🔧 Wrangler - Control Arm Replacement

On your Wrangler, the control arms locate the solid axles and set caster/pinion angle. Replacing one is straightforward, but the exact steps and torque specs depend on which arm you’re doing (front/rear, upper/lower) because the hardware and access differ.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours (per arm)

⚠️ Safety & Precautions

• ⚠️ Support the frame with jack stands before unbolting any control arm.
• ⚠️ Keep a floor jack under the axle to control axle rotation and prevent sudden movement.
• ⚠️ Do one control arm at a time to keep the axle located.
• ⚠️ Final-tighten control arm bolts at normal ride height to avoid bushing damage (a bushing is the rubber sleeve inside the arm that twists as the suspension moves).
• ⚠️ Wear eye protection when using a breaker bar and penetrating oil.

✅ After Repair

• Drive slowly and listen for clunks, then recheck all fasteners.
