Specialist pre-purchase 4WD inspection in Sydney — transfer cases, differential locks, off-road systems, lift kits, underbody assessment and full mechanical check. Toyota Land Cruiser, HiLux, Prado, Nissan Patrol, Ford Ranger, Triton, D-MAX and all 4WDs. Mobile, from $275.
Transfer case condition, 4H and 4L engagement, oil level and condition, actuator operation and any fault codes indicating wear — one of the most expensive components unique to 4WDs.
Front and rear diff lock operation, electronic locking diff systems, diff oil condition and any leaks. Both factory (e-LOCKER, Terrain Select) and aftermarket (ARB, Lokka) systems assessed.
Full underbody assessment for off-road damage — chassis rails, diff guards, skid plates, underbody impacts, exhaust, fuel and brake lines — critical for any 4WD with known off-road history.
Lift kits, suspension upgrades, snorkels, bull bars, winches and roof racks assessed for quality, fitment and roadworthiness compliance. Modifications that create safety issues are flagged.
Tow bar condition and rating, receiver hitch, wiring harness, trailer plug and any evidence of towing beyond rated capacity — especially important for 4WDs used to tow caravans and boats.
Road test in 2H, 4H and 4L (where safe and accessible), assessing drivetrain engagement, vibration, noise, steering feel and all dynamic characteristics relevant to off-road use.
Mobile — any seller's address, all Sydney suburbs. Transfer case, diff locks, underbody and full 200+ point check. From $275.
