Holden Colorado: Front Leaf Spring Front Eye Cracking

The front mono-leaf spring on the RG Colorado develops fatigue cracks at the forward eye — the formed loop through which the chassis pin passes — under repeated bump loading, particularly when the vehicle is used with a canopy, tray load, or bull bar that increases unsprung stress cycles. A cracked eye can propagate to full fracture, causing the front axle to shift rearward under braking and creating acute understeer or loss of directional control. This is a safety-critical structural failure that has been subject to at least one voluntary recall campaign in Australia.

• Clunking or knocking from front suspension over sharp bumps or driveway lips
• Visible crack or rust staining at the spring eye when viewed from below
• Subtle pull to one side under firm braking
• Uneven front ride height when measured left-to-right
• Creaking noise from front end when articulating in car parks

1. 1

   Clean the area with a rag before inspecting — cracks appear as dark hairline marks often packed with rust.

2. 2

   Check both driver and passenger sides independently.

3. 3

   If a workshop inspection is possible: With the vehicle on a hoist, use a torch to inspect the coiled forward eye of each front leaf spring for cracks running radially across the inner or outer face of the eye.

Parts involved: Rear leaf spring.

$800 to $2,000 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 recall for the front leaf spring eye cracking been completed — can you show me the Holden dealer service record?”
• “Has the vehicle been fitted with a bull bar, winch, or aftermarket snorkel that added front-end weight?”
• “Has the suspension ever been lifted or modified with non-standard springs?”

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.
