil pan on the front passenger side that allows the driver to disengage from four wheel drive / all wheel drive to rear wheel drive.

A 4×4 actuator is an electronic device used to engage the front differential on a so-equipped, four-wheel drive vehicle. On other types of vehicles, the operator is required to turn or push a switch on the vehicle’s dash in order to activate the front axle of the vehicle and the four-wheel drive system.
The Axle Actuator is a device which activates the front axle when the driver switches from 2 wheel drive to 4 wheel drive. When the switch is turned on, the control module turns on an air-pump which is mounted near the front of the car. The pump begins to build pressure and eventually opens a relief valve.
The “Service 4WD System” message indicates a problem with the 4WD system that should be properly diagnosed and repaired. When the ignition key is turned from OFF-RUN-START and is released back to the RUN position after the vehicle starts, the 4WD warning light should go on for 1 to 2 seconds and then go out.
You will know your 4WD actuator is bad when the 4WD (either 4H or 4L) becomes difficult to engage, gets stuck, or fails to activate. Any of these symptoms means that your actuator is faulty and it should be checked immediately.
