What Are the Reasons for Heavy Steering in Subaru?
2 Answers
Subaru heavy steering reasons are as follows: 1. Power steering pump failure: When the pump pressure of the power steering pump fails to meet the standard value, the steering wheel will feel heavy during use. It is necessary to check the flow control valve. If the flow control valve or safety valve leaks during driving, it can be repaired by grinding. Then, check whether the spring of the safety valve has failed. 2. Steering gear failure: When the hydraulic pressure of the steering gear is low, the steering will feel heavy. If the heavy steering is caused by the hydraulic pressure of the steering gear, it is necessary to go to a professional manufacturer for repair. It is not recommended for the owner to handle it themselves. 3. Lack of oil or air in the power steering system: When there is air in the car's steering system, not only will the steering feel heavy, but there will also be noise during steering. It needs to be dealt with in time to avoid greater losses. 4. Clogged return oil filter in the oil reservoir: If the return oil filter in the oil reservoir is not maintained or replaced for a long time, it is easy to cause clogging, resulting in poor circulation of the power steering oil and heavy steering.
When driving a Subaru, if the steering wheel feels heavy, the most common issue is a problem with the power steering system. If your car has hydraulic power steering, it's likely that the power steering pump is worn or the belt is loose, causing insufficient pressure. If it's electric power steering (EPS), it could be a sensor malfunction or control module failure. Also, don’t forget to check the power steering fluid level—too little fluid or a leak can make steering heavier. I’ve encountered a similar issue while tinkering in my own garage; just take a moment to unscrew the oil cap and check the fluid level. Tires shouldn’t be overlooked either—low pressure or worn treads can increase friction resistance, making steering feel like pulling a rock. Safety first—heavy steering makes lane changes on highways especially strenuous and prone to accidents. It’s advisable to take some time for a comprehensive inspection at a repair shop—don’t let a minor issue turn into a major one.
