Mobile Truck Repairs

Our fully equipped service vehicles come to you anywhere in the Illawarra, 24 hours a day, for breakdowns, brake and clutch repairs and general truck repairs. We work on all makes and models, with our Unanderra workshop backing us up for larger jobs and engine rebuilds.

Truck Parts

As a Detroit Dealer for parts and warranty repairs and an Authorised Engine Rebuild Centre, we stock parts for Detroit, Mercedes-Benz and Freightliner trucks. Everything we sell and fit is backed by the manufacturer's warranty, with trained technicians on hand to help you choose the right component.

Truck Electrical & AC Services

Our auto electricians track down wiring, battery, charging, lighting and warning-light faults across all truck makes and models. We also service and repair truck air conditioning, from regassing to compressor and condenser repairs, in our Unanderra workshop or on-site where practical.

Fleet Servicing & Maintenance

We keep fleets on the road with scheduled servicing, logbook servicing and preventative maintenance planned around your run times. Servicing can be completed at our Unanderra workshop or at your depot, with inspection reports so you can plan repairs before they become breakdowns.

Trailer Repairs, Fabrication & Welding

We repair and service trailers of all makes and models so your loads keep moving safely. Our boilermakers (BPM) and auto electricians (BAE) also handle custom fabrication, chassis and structural welding, on-site or in our Unanderra workshop.
