Left Torsion Bar Adjuster – Iveco Daily 65C / 70C (1998-2013)
The left torsion bar adjuster for Iveco Daily 65C and 70C, original reference 500365751, is the adjustment component that controls the preload applied to the left front axle torsion bar. On the heavy-duty versions of the Iveco Daily (65C and 70C), equipped with a front suspension system featuring torsion bars and trailing arms, this adjuster plays an essential role: it determines the front ride height and directly affects handling characteristics, front axle geometry and front axle load capacity.
💡 Operating principle reminder: the torsion bar replaces the conventional coil spring. Fixed on one end to the suspension arm and on the other to the chassis via the adjuster, it twists elastically to absorb shocks and maintain the correct ride height. The adjuster allows this preload to be modulated according to vehicle load.
🔧 Reference and compatibility

⚠️ Wear signs: when to replace the torsion bar adjuster?
A worn, corroded or incorrectly adjusted adjuster develops gradually, but its effects on handling are significant, particularly on 65C and 70C versions subject to heavy loads.
- ❌ Vehicle tilting to one side — uneven ride height between left and right sides
- ❌ Insufficient ground clearance at the front left, especially when loaded or descending
- ❌ Bottoming out in corners or on rough road surfaces — sign of insufficient preload
- ❌ Uneven tyre wear at the front due to poor tracking caused by height imbalance
- ❌ Corroded, cracked or seized adjuster observed during underbody inspection
- ❌ Suspension noises at the front left over speed bumps or road irregularities
🚨 A faulty adjuster compromises the entire front axle geometry. Prompt intervention is essential to prevent premature tyre wear, damage to ball joints and bushings, and to maintain vehicle safety when loaded.
🔩 Installation and adjustment tips
🔹 Adjuster replacement must be followed by ride height adjustment: turn the adjuster screw in progressive increments until both sides are at equal height.
🔹 Each adjustment increment provides approximately 2 to 4 cm of ground clearance increase — adjust gradually without exceeding the manufacturer's range to avoid over-stiffening the suspension.
🔹 Check the condition of the right-hand adjuster simultaneously: wear is often symmetrical on high-mileage vehicles or those regularly overloaded.
🔹 After replacement and adjustment, a complete front axle geometry check is mandatory to correct tracking and prevent premature tyre wear.
🔹 Use penetrating oil on the threads before removal; corrosion often makes the operation difficult on older vehicles.
💡 Take the opportunity to inspect the condition of the torsion bar bushings and suspension arm ball joints, components frequently serviced at similar mileages.
