2020 Toyota 4runner Steering Problems

While driving at 60 mph, your electronic power steering stopped working properly, making it much harder to steer. Your mechanic found that the front timing cover was failing and leaking fluid, which affected the steering system. The issue appeared at 88,000 miles with no warning lights. Fixing this will likely involve replacing the front timing cover and refilling or replacing the power steering fluid.

Your 4Runner vibrates noticeably between 48 and 68 mph, with the worst shaking occurring in the 50-60 mph range. You've had the wheels rebalanced three times, alignment checked twice, and tires inspected by the manufacturer and an authorized retailer, including road force balancing, but the shaking persists. A Toyota service advisor indicated this is a known issue that Toyota Corporate has been contacted about. The vibration could cause premature wear on drivetrain, suspension, and steering components, and may affect vehicle control in adverse weather conditions.

Your steering wheel shakes side to side (up to 1.5 inches) when driving on highways between 58-64 mph, causing the entire vehicle to vibrate. The dealer has tried to fix this six times, including balancing and replacing tires, swapping wheels and drive shafts, and adjusting computer settings—but the problem persists and gets progressively worse. Toyota has acknowledged this as a known issue they attribute to vehicle harmonics. A mechanic will need to diagnose the root cause of the vibration, which could involve suspension components, wheel alignment, or drivetrain parts.
