Your 4WD has spent winter parked under a tarp or working as a weekend runabout, and the tracks you planned for spring are only weeks from being dry enough to tackle. The worst possible discovery is making it to the first river crossing and finding the winch that saved you last year now clicks once and dies.
A spring shakedown is the hour you spend at home so you do not lose a weekend on the trail. It is not a full service — it is a focused once-over of the systems that kill trips: battery, fluids, tyres, recovery gear and electricals. Do it once, keep a list, and it takes less time every year.
Quick answer / TL;DR
Give the rig one disciplined hour before the first spring trip: load-test the battery, check every fluid and belt, inspect and re-seat tyre sidewalls, re-pack the recovery kit, and verify the winch, compressor and every 12V outlet actually work. Fix what fails before you leave the driveway — repairs are always cheaper and faster at home than on a remote track.
Why the spring check matters
Winter is brutal on touring gear even when the vehicle barely moves. Batteries self-discharge and sulphate in the cold, rubber belts and hoses dry out and crack, and tyres develop flat spots and micro-cracks that only show once they are loaded and hot. The bits that spent six months in a damp drawer — recovery straps, winch line, air compressor — need a look too, because UV and moisture do their damage quietly.
The goal is not to find problems. The goal is to find them now, while the spare parts shop is an hour away instead of two days.
Battery and charging system
Load-test the battery
A multimeter reading of 12.6 V with the engine off tells you the battery is charged, not that it is healthy. What kills a trip is a battery that holds surface charge but folds under load — exactly what a cranking battery does when it has sulphated over winter. Get a proper load test at any auto electrician or Supercheap Auto counter; it is cheap and takes minutes. If the battery is over four years old and the test is marginal, replace it now.
Check the charging circuit
With the engine running, voltage at the battery should sit around 13.8–14.4 V. Below that and your alternator or belts are suspect. If you run a dual-battery system or DC-DC charger, verify the auxiliary bank charges correctly too — a winter of sitting can leave the house battery half-flat and unaware.
Test every accessory
Work through the fridge, compressor, winch, UHF, lights and every 12V outlet. A winch that only buzzes needs brushes or a solenoid — far better to learn that in the shed. Charge the drill batteries and lithium packs too; they self-discharge faster than people expect.
Fluids, belts and filters
Fluid checks are ten minutes that prevent most roadside failures. Check engine oil on the dipstick (cold, before a start), coolant level and condition in the overflow, brake fluid, clutch fluid if manual, power steering, and diff and transfer case oils if you have the patience for it. Look at the belts for cracking and glazing, squeeze the radiator hoses for soft spots, and run your hand along them for oil seepage. Change the fuel filter if the rig sat with a partially full tank — condensation in a tank through winter is a common source of poor running in spring.
Tyres and wheels
Sidewall and tread inspection
Winter is when sidewalls suffer — UV, cold and flat spots from sitting. Run your hand around every sidewall feeling for cracks and bulges, check the tread for uneven wear and stones wedged in the pattern, and confirm the spare is in the same condition as the other four. A spare that has lived its life bolted under the tray is often the oldest tyre on the vehicle.
Pressure and re-seat
Check all pressures cold, including the spare. If the vehicle sat for months, rotate the tyres to prevent flat spotting and re-seat the beads by driving a few kilometres before the trip. When was the last time the valve caps were replaced? Grab a handful — they cost nothing and prevent slow leaks.
Wheel bearings and brakes
Jack each wheel and check for play at 12 and 6 o'clock — that is wheel bearing wear. Check brake pad thickness through the caliper and listen for grinding on the first drive. On a caravan or trailer, repeat the same checks on both axles.
Recovery gear and safety
The recovery kit that sat in the back all winter needs a full audit. Inspect the snatch strap for cuts, fraying and UV damage — if it is compromised, retire it, because a strap that lets go is a missile. Check the winch line for broken strands (synthetic) or kinks (wire), the damper for wear, and shackles for cracks and rust. Repack everything dry and clean. The air compressor gets a test run with a tyre back up to pressure, and the tyre deflator, gauge and repair kit get a visual once-over. First aid kit expiry dates and the fire extinguisher gauge are the two items everyone forgets until they are needed.
Real-world tips
- Do the shakedown as a list, not a vibe — tick each system and date the list in the glovebox. It doubles as a service record.
- Load-test the battery and test the winch with the engine running; a winch draws hard and will show a tired alternator immediately.
- Pull the spare down and check it the same as the others — it is the one tyre nobody ever looks at.
- Grease the U-joints, nipples and suspension pivots if the rig sat for months; dry joints wear fast once loaded.
- Book any discovered work for a weekday, not Friday arvo before a long weekend — workshops fill up fast in spring.
- If your 12V accessories draw more than the factory socket can feed, sort the wiring now rather than mid-trip — a quality setup protects both the gear and the battery. See the 12V Accessories collection for plugs, chargers and power supplies that handle the load properly.
Close
None of this is hard and none of it takes a full day. An hour with the bonnet up, a torch and a checklist will catch the tired battery, the cracked belt and the soft spare before they become a two-day wait on a remote track. Get it done before the long weekend, and the first trip of spring is the one that runs on memories instead of breakdowns.
