4WD Service Tullamarine
Hilux, Ranger, BT-50, Patrol, LandCruiser, Prado, Pajero? We service 4WDs the way they need it — including driveline and pre-trip inspections.
4WD Servicing and Pre-Trip Inspections
A 4WD that's only driven on bitumen needs the same care as any car. A 4WD that sees gravel, sand, salt water or river crossings needs more. Diff oil, transfer case oil, wheel bearings, brakes and suspension all wear faster off-road, and a single wading event in deep water can do damage that doesn't show up for months if it isn't checked.
At 6 Garden Dr we service the popular 4WDs we see most often around Tullamarine, Airport West, Greenvale and the wider north-west: Toyota Hilux, Prado, LandCruiser 70/200/300 series, Ford Ranger, Mazda BT-50, Isuzu D-Max and MU-X, Nissan Patrol and Navara, Mitsubishi Triton and Pajero. We're comfortable with lifted suspension, larger tyres, snorkels, bullbars and tray conversions.
Pre-trip inspections are a specialty. Heading bush or up north? Book it in two weeks out — we'll check the diffs, transfer case, hubs, brakes (especially the rears, which often wear unevenly), suspension under load with whatever you're carrying, cooling system capacity under sustained heat, and recovery points. Better to find a leaking pinion seal in Tullamarine than in Birdsville.
What's Included in Every Car Service
Every 4WD service at our Tullamarine workshop covers the standard service items plus the things 4WDs specifically need: diff oils, transfer case, hub seals, suspension under load, brake performance with extra weight.
4WD Work We Handle
Logbook servicing, off-road repairs, and performance upgrades for utes, wagons, and touring rigs — sorted at our Tullamarine workshop.
4WD Logbook Servicing
Servicing to manufacturer intervals so factory warranty stays intact. Heavier loads, harder use, and longer driveline mean diff oil, transfer case, and front hubs all get checked — not just an oil-and-filter.
Suspension & Lift Kits
Tired OEM springs, blown shocks, or a kit going in? We fit and align suspension upgrades, set ride height, and check guard clearance against tyre size. GVM upgrades discussed where you're hauling weight.
ECU & Performance Tuning
ECU and TCU tuning for diesel utes and wagons — power, torque, and throttle response improved without smoking the EGTs. We tune for how you actually drive, towing or touring, not a dyno number.
Driveline & Transfer Case
CV boots, tailshaft uni-joints, front and rear diffs, transfer case selectors — the bits that get hammered off-road. Diagnosed, rebuilt where the housing is good, replaced when the gears are past it.
Diesel & Exhaust Work
DPF regens, EGR cleaning, intercooler upgrades, and exhaust systems — common ground on tired Patrols, Land Cruisers, Hiluxes, and Rangers. We sort blocked DPFs properly, not just delete and forget.
Pre-Trip Inspections
Heading up the Cape, across the Simpson, or out to the High Country? We go over the rig end-to-end — recovery points, wheel bearings, brakes, cooling, fluids. Better to find it here than out of phone range.

What Our Customers Say
“Sai provided excellent service for my Roadworthy Certificate. The inspection was completed quickly and professionally, and everything was explained clearly. The process was smooth, honest, and hassle-free from start to finish. Highly recommend to anyone needing a Roadworthy Certificate done properly and fast.”
“Sai is the best — if you want to know what's really going on with your car, he's your guy. Patient, thorough, and fair prices. He gave me full evidence of parts replaced and a good inspection. Everyone deserves a proper explanation of how their car is doing.”
“Best service I've ever received. As someone who doesn't know much about cars, I was impressed with how clearly the mechanic explained what needed repairing — they even showed me pictures. I truly felt like I could trust them completely. A trustworthy and reliable place.”
