How to Solve Heavy Steering in a Prado?

There is a lack of lubricating oil in the screws inside the steering wheel. This requires removing the steering wheel cover and adding lubricating oil inside. The steering gear may also malfunction. Usually, if the steering is turned too fully during turns, it places a greater load on the steering gear.

When driving a Prado on long trips, I dread sudden steering wheel heaviness the most. If this happens, don’t rush to the repair shop. First, check three things: Low tire pressure can make the steering wheel feel welded in place, especially when fully loaded; for older hydraulic power steering models, check if the steering fluid is dark or low—topping up with specialized oil might help; for newer electric power steering models, focus on inspecting the wheel speed sensors, as mud buildup from off-roading can cause the computer to misjudge. Another small detail: prolonged stationary steering can burn out the power steering motor—this habit needs to change. If the steering mechanism makes a clunking sound after rough roads, it’s likely the steering tie rod ball joint is worn out—replacing it with an OEM part will restore smooth steering.
