THE HJ60 is a pretty solid old beast. Like all old LandCruisers it suffers from body rust, but mechanically it's a robust model. The engine is bulletproof, the gearbox is troublefree, but the transfer case can leak oil into the gearbox. Toyota fixed the problem by fitting a return line that pumped the oil back into the transfer case. Front swivel hubs can give trouble if they haven't been properly serviced, 8mm rear hub studs can break, but can be updated to 10mm to fix the problem.
