Expert tips to keep your suspension and drivetrain trail-ready across Australia’s diverse climates.
Australia’s rugged landscape demands more from your 4WD than anywhere else on earth. From the heat of the Simpson Desert to the damp, salty environments of the coast, seasonal maintenance is the difference between a successful trip and being stranded. At Tough Dog, we’ve been engineering suspension for Australian conditions since 1985; here is how you should look after your rig year-round.
Our environment is extreme. High heat cycles, deep water crossings in the tropics, and salt spray in coastal areas can accelerate the degradation of rubber bushes, shock absorber seals, and chassis components. Regular maintenance ensures your Tough Dog suspension components continue to provide the handling and control needed for tracks like the Gibb River Road.
Summer heat can affect oil viscosity in your shock absorbers. Before hitting the tracks in your LandCruiser or HiLux, check your shocks for any signs of 'weeping' or oil leaks. Ensure your bushings are not cracked or perished from UV exposure and high road temperatures. Checking your tyre pressures is also critical to ensure the suspension isn't taking unnecessary impact from over-inflated tyres on corrugations.
Mud and salt are the enemies of your chassis and suspension. After tackling a Cape York adventure or beach run, flush your undercarriage thoroughly with fresh water. Inspect your sway bar links, shock shafts, and coil springs for grit buildup. Grit acts like sandpaper on seals; keeping these components clean is a simple step that significantly extends the lifespan of your suspension kit.
While daily checks are good, a deep inspection should occur every 10,000km or before every major trip. Focus on checking for loose bolts, ensuring coil seats are clear of debris, and verifying that the shock absorber mounting points are secure. If you drive a heavily loaded work truck or a tourer like a Patrol or Ranger, ensure your greasable shackles are lubricated regularly to maintain ride comfort.
