Hyundai Equus Lateral Arm and Ball Joint Assemblys

Hyundai Equus Lateral arm and ball joint assemblys

Starting at $80.95, AutoBuffy stocks 3 lateral arm and ball joint assemblies from Dorman and Mevotech Supreme to fit the Hyundai Equus. This one-piece unit combines the lower control arm and integrated ball joint, connecting the wheel hub to the subframe and controlling fore-aft wheel position. When it fails, steering wanders and tire wear accelerates rapidly.

Signs your Hyundai Equus needs a new lateral arm and ball joint assembly

  • Clunking or knocking noise from the front suspension over bumps or during slow turns
  • Steering wheel pulls to one side or feels loose and vague on straight roads
  • Uneven or rapid inner-edge tire wear despite recent alignment
  • Vibration felt through the steering wheel or floorboard at highway speeds
  • Vehicle wanders or requires constant steering correction to hold a lane
  • Visible play, torn boot, or grease leakage at the ball joint when inspected with the wheel off

Which lateral arm and ball joint assembly should you buy for your Hyundai Equus?

Because the ball joint is pressed into or welded to the arm, you replace both as a single unit — so matching OE geometry and joint load rating to your driving conditions matters. The main decisions are grade level (OE-replacement vs. heavy-duty), whether you need a pre-assembled unit with hardware included, and left vs. right fitment for your specific suspension position.

Replacing a lateral arm and ball joint assembly on a Hyundai Equus

Advanced⏱ 2–4 hoursFloor jack and jack standsBreaker bar and metric socket setTorque wrenchBall joint separator / pickle fork or pressPry bar

Raise and safely support the Hyundai Equus, remove the wheel, and disconnect the ball joint taper from the steering knuckle using a separator tool before unbolting the arm from the subframe. Install the new assembly in reverse order, snugging fasteners to manufacturer specification with the suspension at ride height — never torque lateral arm bolts with the suspension hanging free. A professional wheel alignment is required immediately after the repair.

Frequently asked questions

How much does it cost to replace lateral arm and ball joint assemblies on a Hyundai Equus?
Parts start at $80.95 for a single lateral arm and ball joint assembly on a Hyundai Equus. Most owners replace both sides at the same time, so budget for two units. Add shop labor — typically one to two hours per side — plus a mandatory wheel alignment after installation, which adds to the total cost.
Can I replace just the ball joint instead of the whole assembly on my Hyundai Equus?
On most modern Hyundai Equus suspensions, the ball joint is either pressed in permanently or welded to the lateral arm, making isolated replacement impractical without a hydraulic press and exact replacement joint. Replacing the full assembly is safer, faster, and often costs only marginally more than sourcing a separate pressed-in joint and paying for press work.
Is it safe to drive a Hyundai Equus with a worn lateral arm and ball joint assembly?
No. A failing ball joint can separate completely without warning, causing immediate loss of steering and wheel collapse. At the first sign of clunking, wandering, or visible joint wear on your Hyundai Equus, limit driving to low speeds and short distances only — and arrange replacement as soon as possible to avoid a serious accident.
Do I need a wheel alignment after replacing a lateral arm and ball joint assembly on a Hyundai Equus?
Yes — always. The lateral arm directly sets camber and toe angles on the Hyundai Equus. Even if you reinstall to the same position, disturbing the arm changes suspension geometry enough to pull the vehicle and accelerate tire wear. Schedule a four-wheel alignment immediately after any lateral arm replacement.
How long does a lateral arm and ball joint assembly last on a Hyundai Equus?
Service life varies widely depending on road conditions, mileage, and maintenance. On a Hyundai Equus driven mostly on smooth roads, assemblies commonly last many years; frequent potholes, gravel, or heavy loads shorten that considerably. Inspect the ball joint boot for cracking and check for play at every tire rotation to catch wear early.
Should I replace both lateral arm and ball joint assemblies at the same time on my Hyundai Equus?
Yes, replacing both sides simultaneously is strongly recommended. If one assembly has worn out on your Hyundai Equus, the opposite side has accumulated the same mileage and stress. Replacing both restores balanced suspension geometry, prevents a repeat repair within months, and you only pay for alignment once — making it more cost-effective overall.
