Our Unanderra Workshop
Our fully equipped Unanderra workshop is set up for larger repairs, inspections and scheduled maintenance, and as an authorised Detroit Diesel dealership for parts, warranty repairs and engine rebuilds, we bring dealership-level expertise to every job that comes through the bay. Our licensed technicians (Licence MVRL53638) apply the same standard whether the job's in the workshop or on-site.
While we specialise in trucks and heavy vehicles, our truck mechanic Illawarra team also runs a dedicated mobile mechanic service for on-site diagnostics and repairs, applying advanced diagnostic and repair skills from truck repairs to breakdowns at your depot or roadside where practical. Trailer repairs, fabrication and welding are handled in the same workshop.
Truck Parts And Warranty Repairs
We also stock a wide range of truck spare parts from trusted brands, with manufacturer warranty coverage available on selected products. Our team also provides warranty repairs, helping resolve eligible faults correctly and get your truck back on the road sooner.
