At Big Truck Repairs, we’re known for tackling the repairs that others can’t. Recently, we completed a challenging DAF truck chassis repair at our Leeds workshop after a motorway collision left the vehicle with extensive structural damage.
The Incident
This DAF tractor unit was struck on the motorway while attached to its trailer. The collision caused catastrophic damage — the trailer was written off at the scene, and the truck itself suffered severe structural distortion.
Upon arrival at our workshop, inspection revealed that the impact had twisted the chassis at the fifth wheel, leaving it completely misaligned. The rear axle was also out of alignment, and there was significant damage to the air tanks, air bags, suspension components, and the fifth wheel assembly.
Why It Came to Us
Before arriving at Big Truck Repairs, the vehicle had been taken to another workshop. However, the repair proved too complex for them to handle — particularly due to the precision chassis alignment and structural work required. That’s when the owner turned to our Leeds-based specialists, who have extensive experience in heavy vehicle chassis repairs and accident recovery.
The Repair Process
Our team began with a full structural assessment using advanced measuring and diagnostic equipment to determine the extent of chassis twist and axle misalignment.
We mounted the DAF onto our specialist chassis alignment jig, allowing us to realign the chassis rails accurately back to manufacturer specifications. The fifth wheel area, which had absorbed most of the impact, was rebuilt and straightened to ensure safe trailer connection and even load distribution.
All damaged air tanks, suspension components, and air bags were replaced, and the rear axle alignment was recalibrated to restore full handling stability and tyre performance.
Throughout the process, our technicians applied manufacturer-approved methods, ensuring the vehicle’s structural integrity was completely restored.
The Result
After rigorous testing and inspection, the DAF truck was returned to service in fully roadworthy condition. The chassis now sits perfectly aligned, suspension systems function as new, and the fifth wheel coupling operates safely and smoothly.
This repair demonstrated not only the complexity of heavy vehicle collision recovery but also the depth of expertise available at Big Truck Repairs — where no job is too big or too technical.
