Honda Legend: Front Lower Arm Ball Joint Wear at High Mileage

KA9 Legends at 150,000 km and above commonly develop measurable play in the front lower control arm ball joints. On the KA9, the ball joint is a press-fit component within the lower arm casting and cannot be replaced independently on many production variants — the full lower arm assembly must be substituted. Worn ball joints cause vague steering response, clunking over uneven road surfaces, and irregular tyre wear. In New Zealand, advanced ball joint wear results in a WOF inspection failure. At very high mileage the lower arm front and rear bushings typically show concurrent deterioration, making full arm replacement the most cost-effective repair rather than sourcing pressed ball joint replacements.

• Clunking or knocking from the front suspension over speed bumps, potholes, or uneven surfaces
• Vague or loose steering feel particularly noticeable at highway speeds
• Uneven or accelerated front tyre wear on inner or outer edges
• WOF inspection failure for excessive ball joint play measured by the inspector
• Steering pull or tracking wander under hard braking

Check both sides as wear is commonly bilateral at high mileage. Inspect the front and rear lower arm bushings simultaneously as they degrade in parallel. If a workshop inspection is possible: Raise the front of the vehicle securely on stands and check for play in both lower ball joints by rocking the tyre firmly top-to-bottom and side-to-side while feeling for movement in the joint. Use a pry bar placed under the tyre to load the joint vertically and confirm measurable play against the lower arm.

Parts involved: Ball joint.

$380 to $1,100 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the vehicle passed a recent WOF with no suspension advisories or ball joint flags?”
• “Have the front lower control arms or ball joints been replaced, and at what mileage?”
• “What is the current verified odometer reading and is full service history available?”
• “Has any clunking or vague steering been noticed when driving over rough surfaces?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
