Drivetrain
Drivetrain, Axle & Transmission Service
Wheel-end and axle work is the job most people assume has to go into a shop. With the heavy jacks and tooling on board, most of it does not.
The work
Drivetrain work on site
Drivetrain work is where mobile service either proves itself or falls apart, because it is genuinely heavy. Lifting a loaded Class 8 tractor safely, pulling a hub, setting bearing preload correctly — none of that happens with light equipment. Our units carry the jacks, stands and tooling the work actually requires, which is why axle and wheel-end jobs happen at the yard rather than on a tow bill.
The other half is knowing when not to. A transmission that needs to come out is a shop job, and we will say so.
- Wheel-end, hub and bearing service
- Seal replacement and lubricant service
- Axle and differential diagnosis
- Driveshaft, u-joint and centre bearing work
- Clutch diagnosis and adjustment
- Transmission fault diagnosis, manual and automated
- Suspension-related drivetrain vibration diagnosis
When to call
Symptoms worth a look
- Wheel-end running hot or a seal weeping
- Vibration that changes with road speed rather than engine speed
- Growling or whine that follows load rather than gear
- Shifting complaints on an automated transmission
- Play at the driveshaft or u-joints on a walkaround
Coverage
Engines and makes
Cummins and Detroit Diesel, including Cummins LNG and CNG alternative-fuel systems, across Freightliner, International, Isuzu, Hino, Autocar.
Wheel-end failures are among the most consequential things that can go wrong on a heavy vehicle, and among the most predictable on inspection. Catching them on a PM visit is considerably cheaper than catching them any other way.

Cummins and Detroit Diesel engine work carried out at your yard — diagnosed with OEM software before a single part comes off, by technicians who spent seventeen years doing it inside Freightliner and International dealerships.

Reading a code off a generic scanner tells you a circuit is unhappy. OEM-level diagnostics tell you which part is failing and why — and that difference is usually the whole repair bill.
Read moreDPF & Aftertreatment
A truck that regens constantly is not telling you the filter is full. It is telling you something upstream is putting soot into it faster than it should.
Read moreCNG & LNG Service
Very few shops in Los Angeles will touch a natural-gas heavy-duty engine. If you run CNG or LNG and have been told to take it to a dealer, talk to us first.
Read moreClean Truck Check
A Clean Truck Check failure does not just cost a retest. Compliance is tied to DMV registration — an unresolved failure can stop you registering the unit at all.
Read moreBrake, Air & Suspension
An out-of-service brake defect takes a unit off the board until it is corrected. We carry the components and the tooling to correct it in your yard rather than in a shop queue.
