Why Does the Steering Wheel Become Heavy?

[AthenaDella]

Possible reasons for a heavy steering wheel are as follows: Power Steering Fluid Issue: The most likely cause is dirty or deteriorated power steering fluid, which cannot build sufficient pressure, resulting in reduced power assistance and a heavier steering wheel. Replacing the power steering fluid can resolve this issue. Power Steering Pump Issue: Another possibility is that the power steering pump is about to fail, leading to insufficient oil pressure and reduced power assistance, making the steering wheel heavy. Other causes include overly tight bearings in the steering system, poor lubrication, tight steering tie rod ball joints, or lack of lubrication causing stiffness. Tire Issue: Insufficient tire pressure increases the contact area between the tire and the ground, increasing friction when turning the steering wheel, making it feel heavier.
