Honda Vezel: Front lower arm ball joint wear causing bump clunk

The RU-series Vezel/HR-V uses a MacPherson strut front suspension with a pressed-in lower arm ball joint. The ball joint socket is prone to wear of the PTFE liner under the combined loads of NZ/AU road conditions (speed humps, potholed urban streets). Worn ball joints allow the stud to rock under braking and bump inputs, producing a clearly audible clunk or knock felt through the floorpan and steering wheel. Because the ball joint is pressed into the control arm rather than bolted, replacement typically requires the entire lower arm assembly to be renewed rather than just the joint. Delayed repair causes the joint stud to become loose enough to affect steering geometry, accelerating tyre wear and ultimately posing a risk of stud separation under heavy cornering load. NZ AA and VTNZ WoF inspectors commonly fail RU-series Vezels on this item.

• Clunk or knock from front suspension over speed humps and rough surfaces
• Clunk felt when braking at low speed
• Vague or wandering steering feel on straight roads
• Uneven front tyre wear (feathering or camber wear)
• WoF failure for excessive ball joint play

1. 1

   Listen for any clicking or grating during the check.

2. 2

   Inspect the ball joint boot for splits or grease expulsion.

3. 3

   Check for WoF advisory history on the inspection sticker.

4. 4

   If a workshop inspection is possible: With the vehicle on a hoist, grasp the front wheel at 6 and 12 o'clock and apply rocking force to check for ball joint play.

5. 5

   Use a pry bar under the lower arm to check for vertical free play at the joint stud.

Parts involved: Ball joint.

$350 to $850 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 had any recent front suspension work or lower arm replacement?”
• “Any clunking from the front over bumps or during braking?”
• “Does the current WoF report show any advisory or failure for suspension?”

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.
