Dodge Stratus (2nd generation): Front Lower Ball Joint Replacement

A worn lower ball joint on a 2nd-generation Stratus shows up as clunks over bumps, wheel play when you rock it vertically, uneven tire wear, and a "wandering" steering wheel. The procedure for the 2.4 L engine (EDZ) does not depend on the engine, since the suspension is common across the generation. Specific torque values are not confirmed in publicly available sources, so the figures below are guidelines and general principles. Check the exact values against the manufacturer's service manual.

Difficulty: Medium Time: 2-4 hours for both sides (longer if the threads are seized) Steps: 13 Tools: Floor jack and jack stands, lug wrench, sockets and wrenches (metric, roughly 15-21 mm), ratchet with a long breaker bar, torque wrench, ball joint separator (fork type or screw type), hammer, penetrating oil, a press or drivers for pressing the joint out and in if needed, a heater or propane torch for seized joints, flashlight.

Part

  • 🔩 Front lower ball joint (left and right), one per side. Available as a separate part and also as part of a complete lower control arm. If the ball joint is pressed into the arm and cannot be removed separately, replace the control arm complete with the ball joint. It is easier and more reliable. At the same time, get new self-locking nuts or mounting bolts if they are single-use

Step by step

13 steps
  1. Park the car on level ground, apply the parking brake, and chock the rear wheels. Loosen the front wheel lug nuts, raise the front of the car, set it on jack stands, and remove the wheel.
  2. Confirm the wear: use a pry bar between the control arm and the steering knuckle to check the ball joint for vertical play, and inspect the boot for tears and squeezed-out grease. Play must be checked with the suspension unloaded.
  3. Apply penetrating oil to the threads of the nuts and bolts that secure the ball joint to the knuckle and the control arm, and let it soak for 10-15 minutes.
  4. If it is in the way, disconnect the lower end of the sway bar link (stabilizer link). This makes access easier and lets you swing the knuckle out of the way.
  5. Remove the clamp (pinch) bolt that holds the ball joint stud in the steering knuckle, or remove the stud nut, depending on the design. Note the position and direction of the bolt.
  6. Free the ball joint stud from the knuckle: spread the knuckle clamp slightly with a pry bar, or knock the stud out with a separator or by striking the knuckle with a hammer (not the stud threads; thread the nut on flush first). Pull the knuckle outward and down to release the stud.
  7. If the ball joint is bolted to the control arm, remove the bolts and take the ball joint off. If it is pressed into the arm, press it out with a press or puller, or remove the whole control arm by undoing its mounting hardware at the subframe and the bushings, and replace the arm complete.
  8. Clean the mounting surfaces of dirt and rust, and check the control arm bushings and the CV axle boots. Replace worn parts right away.
  9. Install the new ball joint (or complete arm). Check that the boot is undamaged and the part is seated squarely all the way. Press it in only with a driver on the outer race, and do not hammer on the housing.
  10. Insert the stud into the knuckle, and install the clamp bolt, nuts, and sway bar link hardware. Snug them by hand first, then lower the suspension onto the wheels so the control arm bushings are tightened under load.
  11. Use a torque wrench to tighten all connections to the manufacturer's specified values. As a guideline, the ball joint clamp bolt in the knuckle and the mounting nuts are tightened to roughly 60-120 N·m (44-89 lb-ft), and the lug nuts to about 135 N·m (100 lb-ft).
  12. Install the wheel, tighten the lug nuts in a crisscross pattern, and lower the car. If the ball joint has a grease fitting, pump it with a grease gun until the boot swells slightly.
  13. After replacement, be sure to get a wheel alignment, otherwise the new ball joint and the tires will wear quickly. Take a test drive to check for clunks and pulling.

Common mistakes and warnings

  • The ball joint is a safety-critical component: if it fails, the wheel loses control. Tighten all connections with a torque wrench, and if you lack the experience and the equipment for pressing the joint out, leave the job to a repair shop. Replace ball joints in pairs on an axle to avoid uneven play and wear. Do not apply heat to the boots or rubber. Heat only the knuckle housing or the clamp lug.
