Toyota Camry: Rear Suspension Lateral Link and Trailing Arm Bush Collapse

The ACV40 and ACV50 Camry use a multi-link rear suspension with a network of lateral links and trailing arms, each secured with rubber-bonded bushes. These bushes are not rebuildable in the original Toyota design and are pressed into the links at manufacture. With age and mileage the rubber compound softens and cracks, allowing the bush to deflect excessively under cornering and braking loads. The result is rear toe and camber change under load, which presents as unpredictable rear-end movement during directional changes and excessive inner or outer rear tyre wear. The lower lateral link inboard bush and the front trailing arm bush are the most commonly reported failures. Aftermarket polyurethane bush kits are available as an alternative to OEM rubber.

• Rear tyres wearing unevenly on the inner or outer shoulder, faster than fronts, despite correct inflation
• Vague or darty rear-end feel during lane changes at highway speed, as if the rear axle is steering slightly
• Knocking or clunking from the rear suspension during hard braking or when traversing speed bumps at an angle
• Rear wheel alignment unable to be set to specification — technician reports bush movement preventing adjustment from holding

1. 1

   Check for uneven rear tyre wear or a vehicle that crab-walks slightly when viewed from behind at speed.

2. 2

   If a workshop inspection is possible: On a hoist, grasp each rear lateral link and trailing arm and apply firm fore-aft and lateral force — there should be no visible rubber cracking or bush deflection greater than 2mm.

3. 3

   Inspect the bush outer sleeves for rust-jacking where the steel sleeve has corroded inside the aluminium link eye, splitting the rubber.

$450 to $1,600 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.

• “When was the rear wheel alignment last checked and was it within specification?”
• “Have the rear suspension bushes been inspected or replaced, and if so which ones?”
• “Is there any unusual wear on the inner or outer shoulder of the rear tyres?”

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.
