Suspension & Steering Parts for Jeep Grand Cherokee

Ever since they were first developed during World War II as four-wheel drive reconnaissance cars, Jeeps have had a reputation for easily navigating even the most rugged terrains. Contemporary Jeeps like the Grand Cherokee also sport sophisticated suspension and steering systems that give owners of these iconic vehicles improved handling, stability, and comfort. There are many replacement parts available for this Jeep.

What are some suspension system components?

Suspension setups function to support the weight of your vehicle and its passengers while maximizing the contact your tires make with the surface of the road. Consequently, they are subject to much more stress than other vehicle systems, and components can get worn out more quickly. Suspension systems contain the following components:

  • Tires: tires are pneumatically inflated devices that surround the rims of your Jeep Grand Cherokee?s wheels and are responsible for providing traction over the surface of the roads your vehicle is traveling.
  • Shocks: shocks or shock absorbers are pneumatic or hydraulic cylinders that compress and decompress in order to keep your vehicle from bouncing on the roads.
  • Struts: like shock absorbers, struts perform a damping function, but they also provide structural support and for other suspension components like the leaf and coil springs and help keep the tires aligned properly.
  • Bushings: bushings are rubber or polyurethane cushions that are found on shock absorbers, stabilizer bars, and other steering parts and function to control the movements of the ball joints.
  • Ball joints: ball joints connect the wheels to other suspension and steering components.
  • Linkages: linkages connect the front tires to the steering gearbox.
What is an independent suspension system?

All Jeep Grand Cherokee suspension systems manufactured after 2011 are equipped with four-wheel independent suspension systems. An independent suspension setup is one in which each wheel is able to react separately to bumps or potholes in the road. The movement of one wheel is not dependent upon the movement of other wheels as is the case with rigid axle suspension systems.

Independent suspension systems have a number of advantages:

  • Improved handling and cornering: cornering refers to a driver?s ability to handle a sharp curve. When you come to a sharp curve, you have two options: You can either decrease your speed, or you can compensate for the curve by over-steering slightly. An independent suspension setup uses a transverse-arm linkage in which the maximum distance between the springs is equal to the wheel track of the vehicle. This means that manufacturers are able to use softer springs, which improves the quality of the ride and reduces the need for over-steering on curves.
  • Enhanced stability: since the springs in an independent suspension setup are not connected, when one wheel jogs or bounces, that motion does not affect the other wheels. The axle doesn?t automatically transfer energy from one wheel to another.
  • Reduced weight of vehicle: rigid axle suspension setups are bigger and heavier than independent suspension setups. They?re still practical for trucks, but they no longer suit the needs of today?s drivers who prefer lighter, more maneuverable vehicles.
