24/7 Mobile Truck Repairs Across the Illawarra
When a truck stops, so does your run. At BITR Enterprises, our mobile truck repair service brings the workshop to the roadside, the depot or the job site—anywhere in the Illawarra and surrounding regions, at any hour of the day or night. Our service vehicles carry the tools, diagnostic equipment and commonly needed components to get a large share of faults sorted on the spot, without a tow.
We repair and service all makes and models of trucks, so whether you run a single rigid, a prime mover or a mixed fleet, our technicians know what they are looking at. Every job starts with an honest diagnosis and a clear explanation of what needs doing before we pick up a spanner.
Broken down now? Call us on (02) 4231 4143 and we will get a technician moving.

What Our Mobile Technicians Repair On-Site
Our mobile service covers the everyday faults and the unexpected ones. Common on-site work includes:
- Brake & clutch repairs: Brake adjustments, pad, shoe and disc replacement, air system leaks, and clutch diagnosis, adjustment and replacement so your truck pulls up and takes off exactly as it should.
- General & complete repairs: Engine, driveline, suspension, steering, cooling and air system faults—diagnosed and repaired on-site wherever it is safe and practical to do so.
- Breakdown response: 24/7 emergency attendance for roadside and depot breakdowns, with the aim of getting you rolling again rather than waiting on a tow truck.
- Fault diagnostics: Diagnostic scanning and hands-on testing to find the real cause of a warning light, derate or intermittent fault instead of guessing at parts.
- Servicing & inspections: Scheduled servicing and pre-trip or pre-inspection checks carried out at your yard, so trucks stay compliant without losing a day off the road.
If a repair is too large to complete safely at the roadside, we recover the job into our Unanderra workshop and keep you informed the whole way through.

Detroit Dealer & Authorised Engine Rebuild Centre
BITR Enterprises is a Detroit Dealer for parts and warranty repairs, and an Authorised Engine Rebuild Centre. That means Detroit-powered trucks can be diagnosed, repaired under warranty and fitted with genuine Detroit components by technicians trained on those engines.
It also means we handle full engine rebuilds in-house. When an engine has reached the end of its service life, a properly documented rebuild is often the most cost-effective way to keep a proven truck earning—rather than replacing the whole unit. Every rebuild is carried out to specification, measured, assembled and tested before the truck goes back to work.

Backed by Our Fully Equipped Unanderra Workshop
Our mobile technicians are supported by a fully equipped workshop in Unanderra, giving us the hoists, machining capability and bench space that bigger jobs demand. Complete repairs, driveline work, engine rebuilds and anything needing extended time off the road all happen there.
That combination—mobile response plus a real workshop behind it—is what lets us take a job from the first phone call through to a completed, quality-checked repair. We accept phone bookings and walk-ins, and we service the Illawarra, Wollongong, Shellharbour, Nowra and Sydney.
