In solid axle vehicles, the control arms are extremely important in keeping the axle in the correct place while you drive. In most front axle Jeeps, there are 4 control arms on the front axle – two “upper” control arms and two “lower” control arms. In Jeeps with coil springs all the way around, like all Wranglers 1997 and newer, there will be 8 total control arms – 4 up front and an additional 4 for the rear axle.
There will be two reasons why you need to remove your control arms: 1) to replace the bushings/replace the control arms due to wear and tear or 2) to upgrade your control arms when adding a lift to your Jeep!
When lifting your Jeep, you will change the suspension geometry of everything. An alignment helps to correct some of this, but the stock control arms are not adjustable. In order to maintain a good level of drivability in your Jeep and properly set the caster of the axle with a lifted Jeep, you will need upgraded control arms.
