Repairs & Rebuilds
At D&D Fleet Engineering, we specialise in heavy-duty repairs and full component rebuilds for public service vehicles. Our team has decades of experience dealing with complex mechanical faults and worn components, and we’re trusted by some of the UK’s biggest fleet operators to keep their vehicles in top condition.
Engine Rebuilds
When an engine is showing signs of serious wear or failure, a full rebuild can offer a cost-effective alternative to replacement. At D&D Fleet Engineering, we carry out complete engine rebuilds either in-chassis or with the engine removed, depending on the needs of the vehicle and the operator.
We begin with a detailed inspection and strip-down to assess all components. From there, we replace worn parts, clean and machine internal components where needed, and rebuild the engine to a high standard. All rebuilds are pressure tested, tuned, and commissioned to ensure performance and reliability.
Whether part of scheduled maintenance or the result of a critical breakdown, our rebuilds are designed to maximise engine life and minimise fleet disruption.
Transmission Repairs
A vehicle’s transmission is key to its overall drivability and efficiency and when something goes wrong, it needs expert attention. We diagnose and repair transmission faults across a wide range of vehicle types, including automatic and manual gearboxes. Common issues such as rough shifting, fluid leaks, or total loss of drive are dealt with quickly and thoroughly, using a combination of diagnostic testing and mechanical expertise.
Where repairs aren’t viable, we can carry out full gearbox replacements, including clutches, flywheels, and related drivetrain components.
Once repairs are complete, every vehicle undergoes road testing to confirm smooth performance and reliability before returning to service.
Axle Repairs
Axles take on a huge amount of strain throughout a vehicle’s working life and even minor issues can cause major knock-on effects. Our axle repair service covers everything from noise and vibration issues to worn bearings, damaged hubs, or full axle failure.
We carry out in-depth inspections to identify the root cause of the issue and carry out repairs or replacements using high-quality parts and approved methods. Whether it’s a minor hub service or a full axle rebuild, we restore the safe handling, stability, and load-bearing performance your vehicle needs to stay roadworthy.
Kingpin Replacement
Kingpins are a small but critical part of the steering and suspension system and when they wear out, they can compromise both vehicle safety and compliance. At D&D Fleet Engineering, we offer professional kingpin replacement services that include accurate removal, reaming, and fitting using specialist tools and techniques.
Our experienced engineers ensure proper alignment and secure installation, restoring steering responsiveness and eliminating excessive play. Every job is completed to DVSA standards, with follow-up checks to ensure continued safety and performance. Whether part of an inspection or reported as a defect, we handle kingpin replacements efficiently and professionally.
