Torsion bar tensioner left - Iveco Daily 65C / 70C (1998-2013)

The left torsion bar tensioner for Iveco Daily 65C and 70C, original part number 500365751, is the adjustment component that controls the preload applied to the torsion bar of the left front axle. On heavy versions of the Iveco Daily (65C and 70C), equipped with a torsion bar and trailing arm front suspension system, this tensioner plays an essential role: it determines the front body height and directly conditions roadholding, front axle geometry and load capacity.

💡 Operating reminder: the torsion bar replaces the conventional coil spring. Attached on one side to the suspension arm and on the other to the chassis via the turnbuckle, it twists elastically to absorb shocks and keep the body at the right height. The turnbuckle modulates this preload according to the vehicle's load.

⚠️ Signs of wear: when to replace the torsion bar tensioner?

A worn, corroded or out-of-round tensioner shows up gradually, but its effects on handling are significant, particularly on 65C and 70C versions subjected to high loads.

• ❌ Vehicle leans to one side - uneven ride height between left and right sides
• ❌ Inadequate ground clearance on left front, particularly when loaded or going downhill
• ❌ Calibration when cornering or on rough roads - a sign of insufficient preload
• ❌ Urregular wear of front tires linked to poor parallelism induced by height imbalance
• ❌ Corroded, cracked or blocked tensioner noted on under-vehicle visual inspection
• ❌ Suspension bruises at left front on speed bumps or roadway irregularities

🚨 A failing turnbuckle compromises the complete geometry of the front axle. Prompt intervention is essential to avoid premature wear of tires, ball joints and silentblocks, and to preserve the safety of the loaded vehicle.

🔩 Installation and adjustment tips

🔹 Replacement of the tensioner must be followed by adjustment of the body height: act on the tensioner adjustment screw in successive notches until symmetrical height is achieved on both sides.
🔹 Each notch of adjustment allows you to gain approximately 2 to 4 cm of ground clearance - adjust gradually without exceeding the manufacturer's range so as not to stiffen the suspension excessively.
🔹 Simultaneously check the condition of the right-side tensioner: wear is often symmetrical on vehicles with high mileage or regular overloading.
🔹 After replacement and adjustment, a complete front axle geometry is mandatory to correct alignment and avoid premature tire wear.
🔹 Use degripper on threads before disassembly, as corrosion often makes the operation tricky on older vehicles.
💡 Take advantage of the operation to check the condition of the torsion bar silentblocks and suspension arm ball joints, parts frequently stressed at the same mileage.
