Jeep Liberty Control Arms Parts

The Jeep Liberty is an all-wheel-drive vehicle that was produced from 2002 to 2012. The Liberty offered smooth driving on both interstates and heavy terrain. This smooth ride is possible because of the control arm technology used by Jeep engineers.

What is the purpose of control arms?

Control arms are the part of a vehicle’s suspension system that connects the steering rack to the wheels of the car in the front and connects wheels to the frame in the rear. They facilitate wheel movements up and down by pivoting, an essential function for vehicles built to operate under varying road conditions. Controls also assist wheels in maintaining straight lines of travel while keeping the wheels from moving forward or back.

Are there different types of controls?

There are two different types of control arms, and the two arm designs provide different results. The A-shaped control is an adjustable design that produces a comfortable ride on the open road. The A-shaped arm also serves as a vibration inhibitor through both a ball joint at the wheel end and a bushing at the frame end. The other control design is flat. A flat connection is inflexible and gives a harsher ride while holding the wheels firmly to the road, something you might desire if you enjoy off-road adventures.

What control designs are used in the Jeep Liberty?

Like with the Wrangler or XJ models, the Liberty's control design takes into consideration variable use. The unique application of control designs in the Jeep Liberty provides a smooth ride on the highway and a tighter grip on the surface while driving off-road. Each wheel has two controls for multiple terrains. The front suspension uses two adjustable controls on each wheel. Both controls are of the A-shape design. Upper control arms are designed to allow the wheels to move vertically and reduce vibrations. Lower control arms are designed to hold the wheel in place while reducing harsh impact effects.

The rear suspension uses two adjustable controls. The upper control arm is an A-shape design that reduces vibration and impacts. The rear lower control arm binds the wheels in place and provides pressure to hold the rear tires to the road.

What symptoms indicate a bad control?

Three principle symptoms point to a control issue. The first symptom will be noticed quickly by the driver. A sudden change in feel at the column indicates a control issue in the upper front suspension system. A bend in one control will cause vibrations in the column. If you do not respond to the vibration in the column, the next symptom will be wandering steering. This symptom can indicate a control issue in the front or the rear of an all-wheel-drive vehicle. The final symptom will become evident if you ignore the issues communicated through the column. Loud clunking from any of your wheels shouts control issues.

When should Jeep Liberty control arm parts be replaced?

Have your upper and lower controls inspected for bushing wear when you first feel unusual vibrations through your column. If there is wear, then replace the worn part or the full control itself. Check your controls after every excursion to ensure impacts have not damaged them. Otherwise, it is recommended to update your control arms after every 100,000 miles of use.
