1. Coil Springs - A coil spring is basically a heavy duty torsion bar that's coiled around a axles. Coil Spings move up and down asorbing the motion of the alxe and wheel. Coil springs usually last the life of a vehicle, but in a SUV like a XJ there probably has been some action off-road so they can become wore out and at times crack and possibly break.

 

 

 

2. Ball Joints - Ball joints are spherical bearings that connect the control arms to the steering knuckles and are used in almost every vehicle. Ball joints are similar to the socket and ball design of your hip joint. The ball Joint fits into a tapered hole in the steering knuckle and is encased which prevents dirt from getting inside. You have the upper and lower ball joints, the lower ball joints usually being bigger and wear out faster because that's where most of the weight of your XJ rests.

 

 

 

3. Stabilizer (Sway) Bar - Sway bars are sometimes called anti-sway bars or anti roll bars.  There man function is the keep the XJ's body from rolling or " swaying" when you turn your vehicle. When you turn left the body wants to roll right and so on. Now sway bars are very good to have when driving on the street, the sway bar keeps the XJ as flat as possible equally distribution the weight on all four tires. With off road use  sway bars tend to hinder off road performance and limit the axle articulation. That's why some XJ owners have sway bar disconnects.

 

 

4. Stabilizer (Sway) Bar End Links - Sway bar end links connect the sway bar to the front suspension of the Jeep XJ. Replace these with sway bar disconnects to achieve more axle articulation off road.

 

 

 

5. Track bar - The track bar helps keep the front axle centered under the Jeep, and when the track bar mounting points are loose or wore out then say hello to Death Wobble. Also when you Lift your Jeep XJ the geometry of the track bar changes..and I would recommend getting a adjustable trackbar. 

 

 

6/7. Upper and Lower Control Arms - In basic terms the control arms allow up and down movement of he suspension while holding the knuckles, spindles and axles firmly onto the car. Now alot of people with XJ's who want to add a suspension lift, or just want more tuneability install adjustable control arms. Giving the owner the ability to adjust wheel camber. Positive camber means that the top of the wheel is tipped outward away from the center of the vehicle and negitive camber the the top of the tire is tipped inward.

 

 

 

 

8. Steering Knuckle - A steering knuckle is that part which contains the wheel hub and attaches to the suspension components. The wheel and tire assembly attach the hub of the knuckle where the tire and wheel rotates.

 

 

 

 

9. Pitman Arm - A pitman arm is a metal arm that connects the steering box to the center link also known as steering Linkage. For those that install a lift kit on there XJ alot of them install drop pitman arms to correct the steering geometry.

 

 

 

10. Center Link - The Center link is attached to the pitman arm. When the steering  is turned left or right the pitman arm moves, in turn so does the center link. The center link is connected to right wheel of your XJ.

 

 

 

11. Steering Damper ( Steering Stabilizer ) - The Steering Damper is a hydraulic device simular to a shock absorber and is attached to the steering linkage to absorb the road shock and steering kickback. 

 

 

 

12/13. Tie Rod and Tie Rod Ends -  Tie rods play a crucial role in your steering system. Without tie rods, your steering system would fail. Tie rods are the pivot point between your steering system and your steering arm and wheel. The outer tie rod end is adjustable. This means that you can change the length of the tie rod to fix your vehicle’s alignment. They are responsible for moving your wheels when you steer and for making turning possible.
