Mitsubishi Delica: Front Lower Arm Ball Joint Wear — Bump Clunk
Front Lower Arm Ball Joint Wear — Bump Clunk is a common suspension fault on the Mitsubishi Delica on the 2007 onward cars, and we rate it major. Putting it right costs $380 to $900 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 18 documented faults on the Mitsubishi Delica.

What you are looking at
Example of the part — not this vehicleA separated lower ball joint: the control arm has dropped and the wheel has splayed out under the guard.
What goes wrong
The CV5W front suspension uses conventional lower control arms with pressed-in ball joints. The ball joints carry significant load given the Delica D:5's elevated kerb weight and high centre of gravity. As the ball joints wear, internal axial and radial play develops in the joint. This produces an audible clunk or knock when the suspension cycles over road imperfections, speed humps, or uneven surfaces. On NZ grey imports, ball joint wear is often accelerated by the quality of NZ sealed roads and gravel surfaces versus the smoother JDM roads the vehicle was designed and driven on. Worn ball joints alter front suspension geometry, causing uneven tyre wear and imprecise steering. A failed ball joint can cause sudden loss of steering control and is a WOF rejection item. The lower arm assembly often requires full replacement as the ball joints are not always available separately from the arm.
What you would notice
- Clunking or knocking sound from front suspension over bumps or rough surfaces
- Clunk felt through steering wheel when parking or manoeuvring at low speed
- Uneven or accelerated inner tyre wear on front axle
- Steering wander or imprecise response at highway speed
- Vehicle pulling to one side under braking
How to check it
Where to look. Front lower control arm ball joint, one per side, at the outboard end of the lower arm connecting to the front hub carrier
Also check the arm-to-subframe bushings for cracking. Test-drive over speed humps and listen for clunks from the front corners. If a workshop inspection is possible: With the vehicle on a hoist, grasp the front tyre at 6 and 12 o'clock positions and attempt to rock it — movement indicates ball joint play. Use a pry bar to load the lower arm upward while watching the ball joint for axial movement exceeding 1 mm.
What it costs to put right
$380 to $900 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Have the front ball joints or lower control arms been replaced?”
- “Has there been any clunking or knocking from the front suspension over bumps?”
- “When was the last wheel alignment performed, and was any unusual suspension wear noted?”

Mitsubishi Delica buyer questions
Is front lower arm ball joint wear — bump clunk serious on a Mitsubishi Delica?
We rate it major and common on the Mitsubishi Delica. The CV5W front suspension uses conventional lower control arms with pressed-in ball joints. The ball joints carry significant load given the Delica D:5's elevated kerb weight and high centre of gravity. As the ball joints wear, internal axial and radial play develops in the joint.

How much does it cost to fix on a Mitsubishi Delica?
$380 to $900 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.
Which Mitsubishi Delica years are affected?
Our research records this fault on the 2007 onward Mitsubishi Delica. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
How do I check for it before I buy?
Also check the arm-to-subframe bushings for cracking. Test-drive over speed humps and listen for clunks from the front corners. If a workshop inspection is possible: With the vehicle on a hoist, grasp the front tyre at 6 and 12 o'clock positions and attempt to rock it — movement indicates ball joint play. Use a pry bar to load the lower arm upward while watching the ball joint for axial movement exceeding 1 mm.
