Symptoms & Diagnosis

Warning Signs of a Failing Rear Upper Control Arm

  • Clunking or rattling noises coming from the rear suspension, especially when going over bumps.
  • Uneven tire wear, often on the inside edge of the tire.
  • A feeling of looseness or instability in the rear of the vehicle, especially when cornering.
  • Difficulty maintaining a straight line while driving.
  • Visible damage to the control arm, such as bending, cracking, or excessive rust.

Testing the Rear Upper Control Arm

  1. Visual Inspection: Carefully inspect the control arm for any signs of damage, such as cracks, bends, or excessive rust. Also, check the bushings for wear or damage.
  2. Shake Test: With the vehicle safely supported, grab the wheel at the 3 and 9 o'clock positions and try to rock it back and forth. Excessive play could indicate worn bushings or a loose control arm. Repeat this test at the 12 and 6 o'clock positions to check for other suspension issues.
  3. Pry Bar Test: Use a pry bar to gently apply pressure to the control arm bushings. Look for excessive movement or play, which indicates wear.

Common Failure Causes

  • Normal Wear and Tear: Over time, the bushings in the control arm can wear out due to age, exposure to the elements, and constant flexing.
  • Impact Damage: Hitting potholes, curbs, or other objects can damage the control arm, causing it to bend or crack.
  • Corrosion: Rust can weaken the control arm, making it more susceptible to damage.
  • Loose Fasteners: If the bolts that secure the control arm to the vehicle are not properly tightened, the control arm can move and cause damage.

Buyer's Checklist

What to Look For When Buying

  • Material: Ensure the control arm is made of high-quality steel or aluminum.
  • Bushings: Check the quality of the bushings. Look for durable materials that can withstand wear and tear.
  • Welds: Inspect the welds for strength and quality. Poorly done welds can lead to premature failure.
  • Finish: A good finish, such as powder coating or paint, can help protect the control arm from rust and corrosion.

Quality Indicators

  • Reputable Brand: Choose a control arm from a well-known and respected manufacturer.
  • Positive Reviews: Read reviews from other customers to see what their experiences have been.
  • Warranty: A good warranty indicates that the manufacturer stands behind their product.

What's Typically Included

  • The control arm itself.
  • Bushings (usually pre-installed).
  • Sometimes new mounting hardware (bolts, nuts).

Installation Overview

Difficulty Level and Estimated Time

  • Difficulty: Intermediate
  • Estimated Time: 1-2 hours per side

Special Tools Needed

  • Socket set
  • Wrench set
  • Torque wrench
  • Jack and jack stands
  • Wheel chocks

Critical Steps and Tips

  1. Loosen Lug Nuts: Before lifting the vehicle, loosen the lug nuts on the wheel.
  2. Raise and Support Vehicle: Use a jack to raise the vehicle and securely support it with jack stands.
  3. Remove Wheel: Remove the wheel.
  4. Disconnect Sensors/Lines: Disconnect any sensors or lines that may be attached to the control arm or nearby components.
  5. Loosen and Remove Old Control Arm: Use a socket and wrench to loosen and remove the bolts that secure the control arm to the vehicle. Penetrating oil can help loosen stubborn bolts.
  6. Install New Control Arm: Install the new control arm and tighten the bolts to the manufacturer's specified torque.
  7. Reconnect Sensors/Lines: Reconnect any sensors or lines that were disconnected.
  8. Reinstall Wheel: Reinstall the wheel and tighten the lug nuts to the proper torque.
  9. Lower Vehicle: Lower the vehicle to the ground.
10. Final Torque: Double-check the torque on all bolts and lug nuts.
