Finke Is Coming. Is Your 4WD Ready for the Corrugations?

Finke weekend. Alice Springs turns into a dust bowl, the highway fills with trailers and race trucks, and every 4WD between here and the track gets flogged harder in three days than it does in six months of normal driving.

Whether you're racing, crewing, or just heading out to watch — the corrugations don't care who you are. They'll find the weak points in your vehicle and punish them until something gives.

Corrugations are the real test

Most people worry about the sand and the whoops. But the corrugated sections on the way to the track do more damage than anything else. Thousands of vehicles hitting the same stretch of road at speed creates a washboard effect that shakes every fastener, bush, and mount on your vehicle.

Things we see every Finke week: loose shock bolts, cracked spring mounts, blown bushes, exhaust hangers sheared clean off, battery terminals worked loose, and wiring harnesses rubbing through on chassis rails.

None of these are hard to fix before they fail. Every one of them will ruin your weekend once you're out there.

Suspension takes the beating

Your shocks and springs are doing overtime on corrugations. If your bushes are already worn — and they probably are if you haven't looked at them — you're asking metal to hit metal at 80 km/h on a road that's basically a cheese grater.

Bring it in. We'll torque-check the suspension bolts, inspect every bush, and make sure nothing's about to walk off the car.

Engine bay check — five minutes, not optional

Dust gets into everything. Air filters, electrical connectors, belt pulleys. If your air filter is already half-clogged from daily Alice driving, Finke weekend will finish it off. A restricted air filter on a diesel means higher EGTs, less power, and more fuel going through an already-stressed engine.

Check your air filter. Check your coolant level. Check your fan belt for cracks. Five minutes in the driveway saves you from being the bloke with the bonnet up while everyone else drives past.

Tyres — pressure down, eyes open

Lower your tyre pressures before you hit the dirt. Not just for traction — dropping pressure reduces the shock load on your suspension and chassis. It also reduces your chance of a staked sidewall on a sharp rock.

Carry a spare. Check it before you leave. A flat spare is not a spare.

The Finke pre-check list

• Suspension bolts torque-checked

• Bushes inspected — replace if cracked or perished

• Air filter clean and clear

• Coolant level correct

• Battery terminals tight

• Spare tyre checked and pumped

• Recovery gear on board

Finke is the best weekend on the Central Australian calendar. Don't let a preventable mechanical failure be the reason you miss it.

We don't guess. We test.
